According to my notes - taken from gray's - these are the following actions I have for masseter m. There was no mention of ipsilateral abduction. From its O/I I can't see it abd. Maybe Dr. Evey can comment.
Action: Elevates the mandible (to close the teeth), protrudes the mandible, deep fibers retract the mandible
Origin: Maxillary process of the zygomatic bone, anteroinferior border of the zygomatic arch
Insertion: Angle of the mandible and the iposterolateral ramus of the mandible
