M. sphincter colli profundus, pars intermedia dorsalis ( fig. 3 )

ORIGIN: From the dorsal midline between the ear and the eye.

INSERTION: On the surface of M. platysma myoides .

REMARKS: This muscle has the same general form in Condylura , Desmana , Neurotrichus , Parascalops , Scalopus , Scapanus , Scaptonyx , Talpa , Uropsilus , and Urotrichus . The fibers of this muscle appear to cross through M. platysma myoides to form the pars intermedia ventralis. The anteriormost fibers are somewhat superficial to the remainder of the muscle and were distinguished by Meinertz (1978a) as a separate M. frontolabialis.
