114 THE MUSCLES. 



metatarsals, and approximate these. The first arises [fm') from the 

 edge of the plantar surface of the first metatarsal, and is inserted 

 into the corresponding- part of the second : the second [Un") passes 

 from this point to the third, and the third [tm"') to the fifth. 



B. 3IuSGLES OF THE DoRSAL SuRFACE. 



173. 31. flexor tarsi postenor (Ecker), (Fig. 92 F.t.). 



Dugès, péronéo-sus-astragal, n. i6i. 



This is a strong muscle, which has a narrow origin from the 

 outer side of the tibio-iibula, directly over the distal extremity, and 

 is inserted into the dorsal surface of the astragalus from the middle 

 to the distal extremity. 



Muscles of the first toe. 



174. 31. extensor longus dig. /(Fig. 92 e.l.i). 



Dugès, calcanéo-sus-métatarsien du pouce, n. i6ô. 



This lies to the outer side of and near the foregoing muscle ; it 

 arises by a long, strong head from the middle of the calcaneum, runs 

 obliquely backwards and inwards to unite with a small head which 

 arises from the common epiphysis of the astragalus and calcaneum, 

 in common with the m. extensor dig. II. The muscle so formed 

 passes into a flat tendon to be inserted into the basal phalanx of 

 the first toe. 



175. 31. extensor hrevis dig. /(Fig. 92 e.h.i). 



A small, short muscle which arises from the os naviculare and is 

 inserted into the dorsal surface of the first metatarsal. 



176. 31. abductor hrevis dig. /(Fig. 92 a.h.i). 



Dugès, ex-tarso-métatarsien du pouce, n. 168. 



This small muscle is situated near the preceding ; it arises from 

 the first bone of the supplemental toe, and is inserted into the inner 

 side of the first metatarsal. 



Muscles of the second toe. 



177. 31. extensor dig. II longiis (Fig. 93 e.1.2). 

 Dugès, calcanéo-sus-plialangien du II doigt, n. 182. 



This arises from the calcaneum, in common with the ni. extensor 

 longns of the third toe, and is inserted into the basal phalanx of the 

 second toe bv a tendon.
