The porta hepatis or transverse fissure of the liver is a short but deep fissure, about 5 cm long, extending transversely across the under surface of the left portion of the right lobe of the liver, nearer its posterior surface than its anterior border. It joins nearly at right angles with the left sagittal fossa, and separates the quadrate lobe in front from the caudate lobe and process behind. ==Function== It transmits the following:(vein most posterior, duct most anterior)(Anterior to posterior Duct, Artery, Vein respectively) * hepatic portal vein (entering) * hepatic artery proper (entering) * Common hepatic duct (leaving) The hepatic duct lies in front and to the right, the hepatic artery to the left, and the portal vein behind and between the duct and artery. It also transmits nerves and lymphatics. * Sympathetic Nerves - these provide afferent pain impulses from the liver and gall bladder to the brain. Pain may be referred to the lower pole of the right scapula (T7). * Hepatic branch of the Vagus Nerve (CN X). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Porta hepatis」の詳細全文を読む スポンサード リンク
