Lumbricals

  • The lumbricals (also lumbrical muscles, latin: musculi lumbricales) of the foot are four small muscles of the sole of the foot.

    The lumbrical muscles arise from the tendon of the flexor digitorum longus and insert at the proximal phalanges of the second to fifth digits.

    The lumbricals play role in the flexion of the proximal phalanges and extension of the medial and distal phalanges of the second to fifth toe.
