120 TOPOGRAPHICAL ANATOMY OF 



M. rectus femoris.—The rectus femoris muscle is the middle 

 member of the quadriceps group, and arises by two short tendons from 

 depressions on the ilium just in front of the acetabulum : there is a 

 mucous (synovial) bursa between the lateral tendon and the ilium. 

 Its insertion is into the patella along with the other parts of the 

 quadriceps.

M. CAPSULAEis. — The capsular is a narrow, elongated strip of 

 muscle lying close against the hip joint, and running between the 

 lateral vastus and rectus femoris. Its origin is from the ilium close 

 to the lateral origin of the rectus, and its insertion is into a slight ridge 

 on the anterior surface of the proximal third of the femur.

A. CIECUMFLEXA FEMORIS LATERALIS. — The lateral circumflex artery 

 of the thigh is a branch of the obturator, and, in the present dissection, 

 appears between the ilium and the iliacus muscle. Branches are 

 furnished to the superficial and middle gluteal muscles and the tensor 

 of the fascia lata. The main continuation of the artery disappears 

 between the rectus femoris and the lateral vastus muscles, in which it 

 is expended. 



Dissection. — Cut across the sciatic nerve a short distance from the 

 greater sciatic foramen and the femoral vessels on a level with the hip 

 joint. Eemove the remains of those muscles that are attached in close 

 proximity to the hip joint, and clean the outer surface of the joint 

 capsule.
