The auriculotemporal nerve arises as a posterior division of the mandibular branch of the trigeminal nerve. It innervates the temples and the temporomandibular joint. The superficial branches supply the tragus and the auricle of the ear. Its proximal trunk is located superficially just anterior to the tragus.
