Anterior Aspect. The following nerves are 

 found in the superficial fascia of the anterior as- 

 pect of the leg, viz. : The internal or long saphe- 

 nous, along the inner side, with branches of the 

 external popliteal on the outer side, above, and of the 

 musculo-cutaneous on the same side, below. The latter 

 nerve, i.e., the musclo-cutaneous, pierces the deep fascia 

 to become cutaneous, about the junction of the middle and 

 lower thirds of the leg. The superficial veins on the an- 

 terior aspect of the leg, are the long saphenous vein, with 

 its branches. 



The Muscles of the anterior tibial region are: The 

 tibialis anticus. From the outer tuberosity of the tibia, the 

 upper two-thirds of the external surface of the bone and 

 from the interosseous membrane ; into the inner and under 

 surfaces of the internal cuneiform and the base of the first 

 metatarsal. 



Action. It flexes the ankle joint, draws up the inner 

 border of the foot, i.e., inverts the sole, and adducts the 

 front part of the foot. The two latter movements take 

 place at the calcaneo-astragaloid and the medio-tarsal 

 joints. The flexing action of this muscle is seen in the act 

 of walking, since it is this muscle that lifts up the front of 

 the foot, so as to allow the toes to clear the ground when 

 the leg swings forward. Extensor proprius hallucis. 

 From the middle two-fourths of the anterior surface of
