THE NERVOUS SYSTEM 



The terminal branches form two groups, the superficial and the deep. 

 The superficial terminal branches are two muscular branches, the nerve to 

 the pectmeus, and the nerve to thesartorius, and two anterior cutaneous branches.

The nerve to the pectmeus pas.sc.s medially and downward txihind the femoral sheath and in 

 tront ot the psoas to the anterior surface of the i)cctiiieus, in which it terminates. 



Hhe nerve to the sartorius accompanies the middle cutaneous nerve; it leaves the latter 

 nerve above the sartorms and ends in the upper part of the muscle.
