Produces serous saliva

Parotid duct of Stenson

Parotid glands

1

Enters the parotid gland after emerging from the stylomastoid foramen

Facial nerve (CN VII)

2

Facial nerve (CN VII) divides into:

Temporal

Zygomatic

Buccal

Mandibular

Cervical

3

Innervated the muscles of facial expression

Has no function in the parotid gland

Facial nerve (CN VII)

4

Blood supply

Branches of EXTERNAL CAROTID ARTERY

5

Venous drainage

RETROMANDIBULAR VEIN ➡️ external jugular vein

6

Postganglionic sympathetic

Secretion of thick mucus

Superior cervical ganglion

7

Travel within tympanic nerve and lesser petrosal nerve ➡️ synapse on cell bodies within the otic ganglion

PREGANGLIONIC PARASYMPATHETIC

Inferior savilary nuclesus of glossopharyngeal nerve (CN IX)

8

Leave the otic ganglion and travel with auriculotemporal nerve of trigeminal nerve (CN V) to the parotid gland

Watery secretion

POSTGANGLIONIC PARASYMPATHETIC

9

Carries postganglionic sympathetic fibers to sweat glands of the head & postganglionic parasympathetic fibers to the parotid gland

Auriculotemporal nerve of CN V
