4 LOWER EXTREMITY. 



inches above articulation, inwards, beneath tendons ramify- 

 ing upon inner malleolus, anas, with branches from posterior 

 tibia and internal plantar. External, outwards beneath ten- 

 dons, supplying outer malleolus, anas, with anterior peroneal, 

 and tarsea branch of dorsalis pedis. 



DOESA'LIS lE'DIS: (4 branches) ; from bend of ankle to ist 

 interosseous space, there dividing into communicating and 

 dorsalis hallucis. Venae comites; anterior tibial nerve lies on 

 outer side. Tar'sea I arises over scaphoid, passing outwards 

 beneath extensor brevis digitorum, supplying that muscle and 

 tarsal articulations ; anas, metatarsal, external malleolar, pe- 

 roneal, and external plantar. Metatar'sea: outwards over 

 metatarsal heads, giving off 3 interos'sece branches which pass 

 forwards to clefts of the 3 outer toes, there dividing to supply 

 adjacent sides of the toes, and outer side of little toe. Anas. 

 with tarsea and external plantar; the 3 interosseous, each, 

 receive a posterior perforating branch from plantar arch near 

 their origin, and each a branch from anterior perforating of 

 digital near the toe-clefts. Dorsa'lis hal.n'cis : forwards along 

 outer border ist metatarsus to ist toe-ciel't, there dividing to 

 supply inner side of big toe, and the adjacent sides of big and 

 ad toes. Commn'mcana : dips down into sole, anas, with external 

 plantar to form pUniar arch, there dividing to supply toes 

 same as dorsalis hallucis. 



TIBIA'LIS POSTE'EIOS : (5 brs.); from lower border popliteus, 

 parallel inner border tendo Achillis, to fossa between inner 

 ankle and heel, there dividing into the plantar arteries. Has 

 venae comites; nerve to the outside for the lower % of its 

 course. Peronse'a: from i inch below popliteus, obliquely out- 

 wards to fibula, descending along inner border of it to outer 

 ankle, supplying contiguous structures, anas, with external 

 malleolar, tarsal, and external plantar. Ante'rior peron&'a, 

 given off 2 inches above ankle, piercing interosseous mem- 

 brane, passes down to front of outer ankle and tarsus, sup- 

 plying adjacent structures, anas, with tarsal and external 

 malleolar. Nutri'tia, to fibula. Muscula'res, to fibular mus- 

 cles. Nutri'ta: near origin of posterior tibia, being largest of 

 its kind in the body; enters tibia just below oblique line. 

 Mnscula'res : to soleus and deep muscles. C.mmu'nicans : trans- 

 versly across tibia 2 inches above its inferior extremity to 

 anas, with peroneal. Calca'nes interna'les : several branches 

 arising just before division of posterior tibial, supplying fat 

 and integument about heel, and muscles of inner side of foot* 

 anas* with peroneal, internal malleolar.
