M. extensor digitorum longus ( fig. 17 )

ORIGIN: From the anterior surface of the lateral epicondyle of the femur.

INSERTION: Via four tendons on the dorsal surfaces of the distal phalanges of digits II– V: the most superficial tendon goes to digit II, the next to digit III, the next to digit IV, and the deepest to digit V.

REMARKS: This muscle has the same general form in Condylura , Desmana , Galemys , Parascalops , Scalopus , Scapanus , Talpa , and Uropsilus . In Neurotrichus , Scaptonyx , and Urotrichus , there is an additional head of origin from the anterior surface of the lateral process of the fibula.
