. Anatomy, descriptive and applied. Anatomy. THE LIVER 1323 vein in the fetus, and its remains {ligamentum teres) in the adult; it h'ts between the quadrate lobe and the left lobe of the liver, and is often partially bridged over by a prolongation of the liepatic substance, the pons hepatis. The posterior part or fissure for the ductus venosus {fossa ductus veiiosi.) lies Ijetween the left lobe and the Spigelian lobe; it lodges in the fetus the ductus venosus, and in the adult a slender fibrous cord (lig. venosum) the impervious remains of that vessel. The transverse or portal fissure (porta hepatis) (Fig. 1084) is a short but deep fissure, about two inches (5 cm.) in length, extending transversely across the under surface of the left portion of the right lobe, nearer to its posterior surface than its anterior border. It joins, nearly at right angles, with the longitudinal fissure, and separates the quadrate lol^e in front from the caudate and Spigelian lobes behind. By the older anatomists this fissure was considered the gateway (porta) of the liver; hence the large vein which enters at this fissure was called the portal vein (Fig. 1085). Besides this vein, the fissure transmits the hepatic artery and nerves, and the hepatic duct and lymphatics. At their entrance into the fissure, 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. iV'snn'haqeal qroove.

The fossa or fissure for the gall-bladder (fossa vesicae felleae) is a shallow, oblong fossa, placed on the under surface of the right lobe, parallel with the longitudinal fissure. It extends from the anterior free margin of the liver, which is notched for its reception, to the right extremity of the tra
