M. sphincter colli superficialis ( fig. 3 )

ORIGIN: From the skin and connective tissue of the ventral midline, where the antimeres decussate.

INSERTION: On the side of the neck and on the dorsal surface of the shoulder. Fibers of M. sphincter colli superficialis appear to merge with fibers of the pars intermedia dorsalis of M. sphincter colli profundus where the two layers overlap.

REMARKS: This muscle has the same general form in Condylura , Desmana , Neurotrichus , Parascalops , Scalopus , Scapanus , Scaptonyx , Talpa , Uropsilus , and Urotrichus .
