Hypochondrium : ウィキペディア英語版 | Hypochondrium
In anatomy, the division of the abdomen into regions can employ a nine-region scheme, in which the hypochondrium is the upper part of the abdomen on either side, inferior to the thorax, in the area of the lower ribs.〔(thefreedictionary.com )〕 The liver is in the right hypochondrium; the spleen and much of the stomach are in the left hypochondrium. The epigastrium intervenes. ==Definitions, etymology, and modern controversies== The word derives from (ギリシア語:ὑποχονδρος): ''hupochondros'', meaning abdomen, or literally "under cartilage" or "below the cartilage". The word etymologically once referred only to the soft portion of the abdomen between the rib cage and the navel (the region once believed to be the seat of hypochondriasis), but it is not used that way in modern anatomy's schemes for the regions of the abdomen. However, because the hypochondriac areas of the abdominal cavity lie deep to the lower costal cartilages, the etymological notion of "below the cartilage" still works, thanks to the ambiguity of "under/below" (which can be interpreted as either "inferior to" or "deep to"). Some sources have disputed usage of the term for the parts of the anterior abdominal wall below the costal margins. The region named the right hypochondrium exists anatomically, but is almost totally under the chest wall. In clinical situations, the parts of the abdominal wall just below the right and left costal margins are referred to as the right and left hypochondriac regions respectively. Clinically speaking, symptoms and signs arising from this region are of great importance and have a specific list of diseases in their differential diagnoses.〔M. Aroon Kamath, M.D..
