What is the auriculotemporal nerve?
What is the auriculotemporal nerve?
A branch of the mandibular nerve (CN V3) that carries sensory information from the skin of the auricle (outer ear) and the external auditory meatus, as well as parasympathetic fibers to the parotid salivary gland.
What is the mandibular nerve (CN V3)?
What is the mandibular nerve (CN V3)?
A division of the trigeminal nerve (CN V) that carries motor fibers to the muscles of mastication (chewing) and provides sensory innervation to the lower face and teeth.
What is the lingual nerve?
What is the lingual nerve?
A branch of the mandibular nerve that provides sensory innervation to the anterior two-thirds of the tongue (taste and touch) and the floor of the mouth.

Study Notes
Nerve Functions and Pathways
- The auriculotemporal nerve supplies the skin of the auricle, the external auditory meatus, and conveys postganglionic parasympathetic secretomotor fibers from the otic ganglion to the parotid salivary gland.
Mandibular Nerve
- The mandibular nerve emerges from the foramen ovale to enter the infratemporal fossa.
- It supplies motor fibers to the muscles of mastication.
Lingual Nerve
- The lingual nerve descends in front of and medial to the inferior alveolar nerve, enters the mouth, and runs forward on the side of the tongue.
- It supplies the mucous membrane of the anterior two thirds of the tongue and the floor of the mouth.
Trigeminal Nerve (CN V)
- The mandibular division (V3) carries motor fibers.
- The mandibular division (V3) supplies motor fibers to the muscles of mastication.
