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.
Test your knowledge about the mandibular nerve (CN V3) and its divisions, branches, and functions. Learn about its formation and emergence from the cranium to enter the infratemporal fossa.
