Nerve: Parotid plexus
Plan of the facial and intermediate nerves and their communication with other nerves. (Branches of facial nerve visible at bottom center.)
The nerves of the scalp, face, and side of neck. (Parotid plexus not labeled, but visible near ear.)

The pes anserinus ("goose's foot") is the term for the branch point of the facial nerve (extratemporal) after it leaves the stylomastoid foramen. It is also known as the "parotid plexus".

This division takes place within the parotid gland.

Commonly, it divides into the temporozygomatic and cervicofacial branches (several variations).
