230 Arteria cruralis. 



The crural artery, 

 Art. cruralis, has received the 

 names of external iliac, 

 femoral and popliteal 

 in different parts of its course. 

 The external iliac ar- 

 tery passes obliquely down- 

 wards and outwards along 

 the inner border of the M. 

 ey lnf 8 r ' psoas, from the bifurcation of 

 the common iliac artery to 

 Poupart's ligament, where it 

 enters the thigh, and be- 

 comes the femoral artery. 

 The femoral artery com- 

 mences immediately behind 

 Poupart's ligament, and pas- 

 sing down the fore part and 

 inner side of the thigh, ter- 

 minates at the opening in the 

 M. adductor inagnus at the 

 junction of the middle with 

 the lower third of the thigh, 

 where it becomes the pop- 

 liteal. The popliteal 

 artery, commencing at 

 the opening in the M. adduc- 

 tor inagnus, passes obliquely 

 downwards and outwards 

 behind the knee-joint to the 

 lower border of the M. pop- 

 liteus, and there divides into 

 the anterior and poste- 

 rior tibial arteries. 



The branches of the 

 external iliac are : 



a) The inferior epi- 

 gastric, Art . ep igastric a 

 inferior. It at first descends 

 to reach Poupart's ligament, 

 and then ascends obliquely 

 inwards to the outer mar- 

 gin of the M. rectus abdo- 

 minis, and anastomoses above 

 the umbilicus with the supe- 

 rior epigastric artery from 

 the internal mammary (see 

 Fig. 548 and 570). From it 

 arise the p u b i c, Eamus ana- 

 stomoticus pubicus ; the e x- 

 t e r n a 1 spermatic to the 

 . spermatic cord and sheaths of
