LEG AND FOOT. 



interosseous membrane, lower part of the tibia, and anterior 

 ligament of the ankle-joint; the Extensor proprius hallucis 

 tendon crosses its lower end. In front of the ankle it becomes 

 the dorsalis pedis. [867] 



Branches. Superior fibular; arising high up and ascending 

 behind the neck of the fibula. Posterior tibial recurrent; 

 arising high up and ascending in front of the Popliteus to the 

 back of the knee. Anterior tibial recurrent; arising high up 

 and ascending in front of the knee, externally. Muscular. Cu- 

 taneous. Internal malleolar; to the front of the inner malle- 

 olus. External malleolar; to the front of the external mal- 

 leolus. [868] 



Dorsalis Pedis. Running forward superficially under the 

 anterior annular ligament and along the outer side of the Ex- 

 tensor proprius hallucis tendon, this passes through the base 

 of the first interosseous space, between the heads of the first 

 Dorsal interosseous and joins the end of the external plantar, 

 completing the plantar arch. [868] 



Branches. Cutaneous. Tar sal, to the outer part of the tar- 

 sus. Metatarsal; arising low down and running outward on 

 the bases of the metatarsals, under the tendons: from it three 

 branches (dorsal interosseous) run to the three outer toe- 

 clefts, and each divides into two collateral digital branches for 

 the adjacent sides of the toes; the outer dorsal interosseous 

 sends a branch to the outer side of the little toe ; each dorsal 

 interosseous sends a branch (posterior perforating) through 

 the back part of the interosseous space, between the heads of 

 the Dorsal interosseous, to join the plantar arch, and another 

 (anterior perforating) through the front of the space to the 

 plantar digital artery. Dorsalis hallucis; running forward to 

 the innermost toe-cleft it divides into collateral dorsal digital 

 branches to the adjacent sides of the toes; it gives off a dorsal 

 digital branch to the inner side of the great toe. Princeps 

 hallucis; arising in the sole, from the termination, it runs for- 

 ward to the innermost toe-cleft and divides into collateral
