external definition

Is a mandibular muscle that forms along the palatoquadrates and inserts on Meckel's cartilages and functions in jaw closing[ZFA:0007049].

adductor mandibulae complex, levator mandibulae

homology notes

The division of the adductor mandibulae in the various lines of tetrapod evolution correlates with divergences in their methods of feeding. (...) As the jaws become stronger and their movements more complex in the line of evolution toward mammals, the adductor complex becomes divided into several distinct muscles (temporalis, masseter, pterygoideus, tensor tympani, tensor veli palati).[well established][VHOG]
