1

How many cranial nerves does the tongue have?
Innervation-

4 cranial nerves
V3, 7, 9, 12

2

Tongue terminology

Glossal or lingual
Covered with mucosa

3

Tongue functions

Speech, mastication, degulation-swallowing

4

Tongue blood supply

Lingual artery- supplies tongue

5

The medial septum in tongue is

Paired muscle

6

The tongue is a mass of muscle covered with

Mucosa

7

Body of the tongue made up of

Ventral surface(bottom), lateral surface(side of), dorsum(top of), and apex (tip of)

8

Types of mucosa in the oral cavity

Lining, masticatory, specialized

9

Lining mucosa location

Ventral surface of tongue, floor of mouth, alveolar and buccal mucosa, soft palate.

10

Lining mucosa histology

Nonkeratinized stratified squamous epithelium. Less pronounced rete pegs

11

Lining mucosa function

Protective cushion, wimpy compared to keratinized

12

Masticatory mucosa location

Dorsal surface of tongue, hard palate, attached gingiva

13

Masticatory mucosa histology

Keratinized stratified squamous epithelium, pronounced rete pegs

14

Masticatory mucosa function

Resiliency, barrier

15

Specialized mucosa location

Dorsal and lateral surfaces of tongue with lingual papillae.

16

Specialized mucosa histology

Orthokeratinized

17

Specialized mucosa function

Taste

18

Ventral surface
Lingual frenum-

Connects tongue to floor of mouth

19

Ventral surface
Deep lingual vein-

Blue(can see in some)

20

Ventral surface
Plica fimbriata-

Hair like projections

21

Ventral surface
Sublingual fold-

Area between tongue and where floor of mouth starts

22

Ventral surface
Sublingual gland-

Can't really see, produces saliva

23

Ventral surface
Sublingual caruncles

2 little holes, gland puts saliva out of these

24

Dorsal surface
Fungiform papilla-

Mushroom shape

25

Dorsal surface
Filiform papilla

Finger like projections, can collect plaque, keratinized

26

Dorsal surface
Circumvallate papilla-

Projection that forms inverted V, very far back, span evanor?

27

Dorsal surface
Foliate papilla-

Ruffles on lateral border,
Posterior on tongue

28

Dorsal surface
Lingual tonsil-

At base, lymphatic tissue behind circumvallate papilla.

29

Extrinsic tongue muscles
O:
I:

O: outside the tongue
I: inside/within tongue

30

Extrinsic tongue muscles functions

Speech, mastication, swallowing
