Sensory innervation of the temporomandibular joint is provided by the auriculotemporal nerve and the masseteric nerve [8]: 412 (both branches of mandibular nerve (CN V 3) which is in turn a branch of the trigeminal nerve (CN V).
The auriculotemporal nerve is a sensory branch of the mandibular nerve (CN V 3) that runs with the superficial temporal artery and vein, and provides sensory innervation to parts of the external ear, scalp, and temporomandibular joint. The nerve also conveys post-ganglionic parasympathetic fibres from the otic ganglion to the parotid gland. [1]
The masseteric nerve is a nerve of the face. It is a branch of the mandibular nerve (CN V 3). It passes through the mandibular notch to reach masseter muscle. It provides motor innervation the masseter muscle, and sensory innervation to the temporomandibular joint.
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.
In neuroanatomy, the trigeminal nerve (lit. triplet nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.
The deep temporal nerves provide motor innervation to the temporalis muscle. The deep temporal nerves also have articular branches which provide a minor contribution to the innervation of the temporomandibular joint .
The inferior alveolar nerves supply sensation to the lower teeth, [2]: 519 and, via the mental nerve, sensation to the chin and lower lip. [citation needed] The mylohyoid nerve is a motor nerve supplying the mylohyoid and the anterior belly of the digastric. [citation needed] [contradictory]
