Anatomy Terminology 1.txt

  1. Abdomen
    The abdomen is the portion of the trunk located between the thorax and pelvis.  It contains the lower part of the esophagus, stomach, small and large intestines, liver, gallbladder, spleen, pancreas, kidneys, and bladder.  A serous membrane called the peritoneum lines this cavity, but not all of the organs in the abdomen are covered by this membrane.
  2. Adhesion
    An adhesion is an abnormal connection formed between two organs or surfaces inside a body cavity.  Adhesions may form following infection, trauma, or surgery.  They may be easily taken down or they may become densely developed causing symptoms and posing significant obstacles during subsequent surgical procedures.

  3. Ancillary
    Ancillary refers to something that assists another action or effect but is not essential to the accomplishment of the action.
  4. Appendix
    The appendix is a worm-shaped process projecting from the blind end of the cecum and is lined with a continuation of the mucous membrane of the cecum.
  5. Bilateral
    Bilateral pertains to, affects, or relates to two sides.
  6. Bile
    Bile is a greenish-yellow or brownish fluid produced and secreted in the liver.  Bile aids in the digestive process by helping to break down fat.
  7. Biliary Tract
    The biliary tract is a system of organs and ducts that participate in the secretion, storage, and delivery of bile into the duodenum (which is the first portion of the small intestine).

    Bladder refers to a membranous sac or receptacle for a secretion, such as the gallbladder or the urinary bladder.
  9. Broad Ligament of the Uterus
    The broad ligament of the uterus contains folds of peritoneum attached to lateral borders of the uterus from insertion of the fallopian tube above the pelvic wall.It consists of two leaves between which are found the remnants of the wolffian ducts, cellular tissues, and the major blood vessels of the pelvis.

    The Common Bile Duct receives bile from the cystic duct of the gallbladder and the hepatic duct from the liver and delivers it to the duodenum.Image Upload 5
  15. Crus
    The Crus is a fibromuscular band rising from the upper three or four lumbar vertebrae and ascending, along with the left crus to insert in the central tendon of the diaphragm (i.e., the right crura is actually divided by the esophagus, causing it to wrap around the esophagus itself).  Therefore, the right crura is actually on the right and left side of the esophagus.  Closing this crura eliminates a potential for herniation into the chest.

  16. Cystic Duct
    The cystic duct is the short duct that leads from the neck of the gallbladder to the common bile duct.  Within the cystic duct is a spiral valve that allows bile to flow in both directions between the gallbladder and the common hepatic duct and the common bile duct.

  30. Gallbladder
    A gallbladder is a hollow muscular, pear-shaped organ that receives bile from the liver and discharges it into the duodenum. While in the gallbladder, the bile is concentrated by removing water.  About 500 to 600ml of bile is secreted each day and it is approximately 82% water.  The bile is then discharged through the cystic duct, which is 3 to 4 inches long.The cystic duct leads to the common bile duct which empties into the small intestine.

    A gallstone is formed in the gallbladder or bile ducts. The most common type is the cholesterol-containing stone.  Gallstones vary in size and chemical structure.  A gallstone may be as tiny as a grain of sand or as large as a golf ball.  Eighty percent of gallstones are composed of cholesterol. They are formed when the liver produces more cholesterol than digestive juices can liquefy.  The remaining 20% of gallstones are composed of calcium and an orange-yellow waste product called bilirubin.
  32. Gastric Ulcer
    A gastric ulcer is an ulcer occurring in the mucous membrane of the stomach.
