from the contiguous portion of the external cuneiform, and from the prolongation 

 of the tendon of the Tibialis posticus, which is attached to that bone. The muscle 

 divides in front into two portions which are inserted into the inner and outer sides 

 of the base of the first phalanx of the great toe, a sesamoid bone being developed 

 in each tendon at its insertion. The inner portion of this muscle is blended with

the Abductor hallucis previous to its insertion, the outer portion with the Adductor 

 obliquus hallucis, and the tendon of the Flexor longus hallucis lies in a groove 

 between them. 



The Adductor obliquus hallucis (caput obliquum m. adductoris hallucis} is a 

 large, thick, fleshy mass passing obliquely across the foot and occupying the hollow 

 space between the four inner metatarsal bones. It arises from the tarsal extrem- 

 ities of the second, third, and fourth metatarsal bones, and from the sheath of the 

 tendon of the Peroneus longus, and is inserted, together with the outer portion of 

 the Flexor brevis hallucis, into the outer side of the base of the first phalanx of the 

 great toe.
