Muscles of Mastication [Part 1] | Origins, Insertions, Etc.

The video tutorial explains the major muscles involved in mastication, focusing on the temporalis, masseter, and the medial and lateral pterygoids. It describes the temporomandibular joint (TMJ) and the movements of the mandible. The tutorial covers the origins, insertions, and actions of these muscles, emphasizing their role in elevating and retracting the mandible. It also highlights the innervation by the mandibular nerve, differentiating these muscles from facial muscles. The video sets the stage for further exploration of the TMJ and the detailed actions of the pterygoid muscles.
