LEG AND FOOT. 



on the sole and the ball of the little toe, and ends as the plantar 

 digital branch to the outer side of the little toe ; the other (in- 

 ternal branch) divides at the interval between the fourth and 

 fifth toes into two plantar digital branches for adjacent sides 

 of those toes, and communicates with the internal plantar. 

 The deep branch (terminal) runs inward deeply with the exter- 

 nal plantar artery, under the Accessorius and Adductor 

 obliquus hallucis, and supplies (articular branches) the tarsal 

 and tarso-metatarsal joints and (muscular branches) the Ad- 

 ductores, obliquus and transversus, hallucis, outer three Lum- 

 bricals, and all the Interossei except, sometimes, those in the 

 fourth space. [654] 



Small Sciatic. The two sural branches pierce the popliteal 

 fascia and supply the skin on the back of the leg, usually to its 

 middle, but sometimes more or less; they communicate with 

 the external saphenous. [657] 



ARTERIES. 



The popliteal divides, at the lower border of the Popliteus, 

 into the anterior and posterior tibial. A cutaneous branch (su- 

 perficial sural) descends in the midline of the calf. [863] 



Posterior Tibial. This runs downward and inward between 

 the superficial and deep muscles of the back of the leg, lying at 

 first on the outer, and then the inner side of the posterior tibial 

 nerve. Under the lower border of the internal annular liga- 

 ment, midway between the tip of the inner malleolus and 

 most prominent part of the heel, it divides into the internal 

 and external plantar. Branches; muscular; medullary, to the 

 tibia; communicating, to the lower end of the peroneal; cu- 

 taneous; internal malleolar, to the inner malleolus; and 

 peroneal. [864] 



The peroneal arises from the posterior tibial about an inch 

 below the Popliteus, descends on the fibula, and divides, about 

 an inch above the ankle-joint, into the anterior and posterior 

 peroneal. Its other branches are muscular; medullary, to the
