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
