Fig. 657.âThe Distribution of the Trigeminal and Facial Nerves on the Face. The posterior auricular nerve communicates with the great auricular, lesser occipital, and auricular branch of the vagus nerves in its course. (iv ) In the parotid gland the facial nerve spreads out in an irregular series ot branches (plexus parotideus), indefinitely divided into a temporo-facial and a cervico- facial division. Communications occur in the substance of the gland between the main trunks and the great auricular and auriculo-temporal nerves. The temporo-facial division gives off two series of subordinate branches which radiate forwards and upwards from the parotid gland. 1 Rami Temporales.â The temporal branches are of
