UBERON:0001597 masseter VHOG:0000823 EHDAA2:0001067 FMA:48996 The masseter is a jaw muscle of therapsids derived from the m. adductor mandibulae externus, which originates in the adductor chamber (in the temporal fenestra) and inserts on the coronoid process and internal surface of the lower jaw.[Palaeos] musculus masseter EHDAA:10561 UMLS:C0024876 NCIT:C13074 MESH:D008406 Wikipedia:Masseter_muscle EMAPA:25135 BTO:0001755 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] The division of the adductor mandibulae in the various lines of tetrapod evolution correlates with divergences in their methods of feeding.
