1

Leaves skull via foramen rotundum and supplies upper teeth, oral cavity, skin of cheek/temporal region. And divides into different divisions at or in pterygopalatine fossa

V2

2

Supplies maxillary buccal gingiva of premolars/molars. Supplies up to MB root of 1st moose but not the MB root

Posterior superior alveolar (PSA)

3

Supplies lateral walls of nasal cavity and enters anterior palate as nasopalatine nerve via incisive foramen

Sphenopalatine

4

Multiple branches to ganglion

Pterygopalatine nerves

5

What are the 2 branches of the descending palatine

Lesser palatine and greater palatine

6

Soft palate

Lesser palatine

7

Mucosa or posterior hard palate

Greater palatine

8

Supplies skin over the cheek/temple

Zygomatic

9

Exits via infraorbital foramen, supplies skin of nose, lower eyelid, skin and mucosa of upper lip and max labial gingiva

Infraorbital

10

What are the branches of infraorbital

Middle superior alveolar and anterior superior alveolar

11

Middle superior alveolar

Premolars

12

Anterior superior alveolar

Max incisors

13

Leaves skull through foramen ovale

V3

14

What are the nerves of the V3

Buccal, lingual, inferior alveolar, auriculotemporal

15

Spreads on surface of buccinator muscle and has long buccal nerve

Buccal nerve

16

Supplies buccal mandibular gingiva up to mental foramen

Long buccal nerve

17

Largest branch of V3, sensation to floor of mouth, lingual mandibular gingiva, and anterior 2/3 of tongue. Joins chorda tympani

Lingual nerve

18

Branch of CN VII supplies submandibular/sublingual glands and also carries taste perception to anterior 2/3 of tongue

Chorda tympani

19

Serves lower teeth, mylohyoid nerve branches and supplies mylohyoid muscle, enters mandible via mandibular foramen, mental nerve branches and goes through mental foramen to supply mucosa of lip and labial gingiva in anterior mandible

Inferior alveolar nerve

20

Runs backwards to supply area above and in front of the ear

Auriculotemporal nerve

21

What are the branches of facial VII

Temporal, zygomatic, buccal, mandibular, cervical

22

Supplies platysma muscle

Cervical

23

Exists via stylomastoid foramen and travels through parotid gland. Supplies muscles of facial expression

Facial VII

24

Exits with vagus and accesory nerves through jugular foramen. Branches to stylopharyngeal muscle and constrictors of pharynx. Also a branch to the posterior 1/3 of tongue

Glossoplaryngeal IX

25

Longest, fibers to heart, lungs, kidneys, and most of the digestive tract. Also sends branches to the pharynx, larynx, and tongue

Vagus X

26

What are all of the oral cavity nerves

Trigeminal V, Facial VII, Glossopharyngeal IX, and Vagus X
