M. mandibulo­auricularis

ORIGIN: From the dorsal margin of the angular process, just dorsal to M. pterygoideus internus .

INSERTION: Along the anteromedial surface of the auditory tube.

REMARKS: Similar in Condylura , Desmana , Galemys , Neurotrichus , Parascalops , Scaptonyx , Uropsilus , and Urotrichus . Present in Talpa , but it originates from the anterior surface of the auditory bulla directly

anterior to the meatus and from a connective tissue sheet that runs from the bulla to the posterior margin of the mandible. This muscle is greatly reduced or absent in Scalopus and Scapanus .
