  • The flexor digitorum longus (also flexor digitorum longus muscle, latin: musculus flexor digitorum longus) is a deep muscle of the posterior group of the lower leg.

    The flexor digitorum longus originates from the posterior surface of the tibia, below the soleal line. The flexor digitorum longus inserts at the base of the medial and distal phalanges of the second, third, fourth and fifth toes.

    The functions of the flexor digitorum longus are flexion of the foot and flexion of the proximal, medial and distal phalanges of the four digits (II - V).
