INFERIOR EXTREMITY 



Circumflex Artery). This is the largest branch which 

 proceeds from the profunda femoris artery. It arises near 

 the origin of the latter from the femoral artery, and runs 

 laterally, between the divisions of the femoral nerve and under 

 cover of the sartorius and rectus femoris muscles. It ends by 

 dividing into ascending, transverse, and descending branches. 

 The ascending branch reaches the dorsum ilii by passing 



M. rectus femoris (straight head of origin) 



M. rectus femoris (reflected head of origin)

FIG. 74. Muscle- Attachments to the Lateral Surface of the Pubis and Ischium, 



proximally under cover of the tensor fasciae latae. Its terminal 

 twigs anastomose with the superior glutaeal artery. The trans- 

 verse branch is of small size. It passes to the deep surface of 

 the vastus lateralis, reaches the posterior part of the thigh, 

 and inosculates with the medial circumflex artery and the first 

 perforating artery. The descending branch gives twigs to the 

 vastus intermedius and rectus femoris, and one long branch, 

 which may be traced distally, amid the fibres of the vastus 

 lateralis, to the knee, where it anastomoses with the lateral 

 superior genicular artery.
