572. The Arteries at the Hip. 



Specimen from a child. 



Within the pelvis the obturator artery supplies the MM. iliacus, 

 obturator -interims and levator ant and sends the llamus anastomoticus to 

 the Sympliisis puljis (see Fig. 570)- 



The two most important anomalies in the origin and communi- 

 cation of the obturator and inferior epigastric arteries are shown in 

 Fig. 573 and 574. 



b) The sciatic artery, Art. iscluadica s. glutaea inferior, leaves 

 the pelvis below the M. pyriformis in company with the sciatic nerve ; 

 it supplies the external rotators of the thigh and the flexors of the leg 

 which arise from the Tiiber 'ischii. A small branch, the Art. comes N. 

 isc-Jiiadici, accompanies the sciatic nerve. 



c^ The vesical arteries, Arteriae vesicales, a superior and 

 nn inferior, very often also a in i d d 1 e. The s u p e r i o r supplies the 

 posterior wall and fundus of the bladder; the inferior the base of 

 the bladder, the Vesiculae seminalcs, the prostate gland and, in the female, 

 the vagina (see Fig. 575). In the male it also sends off the artery of 

 the Vas deferens, which passes down as far as the epididymis.
