The Mduclor Polticis Pedis, 



Arises, tendinous and fleshy, from the internal anterior part of 

 the large tuberosity of the os calcis; from a ligament being a 

 part of the aponeurosis of the sole of the foot extended from this 

 tuberosity to the sheath of the tendon of the tibialis posticus; 

 from the internal side of the naviculare, and from the cuneiforme 

 internum. 



It forms the internal margin of the sole of the foot, and is in- 

 serted, tendinous, into the internal sesamoid bone, and into the 

 base of the first phalanx of the great toe. 



It draws the great toe from the rest. 



The Flexor Brevis Pollicis Pedis, 



Is situated immediately at the exterior edge of the abductor 

 pollicis. It consists of two bellies, which are parallel with each 

 other, and separated by the tendon of. the flexor longus pollicis; 

 one is inseparably connected with the tendon of the abductor 

 pollicis, and the other with the adductor pollicis pedis. 



It arises, in common with the calcaneo-cuboid ligament, ten- 

 dinous, from the under part of the os calcis, just behind, its con- 

 nexion with the os cuboides, and from the under part of the ex- 

 ternal cuneiform bone. 



The internal belly is inserted, tendinous, into the internal se- 

 samoid bone, along with the tendon of the abductor pollicis, and 

 the external belly is inserted, tendinous, into the external sesa- 

 moid bone, along with the tendon of the adductor pollicis. 

 Each insertion is continued to the base of the first phalanx of 

 the great toe.

The Adductor Pollicis Pedis-, 



Is situated at the outside of the flexor brevis, and is extended 

 obliquely across the metatarsal bones. It arises, tendinous, at 

 the external part of the foot, from the calcaneo-cuboid ligament, 

 and from the roots of the second, third, and fourth metalar.sa! 

 bones...
