Extensor digitorum brevis

  • The extensor digitorum brevis (also extensor digitorum brevis muscle, latin: musculus extensor digitorum brevis) is a muscle of the upper surface (dorsum) of the foot.

    The extensor digitorum brevis originates from the superior and lateral surface of the calcaneus. The fibers of the extensor digitorum brevis pass forwards and insert into the tendon of the extensor digitorum longus.

    The main function of the extensor digitorum brevis is to extend the second, third and fourth digits of the foot.
