The Muscles of Mastication - Attachments - TeachMeAnatomy
2024年10月1日 · The muscles of mastication are associated with movements of the jaw (temporomandibular joint). There are four muscles: Masseter; Temporalis; Medial pterygoid; Lateral pterygoid; The muscles of mastication develop from the first pharyngeal arch. They are therefore innervated by a branch of the trigeminal nerve (CN V), the mandibular nerve.

Muscles of mastication - Wikipedia
The four classical muscles of mastication elevate the mandible (closing the jaw) and move it forward/backward and laterally, facilitating biting and chewing. Other muscles are responsible for opening the jaw, namely the geniohyoid, mylohyoid, and digastric muscles (the lateral pterygoid may play a role).
