TOPOGRAPHICAL ANATOMY OF 



rounded tendon of the flexor digitorum longus, and, about the same 

 level, also by a relatively slender caput tendineum arising from the 

 ligaments of the plantar aspect of the tarsus. From this point 

 onwards the tendon is disposed and terminates in a manner comparable 

 to that of the deep flexor tendon of the thoracic limb (q.v.).

muscles are the same in number and disposition as the like-named 

 structures of the metacarpus. 



Nerves of the metatarsus and digit. — At the distal end of the 

 leg the tibial nerve divides into the medial and lateral plantar nerves 

 (n. plantaris medialis; n. plantaris lateralis). These, at first, lie close 

 together on the surface of the combined tendon of the flexor hallucis 

 longus and tibialis posterior; but, before the metatarsus is reached, 

 the lateral nerve passes obliquely between the superficial and deep 

 flexor tendons, and thus arrives at the lateral border of the deep 

 tendon. The medial and lateral nerves follow the medial and lateral
