Etymology

In English this muscle’s name is the long muscle that bends the toes. The word flexor comes from the Latin flectere meaning “to bend.” The term digitorum is from the Latin digitus, which originally meant the “pointing thing,” a term that is similar to the Sanskrit word “dic” meaning to show or point out. Because we point with our fingers the term was applied to the fingers and then the toes. The term longus is Latin for “long” and is typically used when there is a similar muscle that has the same name but is shorter.

Origin

Posterior surface of the shaft of the tibia from below the soleal line to the level of the proximal end of the medial malleolus.

Insertion

Plantar surface of the base of the distal phalanges of the 4 small toes.

Action

Flexion of the little toes; weak plantar flexion of the ankle joint; assist in maintaining the longitudinal arches of the foot.

Nerve supply

Tibial nerve (L5, S1, and S2)

Blood supply

From proximal to distal, the muscle belly receives muscular branches from the posterior tibial and peroneal artery. The tendon of the muscle is supplied by the medial malleolar artery, lateral plantar artery, all four plantar metatarsal arteries and their terminal digital branches.

Latin

Musculus flexor digitorum longus

French
