| segmenta hepatis | Territories of the liver with independent portobilioarterial distribution or independent venous drainage. The naming of segments in the NA is based upon the portobilioarterial distribution. See: anterior segment, lateral segment, medial segment, posterior segment.

| impressio cardiaca hepatis | A depression on the superior area of the diaphragmatic surface of the liver corresponding to the position of the heart. Synonym: impressio cardiaca hepatis. (05 Mar 2000) |
| incisura ligamenti teretis hepatis | The notch in the inferior border of the liver that accommodates the round ligament. Synonym: incisura ligamenti teretis hepatis, incisura umbilicalis, umbilical notch. (05 Mar 2000) |
| tunica fibrosa hepatis | A layer of connective tissue ensheathing the hepatic artery, portal vein, and bile ducts as these ramify within the liver. Synonym: capsula fibrosa perivascularis, perivascular fibrous capsule. Connective tissue capsule surrounding the outer surface of the liver, but continuous with septae of some animals which divide parenchyme into lobule, and with the perivascular fibrous capsule at the porta hepatis. Synonym: tunica fibrosa hepatis, Glisson's capsule. (05 Mar 2000) |
| tunica serosa hepatis | Serous coat of the liver; peritoneal covering of the liver, enclosing almost all except for a triangular area on its posterior surface, (the "bare area of the liver") and a smaller area where the liver and gallbladder are in direct contact. Synonym: tunica serosa hepatis. (05 Mar 2000) |
| facies visceralis hepatis | The posteroinferior surface of the liver that faces adjacent abdominal organs; the porta hepatis and gallbladder are located on this surface. Synonym: facies visceralis hepatis. (05 Mar 2000) |
| ligamentum coronarium hepatis | Peritoneal reflections from the liver to the diaphragm at the margins of the bare area of the liver. Synonym: ligamentum coronarium hepatis. (05 Mar 2000) |
| ligamentum falciforme hepatis | A crescentic fold of peritoneum extending to the surface of the liver from the diaphragm and anterior abdominal wall; the round ligament lies in its free inferior border, derivative of embryonic ventral mesogastrium. Synonym: ligamentum falciforme hepatis. (05 Mar 2000) |
| ligamentum teres hepatis | The remains of the umbilical vein running within the free edge of the falciform ligament from umbilicus to the liver, where it continues within the fissure for the round ligament to the origin of the left portal vein within the porta hepatis. Synonym: ligamentum teres hepatis. (05 Mar 2000) |
| lobulus hepatis | The conceptual polygonal histologic unit of the liver consisting of masses of liver cells arranged around a central vein, a terminal branch of one of the hepatic veins; at the periphery are located preterminal and terminal branches of the portal vein, hepatic artery, and bile duct, hepatic lobules have anatomical reality in the pig liver or pathologically in humans, when fibrous septa are present. Synonym: lobulus hepatis. (05 Mar 2000) |
| lobus hepatis dexter | The largest lobe of the liver, separated from the left lobe above and in front by the falciform ligament and from the caudate and quadrate lobes by the sulcus for the vena cava and the fossa for the gallbladder; it contains two segments, anterior and posterior. Synonym: lobus hepatis dexter. (05 Mar 2000) |
| lobus hepatis sinister | It is separated from the right lobe above and in front by the falciform ligament, and from the quadrate and caudate lobes by the fissure for the ligamentum teres and the fissure for the ligamentum venosum; the distribution of the portal vein, hepatic artery, and bile ducts does not correspond to the gross lobar divisions of the liver. It contains two segments, superior and inferior. Synonym: lobus hepatis sinister. (05 Mar 2000) |
| agger valvae venae | A slight eminence on the external wall of a vein correlating with the valvular sinus immediately proximal to the leaflets of the venous valve. Synonym: agger valvae venae. (05 Mar 2000) |
| Billroth's venae cavernosae | Small tributaries of the splenic vein in the pulp of the spleen. Synonym: Billroth's venae cavernosae. (05 Mar 2000) |
