10 Famous Celebrities with OCD

You must have heard of OCD, if not you can find out here What is OCD

Obsessive-compulsive disorder can be an incredible burden to deal with, but it doesn’t mean you can’t succeed. There are a surprising number of famous people with OCD, some of them are listed below.


David Beckham


OCD affects people in the world of sport as well, and one of the most high-profile athletes to suffer from it is soccer star David Beckham. Beckham becomes agitated if objects aren’t arranged precisely, and odd numbers also upset off his obsessive-compulsive mind. He’s even been known to rearrange hotel furniture if it doesn’t line up neatly enough for him. Beckham admits that living with OCD can be quite tiring, but he claims that not giving into his compulsions is even more exhausting because he can’t stop thinking about it.

Megan Fox


One of the most recent celebrities to come out with obsessive-compulsive disorder is the very hot Megan Fox. Fox, who recently announced that she’d reunite with Michael Bay for

"Teenage Mutant Ninja Turtles," has been struggling with the condition for years. Like many OCD people, it manifests as an intense awareness of germs. Fox refuses to use public restrooms or restaurant silverware, and displays some symptoms of agoraphobia. However, after the birth of her son Noah (not really the cleanest of events), she noted that her OCD went heavily into remission.

Marc Summers


It seems impossible that somebody who dealt with cascading green slime and other gak every day on the set of "Double Dare" would have an obsessive fear of germs, but Marc Summers somehow managed to survive it. The Nickelodeon mainstay’s OCD led him to shower immediately after each show, and then again at home the same day. His home was arranged along strict rules and he became upset when anything was out of place. Combinations of behavioral therapy and medication have helped him get it under control.


Cameron Diaz


One of the most public stars in Hollywood when it comes to obsessive-compulsive disorder, Cameron Diaz’s condition manifests itself as an overwhelming fear of germs, especially on doorknobs. In her home, the polish is worn off of every knob because she insists on opening them with her elbows. She also cleans her house daily and washes her hands multiple times every day. Diaz has generally had success controlling her OCD symptoms and it doesn’t affect her work on the set.


Justin Timberlake


It’s interesting that Justin Timberlake and Cameron Diaz dated for so long, considering they both have struggled with obsessive-compulsive disorder. Timberlake is self-diagnosed as having a mixture of OCD and attention-deficit disorder, which seems like a very difficult thing to deal with on a daily basis. Some of the behaviors that he has admitted publicly include making sure things are lined up at perfect right angles and ensuring that certain food items are always present in his fridge.

Leonardo DiCaprio


Actor Leonardo DiCaprio’s obsessive-compulsive tendencies first became apparent when he was a child, as he was constantly forcing himself to step on every gum stain he saw on the sidewalk while avoiding cracks. With time, he managed to overcome that compulsion for the most part, but he admits that it sometimes comes back to plague him. 

Billy Bob Thornton


The iconoclastic actor has dealt with a lot of issues in his life including dyslexia, but obsessive-compulsive disorder is one of his biggest worries. His abusive childhood instilled a number of mental safety valves. Thornton’s OCD manifests itself in repetition – he’s talked about having to take his mail out of his mailbox and put it back in three times, and he also assigns numbers to individual people and mentally refers to them by those numbers. On one of his band’s albums, there’s a song called “Always Countin’” about the condition.

Fiona Apple


It took alternative songstress Fiona Apple seven years to record her latest album, “The Idler Wheel is Wiser Than the Driver of the Screw, and Whipping Cords Will Serve You More Than Ropes Will Ever Do.” The reason? Obsessive-compulsive disorder. Apple’s OCD makes itself known in numerous ways, from straightening out garbage in the trash can to a complete inability to drive. The intensity of her mental condition has essentially made her a hermit, rarely venturing out of her Los Angeles neighborhood except to tour.

Howie Mandel


The host of "Deal or No Deal" is one of the most public OCD sufferers in the entertainment industry. His makeup artists are required to use fresh sponges every day, he never touches handrails, and he won’t put money in his hands until after it’s been washed. Howie’s crippling fear of germs kicks off endless, circular loops of panic around the possibility of getting a disease from any surface. If you meet him, you’ll notice that he refuses to shake hands, preferring a slightly more hygienic fistbump.

Howard Stern


It’s kind of funny that a man who has made a very good living plumbing the depths of human depravity could have OCD, but Howard Stern’s battle with the condition was no laughing matter. When he was first getting his start in broadcasting just out of college, Stern’s anxiety manifested itself as a series of obsessive rituals that he had to perform, including tapping his car radio dial a certain number of times with his right hand before turning it on.

Everything about Root Canal Treatment

A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected.

Root canal procedures are performed when the nerve of the tooth becomes infected or the pulp becomes damaged. During a root canal procedure, the nerve and pulp is removed and the inside of the tooth is cleaned and sealed.

Root canal procedures have the reputation of being painful. Actually, most people report that the procedure itself is no more painful than having a filling placed.

History of Root Canal Treatment 

We can trace the history of root canal surgery (endodontic therapy) back to 1756, when Philip Pfaff published his work on gold as a filler material. A web page at the Oregon State School of Dentistry has a more complete account of the history of root canal surgery.

At the center of every tooth is a hollow area that houses soft tissues, such as the nerve, blood vessels, and connective tissue. This hollow area contains a relatively wide space in the coronal portion of the tooth called the pulp chamber. These canals run through the center of the roots, similar to the way pencil lead runs through a pencil. The pulp receives nutrition through the blood vessels, and sensory nerves carry signals back to the brain. A tooth can be relieved from pain if there is stoppage of root canal when there is pain in the tooth.

Procedures for root canal

The space inside the root canals is filled with a highly vascularized, loose connective tissue, the dental pulp. The dental pulp is the tissue of which the dentin portion of the tooth is composed. The dental pulp helps complete formation of the secondary teeth (adult teeth) one to two years after eruption into the mouth. The dental pulp also nourishes and hydrates the tooth structure, making the tooth more resilient, less brittle and less prone to fracture from chewing hard foods. Additionally, the dental pulp provides a hot and cold sensory function.

Root canal is also a colloquial term for a dental operation, endodontic therapy, wherein the pulp is cleaned out, the space disinfected and then filled

Root canal anatomy consists of the pulp chamber and root canals. Both contain the dental pulp. The smaller branches, referred to as accessory canals, are most frequently found near the root end (apex), but may be encountered anywhere along the root length. The total number of root canals per tooth depends on the number of the tooth roots ranging from one to four, five or more in some cases. Sometimes there are more than one root canal per root. Some teeth have a more variable internal anatomy than others. An unusual root canal shape, complex branching (especially the existence of horizontal branches), and multiple root canals are considered as the main causes of root canal treatment failures. (e.g. If a secondary root canal goes unnoticed by the dentist and is not cleaned and sealed, it will remain infected, causing the root canal therapy to fail).

Root canals presenting an oval cross-section are found in 50%-70% of root canals. In addition, canals with a "tear-shaped" cross section are common whenever a single root contains two canals (e.g., mesial roots of lower molars). Nevertheless, these aspects of root-canal anatomy are not seen or recognized in conventional 2D radiographs, as the long axis of their flat cross section is usually directed in parallel to the direction of the x-ray beam. With the increased use of Cone Beam Computerized Tomography (CBCT), these shapes are likely to be increasingly more often seen and recognized not only by endodontists but also in the clinical environment of general practice.

When rotary NiTi files are used in canals with flat-oval or tear-shaped cross sections, a circular bore is created, while the buccal and/or lingual recesses remain un-instrumented. It takes (a) the awareness that a given canal is flat and (b) expertise in creative use of hand instruments to try to overcome this problem.
Tissue or biofilm remnants along such un-instrumented recesses may lead to failure due to both inadequate disinfection and the inability to properly obturate the root-canal space.

Why Does the Pulp Need to Be Removed?

When nerve tissue or pulp is damaged, it breaks down and bacteria begin to multiply within the pulp chamber. The bacteria and other decayed debris can cause an infection or abscessed tooth. An abscess is a pus-filled pocket that forms at the end of the roots of the tooth. An abscess occurs when the infection spreads all the way past the ends of the roots of the tooth. In addition to an abscess, an infection in the root canal of a tooth can cause:

Swelling that may spread to other areas of the face, neck, or head
Bone loss around the tip of the root
Drainage problems extending outward from the root. A hole can occur through the side of the tooth with drainage into the gums or through the cheek with drainage into the skin.

What Are the Signs When Root Canal Treatment is needed?

Severe toothache pain upon chewing or application of pressure.
Prolonged sensitivity/pain to heat or cold temperatures (after the hot or cold has been removed).
Discoloration (a darkening) of the tooth.
Swelling and tenderness in the nearby gums.
A persistent or recurring pimple on the gums.

Over-the-counter laxatives for constipation

Laxatives can help relieve and prevent constipation. But not all laxatives are safe for long-term use. Overuse of certain laxatives can lead to dependency and decreased bowel function.

If you've ever experienced the discomfort of constipation, perhaps while traveling or after a change in your diet you may have considered over-the-counter laxatives. Over-the-counter laxatives come in many different forms viz liquids, tablets, wafers, gums, or powders that you dissolve in water. You take rectal laxatives in the form of suppositories or enemas.

How often you have a bowel movement varies, but a "normal" frequency ranges from as many as three bowel movements a day to about three a week. Your body ordinarily needs no help to have bowel movements. But a poor diet, physical inactivity, pregnancy, illness or some medications can disrupt normal bowel function and cause constipation.

Before trying laxatives

Before turning to laxatives for relief, try these lifestyle changes to help manage occasional irregularity:

Eat fiber-rich foods, such as wheat bran, fresh fruits and vegetables, and oats.
Drink plenty of fluids daily.
Exercise regularly.
Lifestyle and dietary improvements relieve constipation for many people, but if problems continue despite these changes, your next choice may be a mild laxative.

How laxatives relieve constipation

Laxatives work in different ways, and the effectiveness of each laxative type varies from person to person. In general, bulk-forming laxatives, which are also referred to as fiber supplements, are the gentlest on your body and safe to use long term. Metamucil and Citrucel fall into this category. Stimulant laxatives, such as Ex-Lax and Senokot, are the harshest and shouldn't be used long term.

Following are some examples of common types of laxatives. Other types also exist. Even though many laxatives are available over-the-counter, it's best to talk to your doctor about laxative use and which kind may be best for you.

Type of laxative, How they work & their Side effects

Oral osmotics (Phillips' Milk of Magnesia, Miralax): Draw water into colon from surrounding body tissues to allow easier passage of stool.

Side Effect: Bloating, cramping, diarrhea, nausea, gas, increased thirst

Oral bulk formers (Benefiber, Citrucel, Fiber Choice, Metamucil): Absorb water to form soft, bulky stool, prompting normal contraction of intestinal muscles.

Side Effect: Bloating, gas, cramping, choking or increased constipation if not taken with enough water

Oral stool softeners (Colace, Kaopectate): Add moisture to stool to allow strain-free bowel movements.

Side Effect: Throat irritation, cramping

Oral stimulants (Ex-lax, Senokot): Trigger rhythmic contractions of intestinal muscles to eliminate stool.

Side Effect: Belching, cramping, diarrhea, nausea, urine discoloration

Rectal stimulants (Bisacodyl, Pedia-Lax, Dulcolax): Trigger rhythmic contractions of intestinal muscles to eliminate stool.

Side effect: Rectal irritation, stomach discomfort, cramping

Oral laxatives may interfere with your body's absorption of some medications and food nutrients. Rectal laxatives do not have this effect. Also, some oral and rectal laxatives can lead to an electrolyte imbalance, especially after prolonged use. Electrolytes, which include calcium, chloride, potassium, magnesium and sodium, regulate muscle contraction, heart rhythm, nerve function, fluid balance and other body functions. An electrolyte imbalance can cause abnormal heart rhythms, weakness, confusion and seizures.

Combination laxatives: Check labels carefully

Some products combine different types of laxatives, such as a stimulant and a stool softener. Combination products may not be any more effective than are single-ingredient products. But they may be more likely to cause side effects because of their multiple ingredients. Read labels carefully to see how many types of laxatives a product contains.

Risks of laxative use

Interaction with medications
Your medical history and other medications you're taking may limit your laxative options. Laxatives can interact with blood thinners such as warfarin (Coumadin), antibiotics such as tetracycline, and certain heart and bone medications. Before using any laxative, read the label carefully. If you're not sure whether a particular laxative is right for you, ask your pharmacist or doctor. Don't exceed recommended dosages unless your doctor tells you otherwise.

Complicating conditions 

Just because laxatives are available without a prescription doesn't mean that they're without risk. Laxative use can be dangerous if constipation is caused by a serious condition, such as appendicitis or a bowel obstruction. If you frequently use certain laxatives over a period of weeks or months, they can decrease your colon's natural ability to contract and actually worsen constipation.

Precautions for pregnant women and children 

Don't give children under age 6 laxatives without a doctor's recommendation. If you're pregnant, get your doctor's advice before using laxatives. Bulk-forming laxatives and stool softeners are generally safe to use during pregnancy, but stronger laxatives can harm you or your baby. The stimulant laxative castor oil, for example, can cause uterine contractions. If you've recently given birth, consult your doctor before using laxatives. Although they're usually safe to use during breast-feeding, some ingredients may pass into breast milk and cause diarrhea in nursing infants.

Don't be lax about laxatives

Call your doctor immediately if you have bloody stools, severe cramps, pain, weakness, dizziness, unusual tiredness or rectal bleeding. You should also see a doctor if you have unexplained changes in bowel patterns or habits or if constipation lasts longer than seven days despite laxative use. If you're dependent on laxatives to have a bowel movement, ask your doctor for suggestions on how to gradually withdraw from them and restore your colon's natural ability to contract.

10 Tips To Relieve Constipation

Drink Plenty of Fluids

Drinking extra fluids may not relieve your constipation, but it can make stools softer and easier to pass. Getting enough fluids can also help prevent dehydration, which can cause constipation. Carry a water bottle with you and keep it filled. If you can’t get clean tap water, drink plenty of bottled spring water, fruit juice, or other non-caffeinated drinks.

Limit Low-Fiber Foods

Many of the foods you might love on vacation -- like snack foods and dessert -- can actually make constipation worse. Common culprits include cheese, sweets, meats, pizza, processed foods, chips, and ice cream. If constipation becomes a problem, limit these foods to occasional treats.

Don't Forget Fiber

Trading in your whole grain cereal for chocolate croissants while on vacation? Then make sure to get fiber somewhere else in your diet. Not eating enough fiber is a common cause of constipation, whether you’re on vacation or not. Try eating 2 1/2 cups of vegetables and 2 cups of fruit every day. Beans and whole grain breads also help add bulk.

Limit Caffeine and Alcohol

Drinking a margarita by the poolside may sound heavenly, but it could add to your constipation problems. Alcohol and caffeine can cause dehydration. If you’re prone to constipation while traveling, try to limit alcohol and drinks with caffeine. Or, drink plenty of water when you enjoy these beverages to make sure you stay hydrated.

Stay Active

Traveling often means sitting -- in a car, train, boat, or plane. Unfortunately, when you stop moving, so may your bowels. If you’re sitting for long periods of time, take frequent breaks to move around. And once you reach your destination, schedule physical activities -- like long walks or bike rides -- to get your body moving.

Don't Ignore Your Body

There are many reasons why you might ignore the urge to have a bowel movement while on vacation. You might feel uncomfortable using a public restroom or be too busy sightseeing to find a place to go. But ignoring the urge can sometimes lead to constipation. Instead of putting it off, use the restroom when you feel the need to.

Plan for Bathroom Breaks

If you usually use the restroom at a certain time of day, try to plan for this during your vacation. Give yourself time to relax. You may find reading a magazine or newspaper helps. If you don’t have a bowel movement in 10 minutes, try again later when you have the urge.

Prepare for Travel

If you often have constipation when you travel, prepare ahead of time. One way is to start taking a stool softener or a bulk-forming laxative a few days to a week before you leave. Then continue taking it while you’re on vacation. This will help soften your stool and make it easier to pass.

Use Laxatives Wisely

If diet and exercise don't help, you may want to try a laxative. Using laxatives too often can make your body dependent on them. So you should only use them for a short time. Many types of laxatives are available over the counter. In some cases, you may need a prescription laxative. Ask your doctor what's best for you.

When to Get Help

In some cases, constipation can cause hemorrhoids or tears in the skin around the anus. This can lead to bleeding from the rectum or blood in your stool. In more severe cases, constipation can lead to impaction, where stool becomes stuck in the rectum. If you have blood in your stool, or if your constipation is so severe that you cannot pass any stool, call your doctor.

What Is Galvanic Shock?

Galvanic shock is a type of dental pain experienced as a sharp, jolting sensation in one or more teeth. As the name suggest, the pain associated with galvanic shock is caused by an actual electric shock. This shock is caused when the filling of one tooth, containing gold, touches the filling of another tooth, containing amalgam. Galvanic shock is also commonly experienced when the metal in a tooth comes into contact with aluminum foil.

 Galvanic shock gets its name from the current that causes it. Today known as a "direct current," galvanic current is electricity flowing in one constant direction. Saliva facilitates the shock by functioning as an electrolyte. It contains free ions which create an electrically conductive environment.

Treatment: If the galvanic shock stems from two unlike metals placed next to each other, such as in fillings, one of the fillings may need to be replaced with a non-metallic substance, such as porcelain.

Do Airport X-Ray Scanners Cause Cancer?

According to one report from PBS/ ProPublica, anywhere from six to 100 passengers each year could get cancer from these machines.  The study said that any exposure to ionizing radiation – the kind emitted by the x-ray scanners – increases risk of cancer. Though the machines emit fewer than 10 micro-rems of radiation - which is roughly one-thousandth of the exposure of a chest x-ray-- the National Academy of Sciences has found no evidence that exposure to radiation – even in the smallest amounts – has a zero risk of cancer. In other words: it's possible that these machines cause cancer. A 2011 report from the University of Columbia Center for Radiological Research said that one billion x-ray scans per year could lead to 100 radiation-induced cancers. These one billion scans would be accumulated by a pool of 100 million frequent flyers.

In 1999, the Conference of Radiation Control Program Directors, a nongovernmental organization, passed a resolution recommending that the full-body scanners now used in airports be stopped immediately.

In November 2011, the European Union banned use of the body scanners in its airports due to safety concerns.  Only England's Manchester Airport continues to use the machinery.

In a 2011 study from the University of California, San Francisco, airport scanners were found to potentially cause up to six cases of cancer over the course of a lifetime in those people exposed to the scanners – which totals over 100 million people.  So the risk is tiny, according to this study.

The Transportation Safety Administration swears that the machines are safe, stating that the amount of radiation to which people are exposed is minute and worth the risk – as small as it may be – for the increase in security.  The Food and Drug Administration says that the risk of cancer is one in 400 million, citing the National Council on Radiation Protection and Measurements.

Europe has banned airport scanners over cancer fears. England's Manchester Airport is the only airport in Europe that still uses the back-scatter scanners.

Do you think these machines are safe?

10 Most Common Symptoms of Low Blood Pressure

Low blood pressure occurs when the pressure of the blood that is exerted against the walls of the blood vessels after and during every heart beat is lower than normal. This can result in insufficient supply of blood to the important organs of the body like the heart and the brain and can also lead to various low blood pressure symptoms.

Following are the most common symptoms of low blood pressure:

1. Dizziness and lightheartedness
2. A tendency to faint
3. Pain in the chest
4. Black or maroon colored stools
5. Irregular heart beat
6. Head ache
7. Back pain or Stiff neck
8. Consistent high fever
9. Wheezing and
10. Burning sensation in the urine

If you happen to spot any of the above symptoms of low blood pressure, it is recommended to seek doctor's advice as soon as possible.

Because of low blood pressure, proper amount of blood is not able to reach to all the parts of the body and thus the cells do not receive the correct amount of oxygen and nutrients. Therefore, the waste products in the blood are not removed.

Don't overlook the risk of low blood pressure if you cough with phlegm or if you are suffering from prolonged diarrhea, or if you are unable to eat or drink, or if you experience burning urinary symptoms or even if you are taking new medicines, because all these are low blood pressure symptoms.

When you start experiencing low blood pressure symptoms, remember that the brain is the first organ to malfunction in such situations because it's located at the top of the body and as a result you will experience dizziness or even fainting. You should remember that if you don't treat low blood pressure seriously it might lead to brain damage.

Due to low blood pressure, blood is not adequately supplied to the heart muscles and therefore breathlessness and chest tightness forms one of the common low blood pressure symptoms. When you have prolonged low blood pressure all organs start malfunctioning and this leads to shock.

In order to prevent the situation from getting worse, you should take certain precautionary measures when you have low blood pressure and you must take your doctor's advice. You should try to be more physically active and must also try to lose weight. You should also maintain a healthy diet and limit the consumption of alcohol. All these measures will help you to keep your low blood pressure symptoms under control.

In spite of all the harmful aspects of low blood pressure, researchers say that it is better than high blood pressure because people experiencing low blood pressure symptoms tend to live longer than people suffering from high blood pressure symptoms do.

If you suspect yourself to be suffering from low blood pressure you should consult your medical health practitioner.

How you can reduce mobile radiation exposure

A World Health Organization panel has concluded that cell phones are "possibly carcinogenic,'' putting the popular devices in the same category as certain dry cleaning chemicals and pesticides, as a potential threat to human health. There is sufficient data to show that cell phone use affects brain activity and brain glucose levels after use and the World Health Organization declared cell phone radiation to be a potential carcinogen. So there is definitely enough cause for concern.
Here are some tips to reduce exposure to mobile radiations:

  1. Use a wired headset to minimize the waves hitting you.
  2. Talk on a speakerphone whenever possible
  3. Don't wear Bluetooth continuously
  4. Avoid using phone in enclosed areas
  5. Hold phone little away while talking.
  6. Send text messages
  7. Choose a phone that emits less radiation. More manufacturers are becoming conscious of the health risks and attempting to manufacture lower radiation models. A Google search can help you identify one the next time you are in the market for a cell phone.
  8. Choose natural supplements known to reduce cell damage from radiation like alpha lipoic acid and vitamins C and E.
  9. Eat more seaweed. Seaweed is nature’s anti-radiation remedy. 
  10. Keep the phone away from your bed. Sleeping with the phone near your head, such as on your night stand, can expose you to radiation for long periods of time.
  11. Don’t put it in your pocket. If you must, keep the phone’s antenna (usually on the back of the phone) facing away from your body.
  12. Watch the signal strength. When the signal strength is weak the phone will emit MORE radiation in an attempt to communicate with the cell tower.

6 ways to Boost Low Testosterone Level Naturally

Testosterone is a male steroid hormone, it is necessary for development and maintenance of various masculine characters. In addition Testosterone is essential for health and well being as well as prevention of osteoporosis. Testosterone level starts declining after 30 years of age, which results in symptoms such as decreased sex drive, erectile dysfunction, depressed mood, and difficulties with concentration and memory. So you must know how to maintain adequate level of this crucial hormone.

To maintain a healthy level of Testosterone you should :-

Get Enough Sleep.

Poor sleep is the most important factor. A lack of sleep affects a variety of hormones and chemicals in your body. This can have a harmful impact on your testosterone. Sleep for seven to eight hours per night, avoid late-night TV and other harmful habits.

Maintain Healthy Weight.

Men who are overweight or obese often have low testosterone levels. Losing the extra weight can help bring testosterone back up. Likewise, for men who are underweight, getting your weight up to a healthy level can also have a positive effect on the hormone levels.

Exercise is must.

Testosterone adapts to your body's needs. If you spend most of your time lying on the couch, your brain gets the message that you don't need as much to bolster your muscles and bones, but when you are physically active, your brain sends out the signal for more production of the hormone. But remember too much endurance can actually lower your testosterone levels.

Take Control of Your Stress.

If you're under constant stress, your body will release out the stress hormone cortisol. Cortisol is antagonist of testosterone, so the testosterone level will drop. So, controlling your stress is important for keeping up your testosterone. Yoga, Music and Meditation are pretty helpful in relieving stress. Try out any of these.

Review Your Medications.

Some medicines can cause a drop in your testosterone level. These drugs include-

Opioid drugs such as fentanyl, MS Contin, and OxyContin.
Glucocorticoid drugs such as prednisons.
Anabolic steroids used for building muscles and improving athletic performance.

You shouldn’t stop taking any of your medications. If you're concerned about your testosterone level, discuss your medications with your doctor to make sure they're not the problem and to make adjustments to your treatment if needed.

No need of Testosterone Supplements.

Finally, although you're likely to encounter online ads for testosterone-boosting supplements, you aren't likely to find any that will do much good. Your body naturally makes a hormone called DHEA that it can convert to testosterone. DHEA is also available in supplement form. But they will do little to actually raise your testosterone.

Everything you should know about Beta Blocker

Beta blockers (β-blockers) are a class of drug which target the beta receptor present on the cells of the heart muscles, smooth muscles, airways, arteries, kidneys, and other tissues that are part of the sympathetic nervous system and lead to stress responses, especially when they are stimulated by epinephrine (adrenaline). Beta blockers interfere with the binding to the receptor of epinephrine and other stress hormones, and weaken the effects of stress hormones.
They are particularly used for the management of cardiac arrhythmias, protecting the heart from a second heart attack (myocardial infarction) after a first heart attack (secondary prevention), and hypertension.
In 1962, Sir James W. Black found the first clinically significant beta blockers—propranolol and pronethalol; it revolutionized the medical management of angina pectoris and is considered by many to be one of the most important contributions to clinical medicine and pharmacology of the 20th century.
Beta blockers block the action of endogenous catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline) in particular, on β-adrenergic receptors, part of the sympathetic nervous system which mediates the fight-or-flight response. Three types of beta receptors are known, designated β1, β2 and β3 receptors.
β1-adrenergic receptors are located mainly in the heart and in the kidneys. β2-adrenergic receptors are located mainly in the lungs, gastrointestinal tract, liver, uterus, vascular smooth muscle, and skeletal muscle. β3-adrenergic receptors are located in fat cells.


Canine Catching Disorder

Like Human Beings Dogs also have something like OCD, which is known as ‘Canine Catching Disorder’.
Do you have a Dog?
Does he tries to catch or bite his tail?
If yes, how frequently?
May be your Dog is suffering from this disorder. Other symptoms of this disorder include recurrently chasing light or shadow.
Interestingly, like in Human OCD vitamin and mineral supplements are also beneficial for Canine Catching Disorder. Dogs feeded with these supplement chased their tail less frequently.
About 2% Dogs have this disorder. Most of them develop it before reaching sexual maturity.
If your Puppy or Dog is also suffering from this disorder then feed him well, provide national supplements if needed and don’t stimulate his obsession like if he is obsessed with some torch light, avoid it.

Anatomy Exceptions


All intrinsic and extrinsic muscles of the tongue are supplied by the hypoglossal nerve (CN XII), except for one of the extrinsic muscles, palatoglossus, which is innervated by CN X (VAGUS).


All the muscles of the soft palate receive their motor supply from the vagus nerve (X), except the tensor veli palatini which is supplied by medial pterygoid nerve (branch of mandibular nerve). 


All the muscles of mastication receive their motor supply from the mandibular nerve (V3), except the Geniohyoid which is supplied by C1 via cranial nerve XII.


All the exocrine glands in the head and neck receive their parasympathetic supply via the facial nerve (VII) via submandibular ganglion, except the Parotid gland.


All intrinsic muscles of larynx, except cricothyroid, are innervated by the recurrent laryngeal nerve with fibres from the accessory nerve (CN XI). The external laryngeal nerve supplies the cricothyroid muscle.


The pharyngeal plexus (with fibers from CN IX, CN X, and cranial part of CN XI) innervates all the muscles of the pharynx (except stylopharyngeus, which is innervated directly by a branch of CN IX (Glossopharyngeal).


Unlike the other exocrine glands in the head and neck, the parotid gland receives its parasympathetic supply from the Glossopharyngeal nerve via the Ottic ganglion


When we grit our teeth, we employ the mandibular nerve. This nerve also supplies Tensor veli palatini & Tensor tympani.


Sensory supply from the external nose and nasal cavity is via CN V1 & V2.

Parasympathetic supply to the nasal cavity and palate is via CN VII via the Pterygopalatine ganglion


Tactile sensory supply from the anterior 2/3 of the tongue is via CN V3 (Mandibular nerve).

Both tactile and taste sensory supply from the posterior 1/3 of the tongue is via CN IX.
Parasympathetic supply to the tongue is via CN VII via the Submandibular ganglion.


Sensory supply from the palate is via CN V2 (Maxillary nerve).

What is Funny Bone?

Actually funny bone isn't a bone its Ulnar Nerve which is present superficial to humerus bone and this nerve is the largest unprotected nerve in the human body so when it gets hit it feels weird.

In human anatomy, the ulnar nerve is a nerve which runs near the ulna bone. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. This nerve is directly connected to the little finger, and the adjacent half of the ring finger, supplying the palmar side of these fingers, including both front and back of the tips, perhaps as far back as the fingernail beds. One method of injuring the nerve is to strike the medial epicondyle of the humerus from posteriorly, or inferiorly with the elbow flexed. The ulnar nerve is trapped between the bone and the overlying skin at this point. This is commonly referred to as bumping one's "funny bone".
