Muscles of mastication
After going through this study unit you will be able to:
- Name the muscles of mastication and describe their different parts.
- Describe the attachments, innervation and function of the muscles involved in chewing.
The muscles of mastication are a group of four muscles: the temporalis, masseter, medial pterygoid and lateral pterygoid. These muscles produce movements of the mandible, or lower jaw, at the temporomandibular joints, thus enabling functions such as chewing and grinding.
