M. flexor carpi radialis

ORIGIN: From the base of the pit for the massive ligament of M. flexor digitorum profundus at the distal end of the humerus, adjacent to the entepicondylar foramen.

INSERTION: Via a tendon that passes through a groove on the lateral side of the centrale and fans out to attach to the posteroventral margins of metacarpals II and III.

REMARKS: This muscle has the same general form in Parascalops , Scalopus , Scapanus , and Talpa . In Condylura , Desmana , Galemys , Neurotrichus , Scaptonyx , Uropsilus , and Urotrichus , this muscle inserts only on metacarpal III. Dobson (1882–1890) described this muscle as inserting on metacarpal II in Desmana , but in the specimen that I dissected it inserted on metacarpal III. Reed (1951) stated that M. flexor carpi radialis inserts on metacarpal II in Neurotrichus , but in the three specimens of this genus that I dissected it invariably inserted on metacarpal III.
