The Flexor<unk><unk>  arises, by a pointed tendinous process, from the medial part of the under surface of the cuboid bone, from the contiguous portion of the third cuneiform, and from the prolongation of the tendon of the Tibialis posterior which is attached to that bone.
It divides in front into two portions, which are inserted into the medial and lateral sides of the base of the first phalanx of the great toe, a sesamoid bone being present in each tendon at its insertion.
The medial portion is blended with the Abductor<unk>  previous to its insertion; the lateral portion with the Adductor<unk> ; the tendon of the Flexor<unk>  longus lies in a groove between them; the lateral portion is sometimes described as the first Interosseous plantaris.
