Oral Cavity Cbc Anatomy Block Ii Unit Iii

Front 1

Arterial supply of palatine tonsil

Back 1

Tonsilar artery from facial artery

Front 2

Mucus membrane of oral cavity

Back 2

CN IX (Glossopharyngeal)

Front 3

Innervation to the lips

Back 3

Upper lip (V2- infra orbital)
Lower lip (V3- mental, buccal)

Front 4

Cheek
-Skin innervation
-Muscle and innervation
-Mucous membrane innervation

Back 4

Skin= V2 infraorbital and V3 buccal
Muscle = buccinator (V3 buccal branch)
Mucous membrane = V3 -buccal branch

Front 5

Innervation of upper teeth and gums

Back 5

V2 (posterior and superior alveolar) (superior alveolar enters in infraorbital canal

Greater palatine nerve, nasopalatine nerve
NGreater palatine nerve

Front 6

Innervation of lower gums and teeth?

Back 6

Lingual nerve
Inferior alveolar (V3)
Buccal nerve
Mental nerve

Front 7

Upper and lower vestibular gums

Back 7

Upper=infraorbital
Lower=mental

Front 8

Lingual frenulum

Back 8

Part of tongue that attaches to the floor of the oral cavity

Front 9

Types of lingual papillae, where they are located and what they do

Back 9

Filiform papillae- most numerous, no taste buds, cover all of the dorsum of the tongue (thread like)

Fungiform papillae- club-shaped, do contain taste buds

Vallate papillae- 8-12 in number, larger papillae, toward posterior aspect of body, multiple taste buds

Follate-ridges- Occur on lateral aspect of tongue

Front 10

Sulcus terminalis

Back 10

Fusion of posterior 1/3 and anterior 2/3 of tongue from bracheophargyngeal eminence meets with tongue buds.

Front 11

Foramen cecum

Back 11

Where thyroglossal duct was (thyroid descends through here)

Front 12

Lingual tonsil

Back 12

located on the posterior 1/3 of the tongue (behing sulcus terminalis)

Front 13

Vallate papillae innervation

Back 13

Glossopharyngeal nerve

Front 14

Taste

Back 14

Vagus = taste in area of epiglottis
Glossopharyngeal = taste in posterior 1/3 of tongue
Facial = taste from the anterior 2/3 of tongue

Front 15

Sensory to tongue

Back 15
