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.
