The medial pterygoid muscle has functions including elevating the mandible (closing the mouth), protruding the mandible, mastication (especially for when the maxillary teeth and the mandibular teeth are close together), [1] and excursing the mandible (contralateral excursion occurs with unilateral contraction).
The medial pterygoid plate (or medial pterygoid lamina) of the sphenoid bone is a horse-shoe shaped process that arises from its underside.. It is narrower and longer than the lateral pterygoid plate and curves lateralward at its lower extremity into a hook-like process, the pterygoid hamulus, around which the tendon of the tensor veli palatini glides.
The medial pterygoid nerve supplies the medial pterygoid muscle, tensor tympani muscle, and tensor veli palatini muscle (via the nerve to tensor veli palatini). [1] The tensor veli palati muscle is the only of the five paired skeletal muscles to the soft palate not innervated by the pharyngeal plexus. [citation needed]

The medial pterygoid; The lateral pterygoid; In humans, the mandible, or lower jaw, is connected to the temporal bone of the skull via the temporomandibular joint. This is an extremely complex joint which permits movement in all planes.

The mandibular nerve immediately passes between tensor veli palatini, which is medial, and lateral pterygoid, which is lateral, and gives off a meningeal branch (nervus spinosus) and the nerve to medial pterygoid from its medial side. The nerve then divides into a small anterior division and a large posterior division.
