116 THE MUSCLES. 



Muscles of the fourth toe. 



181. M. extensor longus dig. IV (Fig. 93 e.l.^]. 

 Duges, p&roneo-sus-phalangien du IV, n. 178. 



A narrow muscle arising in common with the flexor tarsi inf., 

 but external to it. It is inserted into the tendinous expansion on 

 the dorsum of the toe. 



182. MM. extensores dig. IV breves (Fig. 93 e.b.4 and e.b. 4'). 



Duges, calcaneo-sus-phalangien and sus-calcaneo-phalanginien, n. 179 

 and 198. 



These two small muscles arise from the calcaneum : one is in- 

 serted into the basal phalanx, the other, by means of a long 

 thin tendon, passes along with the tendon of the corresponding 

 m. interossens to the second phalanx, to which it is attached. 



Muscles of the fifth toe. 



183. M. extensor dig. V longus (Fig. 93 <?./-5). 

 Duges, calcaneVsus-metatarsien, n. 165. 



A strong muscle which covers almost the whole length of the 

 calcaneum ; it arises from the anterior extremity of this bone, runs 

 backwards to the outer side of the dorsum of the foot, and is 

 attached to the outer surface of the fifth metatarsal. 



184. M. extensor dig. V brevis (Fig. 93 e.b.$). 



Duges, calcaneo-sus-phalangien du V, n. 1 80. 



This is a long thin muscle, which, together with the muscle last 

 described, arises from the calcaneum and is inserted into the basal 

 phalanx of the fifth toe. 



185. M. abductor dig. V brevis (Fig. 93 2.10). 



This, the last m. interosseus, arises from the outer side of the 

 fifth metatarsal, and is inserted into the hinder extremity of the 

 second phalanx of the same toe. 



186 to 195. MM. interossei clorsales (Fig. 93 i.i to ^.10). 



First toe. 



(i) The analogue of the first m. interossens is the m. abductor 

 brevis dig. I (a.b.i}. 



(3) The second m. interossens (2.2) arises from the outer side of 

 the first metatarsal, and is inserted into the outer surface of the 

 second phalanx of the same toe, dorsally to the m. opponent and 

 flexor brevis dig. T.
