Dorsal interossei

  • The dorsal interossei (also dorsal interossei muscles, latin: musculi interossei dorsales) of the foot are four muscles located in the sole of the foot between the metatarsal bones.

    The dorsal interossei muscles originate from the opposite surfaces of metatarsal bones. The dorsal interossei insert at the proximal phalanges of the second, third and fourth digits.

    The main function of the dorsal interossei muscles is to abduct the digits of the foot.
