given off from the anterior division of the femoral n. into the 

 thigh. 



12. Saphenous (great-, long-, internal saphenous) n.: Con- 

 tinuation of the posterior division of the femoral ; to medial side 

 of limb and ankle, primarily cutaneous. This nerve lies along 

 the craniomedial side of the femoral artery from the inguinal 

 Hgament to the origin of the saphenous artery (24) which it 

 follows closely until it is lost in the crural fascia, or medial 

 region of the tarsus. 



13. Sciatic (ischiadicus; great sciatic) n.: Mainly L.VII 

 and S.I; general cutaneous; sends branches to the muscles 

 caudad of the femur and passes along the caudal side of the 

 femur to near the popliteal space where its component halves 

 separate to form the common peroneal n. (14) and the tibial n. 

 (15) which send branches to various muscles of the leg, foot, 

 toes, and integument. 



14. Common peroneal (external popliteal, peroneal) n.: 

 Lateral branch of sciatic; to tibialis anterior and extensor com- 

 munis digitorum mm., dorsum of foot, skin, and toes. 



15. Tibial (internal popliteal) n.: Medial branch of sci- 

 atic; along the calf under the soleus muscle to sole of foot and 

 toes; gives off numerous muscular and cutaneous branches. It 

 is the medial half of the sciatic and mediad of the os calcis it 

 becomes the posterior tibial. 



16. Posterior femoral cutaneous (small sciatic) n.: S.II 

 and S.III mainly; to skin, adductores and biceps mm. and other 

 structures in the caudolateral region of the thigh. 



D. ARTERIES OF THE LEG AND FOOT 



(Nos. 26-29) 



The arteries of this region are branches of the popliteal 

 (25) and the saphenous (24). Method: The remaining skin 

 should be removed at this time and not even a hair should be 

 left attached to the base of a toe nail. At the end of the 

 laboratory period the foot and crus should be wrapped in a small
