Anatomical illustrations of the origin and course of the nerves involved in the swallowing process and the muscles they innervate.
The trigeminal nerve is the fifth cranial nerve (N. V) and innervates the mylohyoideus, digastricus anterior, temporal, masseter, pterygoid medial and lateral muscles, tensor tympani, tensor veli palatini, the teeth of the mandible, the posterior part of the tongue, and the lower lip.
The facial nerve is the seventh cranial nerve (N. VII) and innervates the orbicularis oris muscle, buccinator muscle, stylohyoid muscle, and digastricus posterior muscle.
The hypoglossal nerve is the 12th cranial nerve (N. XII) and innervates M. styloglossus , M. genioglossus, M. hyoglossus and the tongue (glossus).
The spinal nerves C1, C2 and C3 also innervate muscles involved in the swallowing process. Specifically, the omohyoid, thyrohyoid, sternohyoid, and sternothyroid muscles.
The illustrations are based on existing illustrations by Heike Blum.
