 into the backs of the four greater toes. Use ; it extends the toes. 



Flexor Brevis Digitorum Pedis^ (Fig. 76.) — Origin, from the 

 tuberosity of the os calcis and plantar fascia. 

 Insertion, by four small tendons, which are Fig. 76. 



perforated by those of the flexor longus, into 

 the second phalanges of the four smaller toes. 



Flexor Accessarius. — Origin, from the in- 

 side of the sinuosity of the os calcis in front 

 of its tuberosities. Insertion, into the out- 

 side of the tendon of the flexor longus, at its 

 division. Use ; assists in flexion. 



Lumhricales Pedis. 'i — Origin, from the 

 tendon of the flexor longus. Insertion!, into 

 the inside of the first phalanx of each toe. 

 Use ; assist in flexion. 



Abductor PoUicis Pedis.^ — Origiti, from 

 the internal tuberosity of the os calcis, the 

 plantar fascia, and internal cuneiform bone. 

 Insertion, into the inner side of the base of 

 the first phalanx of the great toe, including 

 the internal sesamoid bone. Use ; it draws 

 this toe from the others. 



Flexor Brevis PoUicis Pedis. — It consists 

 of two bellies, which arise from the calcaneo- 

 cuboid ligament and external cuneiform bone. 

 Insertio7i, by two tendons into the base of the first phalanx of the 

 great toe,' including the sesamoid bones. Use ; it flexes this toe. 



Abductor PoUicis Pedis. — Origin, from the calcaneo-cuboid liga- 

 ment, from the bases of the second, third, and fourth metatarsal 

 bones of the lesser toes. Insertion, into the tendon of the flexor 

 brevis and external sesamoid bone. Use ; to draw this toe towards 

 the rest. 



Abductor Minimi Digiti Pedis.^ — Origin, from the outer tube- 

 rosity of the OS calcis and the metatarsal bone of the little toe. 

 Insertion, into the base of the first phalanx of the little toe. Use ; 

 it draws this toe from the others. 



Flexor Brevis Minimi Digiti Pedis. — Origin, from the calca- 

 neo-cuboid ligament, and from the fifth metatarsal bone. Insertion, 

 into the base of the first phalanx of the little toe, and into the head 

 of its metatarsal bone, tise ; it bends the little toe. 



Transversalis Pedis. — Origin, from the capsular ligaments of the
