The parotid plexus or plexus parotideus is the branch point of the facial nerve (extratemporal) after it leaves the stylomastoid foramen. This division takes place within the parotid gland . Branches
The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.

The parotid gland is situated laterally to the styloid process, the external carotid artery passes by its apex, the facial nerve crosses its base, and the attachment of the stylopharyngeus muscle separates it from the internal jugular vein medially. [1]
The facial canal gives passage to the facial nerve (CN VII) (hence the name). [1] [verification needed] [better source needed] Its proximal opening is at the internal auditory meatus; its distal opening is the stylomastoid foramen. In humans, the canal is approximately 3 cm long, making it the longest bony canal of a nerve in the human body.
Mandible: lower portion of the jaw; largest bone in the skull; Lacrimal bones: contains the nasolacrimal duct, which carries fluid from the surface of the eye, to the nose; Ethmoid bone: complex bone separating the nasal passages from the cranial vault; Frontal bone: creates the forehead of the horse
The zygomatic branches of the facial nerve (malar branches) are nerves of the face. They run across the zygomatic bone to the lateral angle of the orbit. Here, they supply the orbicularis oculi muscle, and join with filaments from the lacrimal nerve and the zygomaticofacial branch of the maxillary nerve (CN V 2).
It is the first branch outside of the skull. [2] This origin is close to the stylomastoid foramen. It runs upward in front of the mastoid process. It is joined by a branch from the auricular branch of the vagus nerve (CN X). It communicates with the posterior branch of the great auricular nerve, as well as with the lesser occipital nerve.
