This muscle varies considerably in the modes of origin and the arrangement of its various tendons. The tendons to the second and fifth toes may be found doubled, or extra slips are given off from one or more tendons to their corresponding metatarsal bones, or to the short extensor, or to one of the interosseous muscles.

It extends between the medial process of the tuber calcanei [1] and the proximal phalanges of [citation needed] the toes. It provides some attachment to the flexor muscles of the toes. [1] Distally, the plantar fascia becomes continuous with the fibrous sheaths enveloping the flexor tendons passing to the toes.
