tem·po·ra·lis mus·cle

(tem-pŏr-ālis mŭsĕl)
Origin, temporal fossa; insertion, coronoid process of mandible and anterior border of ramus; action, elevates mandible (closes jaw); its posterior, nearly horizontally-oriented fibers are the primary retractors of the protruded mandible; nerve supply, deep temporal branches of mandibular division of trigeminal.
Synonym(s): musculus temporalis [TA] , temporal muscle.
