THE MUSCLES AND FASCIAE 



Remove the fascia by dividing it in the same direction as the integument, excepting opposite 

 the ankle, where it should be left entire. Commence the removal of the fascia from below, 

 opposite the tendons, and detach it in the line of direction of the muscle fibres. 



The Tibialis anticus (m. tibialis anterior} is situated on the outer side of the 

 tibia; it is thick and fleshy at its upper part, tendinous below. It arises from the 

 outer tuberosity and upper two-thirds of the external surface of the shaft of the 

 tibia; from the adjoining part of the interosseous membrane; from the deep surface

of the fascia; and from the intermuscular septum between it and the Extensor 

 longus digitorum; the fibres pass vertically downward, and terminate in a tendon 

 which is apparent on the anterior surface of the muscle at the lower third of the 

 leg. After passing through the innermost compartment of the anterior annular 

 ligament, it is inserted into the inner and under surface of the internal cuneiform 

 bone and base of the metatarsal bone of the great toe. There is usually a bursa 

 (bursa subtendinea m. tibialis anterioris} between the tendon of the Tibialis anticus 

 and the internal cuneiform bone. At the upper part of the leg this muscle over- 

 laps the anterior tibial vessels and nerve.
