fibula; and communicating, to the lower end of the posterior 

 tibial. The anterior peroneal runs forward under the lower 

 edge of the interosseous membrane to the dorsum of the foot. 

 The posterior peroneal descends behind the outer malleolus 

 to the outer side of the heel and foot. [865] 



Internal Plantar. Running forward on the inner side of the 

 foot, between the Abductor hallucis and Flexor brevis digito- 

 rum, this joins the plantar digital branch of the dorsalis hal- 

 lucis to the inner side of the great toe. Three digital branches 

 join the princeps hallucis branch of the dorsalis pedis and the 

 two inner digital branches of the plantar arch, at the roots of 

 the inner three interdigital clefts. Its other branches are mus- 

 cular, cutaneous, and articular. [865] 



External Plantar. This runs forward and outward between 

 the Accessorius and Flexor brevis digitorum, and then between 

 the latter and the Abductor minimi digiti, to the base of the 

 fifth metatarsal. Then, as the plantar arch, it curves inward, 

 with the convexity forward, across the bases of the metatar- 

 sals to join the dorsalis pedis at the outer side of the base of 

 the first metatarsal, completing the arch. Its earlier branches 

 are muscular; cutaneous; and internal calcaneal, to the heel. 

 The branches of the arch are articular, to the tarsal joints; pos- 

 terior perforating, three in number, passing through the three 

 outer interosseous spaces between the heads of the Dorsal in- 

 terossei, to join the dorsal interosseous branches of the meta- 

 tarsal; and digital, four in number. Of the digital, the outer- 

 most runs along the outer side of the little toe ; the inner three 

 run to the bases of the three outer interdigital clefts and each 

 divides into branches for the sides of the toes ; just before di- 

 viding they may send (anterior perforating) branches to the 

 dorsal interosseous arteries. [866] 



Anterior Tibial. This runs forward between the uppermost 

 slips of the Tibialis posticus and above the upper edge of the 

 interosseous membrane. It then descends deeply along the 

 outer border of the Tibialis anticus, resting successively on the
