Study Notes
Anatomy of the Salivary Gland
- The parotid gland has a parotid sheath containing parotid lymph nodes.
- The five terminal branches of the facial nerve emerge from the anterior border of the gland, radiating outward like a goose's foot.
- The facial nerve passes over the lateral surface of the masseter muscle, about one fingerbreadth below the zygomatic arch.
- The parotid gland may become acutely inflamed due to retrograde bacterial infection from the mouth via the parotid duct.
- Parotid gland infections can lead to the growth of parasympathetic secretomotor fibers in the auriculotemporal nerve, which join the distal end of the great auricular nerve during the healing process.
