Caviar Tongue
Caviar tongue is a condition characterized by the purplish nodular swelling of veins found on the undersurface of the tongue. It is normal for there to be veins visible underneath the tongue, partly because the mucous membrane is so thin and translucent in this region, but where these vessels become dilated and tortuous, they may appear round and black like caviar. However, with caviar tongue, the blood vessels become dilated and tortuous and appear round and black (resembling caviar). Caviar tongue is also referred to as sublingual varices (plural) and varix (singular) and look like varicose veins in the tongue. It is a benign, asymptomatic, venous lesion. History It was first described by William Bennett Bean in 1952, when he thought it looked like caviar. See also * Varicose veins * Varices A varix (pl. varices) is an abnormally dilated vessel with a tortuous course. Varices usually occur in the venous system, but may also occur in arterial or lymphatic vessels. Example ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nodule (medicine)
In medicine, nodules are small firm lumps, usually greater than 1 cm in diameter. If filled with fluid they are referred to as cysts. Smaller (less than 0.5 cm) raised soft tissue bumps may be termed papules. The evaluation of a skin nodule includes a description of its appearance, its location, how it feels to touch and any associated symptoms which may give clues to an underlying medical condition. Nodules in skin include dermatofibroma and pyogenic granuloma. Nodules may form on tendons and muscles in response to injury, and are frequently found on vocal cords. They may occur in organs such as the lung, or thyroid, or be a sign in other medical conditions such as rheumatoid arthritis. Characteristics Nodules are small firm lumps usually greater than 1 cm in diameter, found in skin and other organs. If filled with fluid they are usually softer and referred to as cysts. Smaller (less than 0.5 cm) raised soft tissue bumps may be termed papules. Evaluation The evaluation of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ectasias
Ectasia (), also called ectasis (), is dilation or distention of a tubular structure, either normal or pathophysiologic but usually the latter (except in atelectasis, where absence of ectasis is the problem). Specific conditions * Bronchiectasis, chronic dilatation of the bronchi * Duct ectasia of breast, a dilated milk duct. Duct ectasia syndrome is a synonym for nonpuerperal (unrelated to pregnancy and breastfeeding) mastitis. * Dural ectasia, dilation of the dural sac surrounding the spinal cord, usually in the very low back. * Pyelectasis, dilation of a part of the kidney, most frequently seen in prenatal ultrasounds. It usually resolves on its own. * Rete tubular ectasia, dilation of tubular structures in the testicles. It is usually found in older men. * Acral arteriolar ectasia * Corneal ectasia (secondary keratoconus), a bulging of the cornea. ;Vascular ectasias * Most broadly, any abnormal dilatation of a blood vessel, including aneurysms * Annuloaortic ectasia, ...

Ventral
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek language, Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axis, anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caviar
Caviar (also known as caviare; from fa, خاویار, khâvyâr, egg-bearing) is a food consisting of salt-cured roe of the family Acipenseridae. Caviar is considered a delicacy and is eaten as a garnish or a spread. Traditionally, the term caviar refers only to roe from wild sturgeon in the Caspian Sea and Black Sea (Beluga, Ossetra and Sevruga caviars). The term caviar can also describe the roe of other species of sturgeon or other fish such as paddlefish, salmon, steelhead, trout, lumpfish, whitefish, or carp. The roe can be "fresh" (non-pasteurized) or pasteurized, with pasteurization reducing its culinary and economic value. Terminology According to the United Nations' Food and Agriculture Organization, roe from any fish not belonging to the Acipenseriformes order (including Acipenseridae, or sturgeon ''sensu stricto'', and Polyodontidae or paddlefish) are not caviar, but "substitutes of caviar." This position is also adopted by the Convention on International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Early life and education William Bennett Bean was born in 1909 in the Philippines, to Robert Bennett Bean, a physician who had once been resident under Sir William Osler. He graduated M.D. from the University of Virginia in 1935. The family had previously moved to New Orleans and a few years later to Charlottesville, Virginia, where his father became chairman of the Department of Anatomy at the University of Virginia. He received his B.A. and M.D. from the University of Virginia, in 1932 and 1935, respectively. Following graduation from medical school, with top of the class designation and as president of Alpha Omega Alpha, he interned on the Osler Service at Johns Hopkins University. The following year he moved to Boston and joined the elite group at the Thorndike Laboratory and the Harvard Service at Boston ...

Varicose Veins
Varicose veins, also known as varicoses, are a medical condition in which superficial veins become enlarged and twisted. These veins typically develop in the legs, just under the skin. Varicose veins usually cause few symptoms. However, some individuals may experience fatigue or pain in the area. Complications can include bleeding or superficial thrombophlebitis. Varices in the scrotum are known as a varicocele, while those around the anus are known as hemorrhoids. Due to the various physical, social, and psychological effects of varicose veins, they can negatively affect one's quality of life. Varicose veins have no specific cause. Risk factors include obesity, lack of exercise, leg trauma, and family history of the condition. They also develop more commonly during pregnancy. Occasionally they result from chronic venous insufficiency. Underlying causes include weak or damaged valves in the veins. They are typically diagnosed by examination, including observation by ultrasound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varices
A varix (pl. varices) is an abnormally dilated vessel with a tortuous course. Varices usually occur in the venous system, but may also occur in arterial or lymphatic vessels. Examples of varices include: * Varicose veins, large tortuous veins usually found on legs * Sublingual varices * Esophageal varices, commonly stemming from cirrhosis of the liver, also known as oesophageal varicose * Gastric varices, commonly stemming from cirrhosis of the liver * Intestinal varices * Scrotal varices * Vulvar varices * Pelvic varices * Vesical varices, varicose veins associated with the urinary bladder * Rectal varices, which can be similar to external haemorrhoids See also * Varicose ulcer * Varix (mollusc) A varix () is an anatomical feature of the shell of certain sea snails, marine gastropod molluscs. Gastropods whose shells have varices are primarily families and species within the taxonomic groups Littorinimorpha and Neogastropoda. The va ... References {{Reflist Diseases of ...
