Parotid Bed

Question 1

Facial Nerve

Answer 1

Most superficial structure in the gland
Two branches:
1) Posterior auricular branch to the occipital belly
2) Motor nerve to post. belly of digastric and stylohyoid

Question 2

The junction of what two veins form the retromandibular vein?

Answer 2

Superficial temporal and maxillary

Question 3

What does the retromandibular vein then do?

Answer 3

Divides into anterior and posterior divisions

Question 4

What does the posterior division of the retromandibular vein do?

Answer 4

Joins with the posterior auricular vein to form the external jugular vein

Question 5

What does the anterior division of the retromandibular vein do?

Answer 5

Joins with the facial vein and drains into the internal jugular vein

Question 6

What happens to the external carotid artery in the parotid?

Answer 6

Terminates in the gland into two terminal branches:

1) Maxillary artery
2) Superficial temporal artery

Question 7

Sympathetic innervation of the parotid

Answer 7

From the superior cervical ganglion in the chain
Travels with the external carotid artery
Produces thick saliva

Question 8

Parasympathetic innervation of the parotid

Answer 8

The tympanic and lesser petrosal nerves of CN IX bring preganglionic to the otic ganglion
Post ganglionic go with the auriculotemporal nerve
Produces thin, watery saliva
