 to the lesser trochanter, 

 it divides into an ascend-

 it divides the main trunk 

 gives off (i) a super- 

 ficial branch which 

 passes medially across 

 the front of the pectineus 

 and between the ad- 

 ductors longus and 

 brevis, and (2) an arti- 

 cular branch which enters 

 the hip -joint through 

 the incisura acetabuli. 

 The terminal branches
