ligament, and below by the opening in the great adductor muscle, after passing 

 through which the artery receives the name of popliteal. 



At its commencement the femoral artery is of the same *>ize as the external iliac

a, anterior superior iliac spine ; 6, tensor vagina? 

 feraoris muscle ; c, vastus internus ; d, tendon of 

 adductor magnus ; e, sartorius ; /, rectus ; g, ter- 

 mination of colon, lying upon the left external iliac 

 artery ; h, urinary bladder ; 1, bifurcation of ab- 

 dominal aorta ; 1', middle sacral artery ; 2, left 

 common iliac artery ; 3, external iliac ; 3', deep 

 circumflex iliac ; 3", epigastric, winding to the 

 inner side of the spermatic cord, and giving off 

 3'", its cremasteric branch ; 4, 4, femoral artery, on 

 the right side shown in Scarpa's triangle, on the left 

 exposed in Hunter's canal ; 4', superficial circumflex 

 iliac and epigastric of the right side ; 4", super- 

 ficial pudic branches ; 5, deep femoral artery, 

 descending on the left side behind the adductor 

 longus ; 6, external circumflex ; 6', its ascending 

 branch ; 6", its descending branch ; 7, 7', internal 

 circumflex ; 8, superior perforating ; 8', second 

 perforating ; 9, 9, muscular branches of femoral 

 artery ; 9', anastornotic branch ; 10, superior, and 

 10', inferior internal articular of popliteal. 



from which it is prolonged (9 10 mm.), 

 but at a distance of from one to two 

 inches below Poupart's ligament it be- 

 comes suddenly smaller (i) in consequence 



of its giving off a large branch, the deep femoral artery, for the supply of the muscles 

 of the thigh. The short portion of the vessel above the origin of its deep branch is 

 frequently referred to as the common femoral artery, which is then described as 

 dividing into the superficial femoral (the continuation of the trunk) and the deep 

 femoral arteries.
