M. zygomaticus major ( figs. 5 and 7 )

ORIGIN: From a small ridge just posterior to the base of the zygomatic arch.

INSERTION: Via a long tendon on the ventral surface of the nasal cartilage. This tendon runs along the upper lip just above the toothrow, around the tip of the skull, and up the ventral midline of the snout tip to the insertion.

REMARKS: This muscle has the same general form in Condylura , Desmana , Neurotrichus , Parascalops , Scalopus , Scapanus , Scaptonyx , Talpa , Uropsilus , and Urotrichus . In Desmana , this muscle originates from a prominent fossa at the base of the zygomatic arch.
