Answer 2

Infraorbital

Zygomaticofacial

Zygomaticotemporal

Question 3

Why do scalp wounds bleed profusely?

Question 4

What cranial nerve closes your eye?

What cranial nerve opens your eye?

Answer 4

Closes: VII

Opens: III

Question 5

What are the sensory branches of the opthalmic division of the trigeminal nerve?

Answer 5

Supraorbital

Supratrochlear

Palpebral branch of the lacrimal nerve

Infratrochlear nerve

External nasal branch of the anterior ethmoidal.

Question 6

What cranial nerve supplies the muscles of mastication?

Answer 6

Mandibular branch of the trigeminal nerve V3.

Question 7

What are the functions of the sensory root of the facial nerve?

With which structures do each of these fibers travel?

Answer 7

Taste to the anterior 2/3 of the tongue.

Parasympathetics to the lacrimal gland, submandibular gland, and sublingual salivary gland (not parotid).

The fibers supplying taste to the anterior 2/3 of the tongue, as well as the parasympathetic fibers to the submandibular and sublingual salivary glands all run with the chorda tympani.

Parasympathetic fibers to the lacrimal ducts run with the greater petrosal.
