There are four muscles that comprise the muscles of mastication, including masseter, temporalis, lateral pterygoid and medial pterygoid.¹. This article will explore the origin, insertion, action, innervation and blood supply of the 2021-04-08 · Medial pterygoid muscle is located in the infratemporal fossa lying deep to masseter and temporalis muscles and medial to lateral pterygoid muscle.. The outer surface of the muscle lies against the inner surface of mandible, from which it is separated by the lateral pterygoid muscle, sphenomandibular ligament, maxillary artery, mandibular nerve and its lingual and inferior alveolar branches. The action of closing the jaw is performed by the upward pull of the temporalis, the masseter, and and the medial pterygoid muscles. Opening of the jaw is brought about partly by the force of gravity, partly by the forward pull of the lateral pterygoid muscles, and partly by the backward and downward pull of muscles we’ll see in a minute, that act by way of the hyoid bone. 2017-07-26 · The frontalis muscle lays directly atop the temporalis muscle, the largest muscle in the head, which raises the mandible and contributes to the action of closing the mouth and chewing.
