Maxillary nerve

Question 1

Nerves

Answer 1

Teeth, jaws + face are supplied by the 5th cranial nerve (out of 12) the tringeminal nerve one for left + one for right side
it splits into three divisions: ophthalmic, maxillary + mandible nerves

Question 2

Maxillary nerve

Answer 2

emerges from the base of the brain, leaves skull through the foramen rotundum + passes forward through the floor of the orbit (eye socket)

Question 3

Before entering the orbit

Answer 3

it gives off its posterior superior alveolar + palatine branches

Question 4

Within the orbit

Answer 4

it gives off the middle + anterior superior alveolar nerves

Question 5

Comes from the orbit through

Answer 5

the infra-orbital foramen on the front of the maxilla to supply skin + mucosa membrane of the lower eyelid, cheek + upper lip

Question 6

Posterior superior alveolar nerve

Answer 6

enters the back of the maxilla to reach its destination

Question 7

The greater palatine nerve

Answer 7

also passes through the back of the maxilla + reaches the surface of the hard palate through the greater palatine foramen, opposite the third molar tooth

Question 8

The nasopalatine nerve

Answer 8

passes through the floor of the nasal cavity to reach the surface of the palate through the incisive foramen behind the central incisors

Question 9

The anterior + middle superior dental nerves

Answer 9

branch off from the maxillary nerve in the floor of the orbit. they pass down inside the maxilla, in the walls of the maxillary sinus, to reach the teeth.

Question 10

The sensory nerve impulses

Answer 10

from the upper teeth + their surrounding soft tissue structures pass from the nerve endings back along these nerve pathways to the maxillary nerve trunk, + then enter the skull + join the other two divisions to form trigeminal nerve trunk, which then enters the brain itself

Question 11

It supplies:

Answer 11

the skin of posterior part of the side of nose, lower eyelid, cheek, upper lip, lateral side of orbit + has 3 branches:

Question 12

1. Infraorbital nerve:

Answer 12

is a direct continuation of maxillary nerve. leaves orbit via infraorbital foramen. it gives numerous small branches that supply skin of lower eyelid, cheek + side of nose + upper lip

Question 13

2. Zygomaticofacial nerve:

Answer 13

passes onto face via small foramen on lateral side of zygomatic bone to supply skin over the cheek

Question 14

3. Zygomaticotemporal:

Answer 14

passes through a small foramen on the posterior part of zygomatic bone to supply skin of temple.
