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]



taxon notes

In teleosts, the complex is composed of several derived muscles that attach to different parts of the highly kinetic skull.
