Human anatomy, including structure and development and practical considerations . y certain size orshape. Its diameter from above downward is probably rarely less than 7 cm. andmay be greater. It is separated from the neck by a groove on the front of the gUuulfor the gastro-duodenal branch of the hepatic artery. It rests behind on the inferiorvena cava, sometimes on the right renal vein, and may approach the right suprarenalbody. It is op])i)site the first and second lumbar vertebrae and often a part of thethird lumbar \ ertebra. The body (corpus jiaiicrcatis), including the neck and tail, is prismatic, ha\inga posterior, an antcro-sHpcrior, and a narrow inferior surface. It is so t(jrtuous inits natural position as to seem shorter than it is. Starting on the right of the spineat the level of the first lumbar vertebra, it passes around it to the left and h)ackwardand again forward to the spleen, which it may or may not cross. Towards its endit also turns downward. Portal vein Fig. 1461. Hepatic artery Left suprarenal body Left kidney Ri^ht suprarenal-body Vena cava.

The neck is the part (^2-3 cm. in length) which crosses the portal vein with aforward convexity, being deeply grooved by the vein on its posterior surface. Theleft extremity of the body is the tail (cauda pancreatis), the end of which is veryvariable in form. If it lies in front of the spleen it is more or less pointed, but if itends against the gastric surface of that organ it may have a true terminal concavesurface, fitting it accurately TFig. 1461). The posterior surface has first (from the neck towards the left) the deepgroove for the portal vein, which may be entirely surrounded
