MYOLOGY 



tarsophalangeal ligaments of the third, fourth, and fifth toes (sometimes only 

 from the third and fourth), and from the transverse ligament of the metatarsus. 

 It is inserted into the lateral side of the base of the first phalanx of the great toe, 

 its fibers blending with the tendon of insertion of the oblique head.

Variations. Slips to the base of the first phalanx of the second toe. Opponens hallucis, occasional 

 slips from the adductor to the metatarsal bone of the great toe. 



The Abductor, Flexor brevis, and Adductor of the great toe, like the similar 

 muscles of the thumb, give off, at their insertions, fibrous expansions to blend 

 with the tendons of the Extensor digitorum longus. 



The Flexor digit! quinti brevis (Flexor brevis minimi digiti) lies under the 

 metatarsal bone of the little toe, and resembles one of the Interossei. It arises 

 from the base of the fifth metatarsal bone, and from the sheath of the Peronseus 

 longus; its tendon is inserted into the lateral side of the base of the first phalanx 

 of the fifth toe. Occasionally a few of the deeper fibers are inserted into the 

 lateral part of the distal half of the fifth metatarsal bone; these are described by 

 some as a distinct muscle, the Opponens digiti quinti.
