described nerve, an equally large branch lies just entad and 

 dips between the M. extensor digitorum longus and the M. 

 peroneus tertius. Ten mm. peripherad of its origin the nerve 

 bifurcates, the anterior tibial artery (Fig. A.) occupying the 

 angle between the branches. The cephalic branch (Fig. cc.) 

 innerves the M. extensor longus digitorum; the caudal branch 

 (Fig. ca.) lies entad of the anterior tibial artery and accom- 

 panies the artery to the dorsum of the foot. Entad of the 

 groove a ramus is given to the tarsal ligament and the origin 

 fibres of the M. extensor brevis. The terminal filaments join 

 in the plexus to the integument of the dorsum of the foot 

 and toes. 



N. TIBIALIS ANTICUS. 



This branch (Fig. Tib. a., and m.) of the peroneal is 

 given ofl' between the origin of the musculo-cutaneous 

 nerve and the bifurcation of the peroneal; it can be traced 

 30-40 mm. in the substance of the M. tibialis anticus, 

 and sends a ramus peripherad to the M. extensor longus 

 digitorum. 



N. POPLITEl S. 



The cephalic division of the great sciatic nerve crosses 

 the popliteal space and continues peripherad between the 

 heads of the M. gastrocnemius. At the proximal end of the 

 crus it gives its first branch to the ectal surface of the caudal 

 head of the M. gastrocnemius (Fig. M. gas.), and immedi- 

 ately peripherad a large ramus penetrates the same muscle 

 and is distributed to the muscle from its ental surface; a con- 

 siderable portion of this ramus perforates the gastrocnemius 

 and innerves the M. Soleus (Sol.), which is entad; from this 

 penetrating ramus rannili are given to both heads of the 

 muscle. Twenty mm. peripherad a second large branch to 

 the body of the same muscle (Fig. M. gas.), peripherad of 

 which the nerve trunk bifurcates, forming ental (Fig. dv. 

 ent.) and ectal (Fig. dv. ect.) divisions.
