muscle. Its subsequent course will be followed in the dissection of 

 the leg. 



While in the thigh, the tibial nerve gives off two branches. (1) The 

 proximal muscular ramus (ramus muscularis proximalis) is large, 

 and leaves the tibial close to the level of the hip joint. It very soon 

 divides into nerves that are distributed to the biceps, semimembranosus,

and semitendinosus muscles. (2) The posterior cutaneous sural ^ nerve 

 (n. cutaneus suras posterior (medialis)) is a small branch that leaves 

 the tibial just before it passes between the two heads of the gastro- 

 cnemius muscle. Leaving the thigh by following the lateral face of 

 the gastrocnemius, the sural nerve will be examined later in the 

 dissection of the leg.
