MYOLOGY. 75 



and from the cuboid and external cuneiform bone, and passing forwards is 

 divided into two tendons inserted into the sesamoid bones beneath the first 

 phalanx of the great toe. It flexes the first joint of the great toe, and 

 approximates this toe to the others. 



Adductor ■pollicis arises from the calcaneo-cuboid ligament and from the 

 base of the second, third, and fourth metatarsal bones ; it is inserted into 

 the external sesamoid bone. It dra\vs the great toe outwards towards the 

 others, and flexes it so as to bring it beneath them. 



Transversalis pedis arises by distinct slips from the anterior extremities 

 of the four external metatarsal bones. It is inserted into the external 

 sesamoid bone of the great toe along with the last mentioned. It approxi- 

 mates the toes and contracts the arch of the foot. 



Flexor hrevis minimi digiti arises from the cuboid and fifth metatarsal 

 bones, and is inserted into the inner side of the base of the first phalanx of 

 the little toe, which it serves to flex and adduct. 



The interossei muscles are seven in number ; three are seen on the sole 

 and four on the dorsum. The inferior are adductor medii digiti, adductor 

 quarti digiti, and adductor minimi digiti. Thej arise from between the 

 metatarsal bones of the four external toes, and are inserted into the inner 

 side of the base of the first phalanx of the three lesser toes. The superior 

 interossei are all abductors, viz. internus digiti secundi, externus digiti secundi, 

 abductor digiti medii, and abductor digiti qriarti.
