tracing the mesal border of the JM. psoas caiidad from this 

 point. 



The nerve lies ectad (ventrad) of the external iliac artery 

 and vein, and entad of the common iliac vein which is ven- 

 trad of and apposed to the artery; it bends around the artery 

 and lies upon its ental surface, ectad (ventrad) of the hypo- 

 gastric artery just cephalad of the ramus pubis. 



It leaves the pelvis through the abdominal ring, 20 mm. 

 peripherad of which it separates into two divisions, one of 

 which (Fig. ce.) is distributed to the integument of the hip 

 (Fig. H.) and the proximal half of the caudal thigh (Fig. 

 Th); the other division (Fig. ca.) is distributed to the in- 

 tegument over the biceps muscle as far as the knee. The 

 nerve was wanting on the sinistral side of one specimen 

 (female). 



N. CRURyEUS ANTERIOR. 



The anterior crural (Ant. Crur.), the seventh lumbar 

 nerve, is the largest of the spinal nerves whose origin is not 

 referable to the union of two or more nerve trunks. It sup- 

 plies 7nusciilar branches to the psoas, the iliacus, the sar- 

 torius, the pectineus muscles and the muscles of the cephalic 

 (inner) thigh except the tensor vaginae femoris, which is 

 innerved by a slender ramus of the superior gluteal nerve 

 (q. v); and cutaneous branches to the integument of the 

 thigh, the leg, the cephalic part of the foot and the plantar 

 surface of the toes. 



The seventh lumbar nerve at the foramen of exit sends 

 anastomotic branches to the adjacent sympathic ganglia; its 

 dorsal division innerves the muscles of the back (Fig. M. 

 dor.) and the adjacent integument (Fig. Int.); the large 

 ventral division (2 mm. in section) lies close to the lateral 

 surface of the centrum and at its ventral border receives the 

 large trunk (Fig. L. S. C.) of the sixth lumbar nerve, and 

 sends an equally large trunk caudad (Fig. L. S. C, lumbo- 

 sacral cord of anthropotomy) to the first sacral nerve.
