Detailed explanation-1: -The classification of the muscles of mastication refers to four main muscles including the masseter, temporalis, medial pterygoid, and lateral pterygoid. The actions of the muscles of mastication open and close the mouth by influencing motion on the mandible.

Detailed explanation-2: -The medial pterygoid muscle is innervated by the medial pterygoid branch of the mandibular nerve. Its principal blood supply stems from the pterygoid branches of the maxillary artery. The major functions of this muscle are elevation of the mandible and side-to-side movements when grinding and chewing.
