THE ARTERIES. Ill 



Internal Pudic, the smaller of the terminal branches of the anterior trunk, 

 supplies the external generative organs. Its branches in the pelvis are 

 numerous and small, in the perineum they are 

 Inferior Hemorrhoidal. Artery of the Bulb. 



Superficial Perineal. Artery of the Corpus Cavernosum. 



Transverse Perineal. Dorsal Artery of the Penis. 



Sciatic, the other terminal branch, supplies the muscles on the back of the 

 pelvis. Its branches are as follows : 



Muscular Branches. Coccygeal. Muscular, external 



Hemorrhoidal Branches. Inferior Gluteal. to the pelvis. 



Vesical Branches. Comes Nervi Ischiadici. Articular Branches. 



THE POSTERIOR TRUNK gives off the following : 

 Ilio-lumbar, dividing into lumbar and iliac branches. 

 Lateral Sacral, superior and inferior on each side. 



Gluteal, the continuation of the posterior trunk, divides into a superficial and 

 a deep branch, to the glutei muscles, the skin over the sacrum, and the 

 hip-joint. Before dividing it gives a nutrient branch to the ilium, and 

 some muscular branches. 



Describe the External Iliac. It extends to beneath the centre of Poupart's 

 ligament, where it enters the thigh and becomes the Femoral Artery, lying be- 

 tween the femoral vein on the inside and the anterior crural nerve on the out- 

 side V.A.N. Its branches are, small muscular and glandular, and 



Epigastric, which usually arises a few lines above Poupart's ligament, passes 

 between the peritoneum and the transversal is fascia, to the sheath of the 

 rectus which it perforates, and ascends behind that muscle, to anastomose 

 by numerous branches with the terminal branches of the internal mam- 

 mary and inferior intercostal. It gives off 



Cremasteric. Pubic. Muscular Branches. 



Circumflex Iliac, arises opposite to the epigastric, passes along the crest of 

 the ilium to anastomose with the ilio-lumbar, gluteal, lumbar, and epigas- 

 tric arteries. 



Describe the Femoral Artery. It extends from Poupart's ligament to the 

 opening in the adductor magnus, where it becomes the popliteal artery. Its 

 course corresponds to a line drawn from a point midway between the anterior 

 superior spine of the ilium and the symphysis pubis, to the inner side of the 

 inner condyle of the femur. It lies in a strong fibrous sheath with the femoral 

 vein, but divided from the latter by a fibrous partition. It bisects Scarpa's 

 triangle in the upper part of its course, where it is superficial, and rests on the 

 inner margin of the psoas, which separates it from the capsule of the hip-joint 

 Its branches are as follows :
