M. epitrochleo­anconeus ( fig. 12 )

ORIGIN: A large superficial head from the posterior surface of the medial epicondyle,

and a small deeper head from the posterior surface of the humerus between the trochlea and the pit for the massive ligament associated with M. flexor digitorum profundus.

INSERTION: The two heads converge on the palmar side of the proximal crest of the olecranon process of the ulna.

REMARKS: This muscle has the same general form in Parascalops , Scalopus , Scapanus , and Talpa . In Condylura , Desmana , Galemys , Neurotrichus , Scaptonyx , Uropsilus , and Urotrichus , the deeper fibers of this muscle do not form a second head, and instead there is a continuous origin from the posterior surface of the medial epicondyle and from the adjacent posterior surface of the humerus.
