Diseases And Disorders of The Tongue.

Overview: The tongue is a powerful muscle involved in the critical functions of speaking, chewing and swallowing. Taste buds cover the upper surface of the tongue. A variety of diseases and disorders can affect the tongue including infections, injuries, chronic irritation, abnormal tissue growth and congenital conditions. Many tongue disorders are short-lived; others may cause long-term difficulties, requiring ongoing medical management. Leukoplakia Leukoplakia is a painless grey or white patch on the tongue that develops in response to chronic irritation. These patches can also develop on the inner cheek regions of the mouth. Cigarette or pipe smoking and use of chewing tobacco increase the risk for development of leukoplakia. Irritation caused by poorly fitting dentures or rough spots on the teeth can also lead to leukoplakia. The University of Texas M.D. Anderson Cancer Center reports that approximately one-quarter of leukoplakia patches are cancerous or precancerous. A variant of this disorder known as hairy leukoplakia is caused by the Epstein-Barr virus, and mostly commonly occurs in people with a weakened immune system.

Macroglossia often occurs with certain congenital or inherited conditions, including Down syndrome, Beckwith-Wiedemann syndrome, acromegaly, congenital hypothyroidism and primary amyloidosis. Macroglossia can also occur due to tongue swelling or abnormal tissue growth caused by a variety of disorders including multiple myeloma, sarcoidosis, tongue tumors and certain infections.

What Happens To The Female Brain During Sex?

By: ConsciousnessHealthScience & Tech. When referring to sexual attraction, everything starts from the mind! As new research confirms, everything ends there! U.S. researchers announced that they had solved one piece of the mystery of what happens in the brain during sex by monitoring the activity of the female brain during an orgasm. The research group from Rutgers University in New Jersey, using imaging machines, studied the brains of women during orgasm and found that different brain regions were activated depending on which body part was the source of sexual excitement. Specifically, the scientists identified thirty different parts of the brain that were activated, including the centers responsible for emotion, touch, joy, satisfaction and memory. “Knowing the sequence of events from stimulation to orgasm allows us to see what parts of the brain become activated and in what order. If we can compare this to the brain activity in anorgasmic women, we can see at what point their orgasm gets blocked and work out whether it’s possible to get around that block,” said Barry Komisaruk of the Rutgers University. Two minutes before orgasm the brain centers associated with reward were activated (they also are triggered when we eat and drink). Shortly before orgasm, other brain regions were activated, such as the cortex that receives sensory messages of touch from all over the body. The last brain area to be activated was the hypothalamus, the control center that regulates temperature, hunger, thirst and fatigue.

Why is chewing such an important part of digestion?

By: George Mateljan Foundation.

Chewing is an extremely important, yet oftentimes overlooked, part of healthy digestion. Most people put food in their mouth, chew a few times, and swallow. Yet, in reality it doesn't really take much time and effort to chew your food well. What you get in return is worth the effort in terms of better health and enjoyment of food. How thoroughly to chew While various health professionals advocate distinct numbers of times you should chew food, I recommend more personal guidelines. I feel that this approach will better help you get a sense of your own eating patterns and help you further develop your relationship with your food. My suggestion is that you chew your food completely until it is small enough and dissolved enough to be swallowed with ease. A good rule of thumb is as follows: if you can tell what kind of food you are eating from the texture of the food in your mouth (not the taste), then you haven't chewed it enough. For example, if you are chewing broccoli and you run your tongue over the stalk and can tell that it is still a stalk or over the floret and you can still tell that it is still a floret, don't swallow. You need to keep on chewing until you can't tell the stalk from the floret. The mechanical process of digestion begins with chewing The action of chewing mechanically breaks down very large aggregates of food molecules into smaller particles. This results in the food having increased surface area, an important contributing factor to good digestion. In addition to the obvious benefit of reduced esophageal stress that accompanies swallowing smaller, rather than larger, pieces of food, there is another very important benefit to chewing your food well that comes with its ability to be exposed to saliva for a longer period of time. The chemical process of digestion begins with chewing Food's contact with saliva is important because it helps to lubricate the food, making it easier for foods (notably dry ones) to pass easier through the esophagus. It's also important because saliva contains enzymes that contribute to the chemical process of digestion. Carbohydrate digestion begins with salivary alpha-amylase secreted by glands positioned near the mouth. This alpha-amylase helps break down some of the chemical bonds that connect the simple sugars that comprise starches. Additionally, the first stage of fat digestion also occurs in the mouth with the secretion of the enzyme lingual lipase by glands located at the root of the tongue. Incomplete digestion can lead to bacterial overgrowth When food is not well chewed and the food fragments are too big to be properly broken down, incomplete digestion occurs. Not only do nutrients not get extracted from the food but undigested food also becomes fodder for bacteria in the colon; this can lead to bacterial overgrowth, flatulence, and other symptoms of indigestion. Chewing relaxes the lower stomach muscle Chewing is directly connected with the movement of food through your digestive tract, and, in particular, with the movement of food from your stomach to your small intestine. At the lower end of your stomach, there is a muscle called the pylorus. This muscle must relax in order for food to leave your stomach and pass into your small intestine. Sufficient saliva from optimal chewing helps relax the pylorus, and, in this way, helps your food move through your digestive tract in healthy fashion. Chewing triggers the rest of the digestive process Yet, the contribution of chewing to good digestion does not even stop there. The process of chewing also activates signaling messages to the rest of the gastrointestinal system that trigger it to begin the entire digestive process. This is because when chewing is a well-paced, thorough process, it can actually be said to belong to the "cephalic stage of digestion," the phase in which you first see, smell, and taste your food. The length of time spent chewing the food is related to the length of the cephalic stage of digestion since with more extensive chewing, the longer the food gets to be seen, tasted, and smelled. Cephalic phase responses have been extensively analyzed in the research literature. The release of small messaging molecules that are critical for digestion—such as cholecystokinin, somatostatin, and neurotensin—have been found to increase by over 50% just by the mere sight and smell of food. Additionally, research has shown how chewing, as well as the activation of taste receptors in the mouth, can prompt the nervous system to relay information to the gastrointestinal system to optimize the process of digestion. For example, stimulation of the taste receptors can signal the stomach lining to produce hydrochloric acid that helps in the breakdown of protein. Additionally, chewing signals the pancreas to prepare to secrete enzymes and bicarbonate into the lumen of the small intestines.
