Study Notes
Facial Nerve
- The sensory nucleus of the facial nerve originates in the geniculate ganglion.
- The parasympathetic and sensory nuclei give rise to the nervus intermedius, a part of the facial nerve.
- The facial nerve bends and passes downward in the posterior wall of the middle ear at the genu of the facial nerve.
- The motor nucleus of the facial nerve is located in the pons.
- The facial nerve curves around the posterior belly of the digastric muscle to enter the posteromedial surface of the parotid gland.
