The medial pterygoid nerve (or internal pterygoid nerve) is a branch off the mandibular nerve that innervates the medial pterygoid muscle, tensor veli palatini and tensor tympani.


The nerve to the medial pterygoid muscle is a slender branch of the mandibular nerve which enters the deep surface of the muscle; it gives off one or two filaments to the otic ganglion.

The nerve provides physical support for the otic ganglion, but is neurologically distinct.

Additionally, the tensor veli palati is innervated by a branch of the nerve to the medial pterygoid. Of the five paired skeletal muscles to the soft palate, tensor veli palati is the only muscle not innervated by the pharyngeal plexus.
