M. digastricus , venter posterior ( fig. 6 )

The anterior portion of the digastric is discussed with the muscles of the Trigeminal Field.

ORIGIN: From the ventral base of the skull between the occipital condyle and the stylomastoid foramen, from the surface of the un­

derlying M. jugulohyoideus , and from the stylohyal cartilage.

INSERTION: In a tendinous inscription into the anterior belly of the digastric.

REMARKS: This muscle has the same general form in Condylura , Desmana , Neurotrichus , Parascalops , Scaptonyx , Uropsilus , and Urotrichus . The stylohyal portion is especially large in Condylura . Scalopus , Scapanus , and Talpa lack fibers from the stylohyal cartilage.
