Flashcards in The Tongue Deck (20):
1

What are the intrinsic muscles

Superior and inferior longitudinal muscles
Transverse and vertical muscles

2

What are the extrinsic muscles of the tongue

Genio glossus
Hypoglossus
Styloglossus
Palatoglossus

3

What si the movement of the genioglossus

Inferior fibres - protrude tongue
Middle fibres - depress tongue
Superior fibres - draw tio back and down

4

What are the movements of the hypoglossus

Depression and retraction of the tongue

5

What si the movement of the styloglossus

Retraction and elevation

6

What's it eh movement of the palatoglossus

Elevates the posterior aspect of the tongue

7

What supples the anterior 2/3 tongue general sensation

Trigeminal nerve
Lingual nerve from V3

8

What supplies the special sensory for the anterior 2/3 of the tongue

Facial nerve with chorda tympani

9

What does the glossopharyngel supply for the tongue

Posterior 1/3 taste and touch sensation

10

What drains the tongue supply

Lingual vein

11

What supplies the tongue with arterial supply

Lingual artery and bit of facial artery (tonsilar artery)

12

What si the longitudinal sulcus down the midline of the tongue called

Median sulcus

13

What si the transverse line at the posterior aspect of the tongue

Sulcus terminalis

14

What an the foramen caecum

Where the median sulcus meets the transverse terminalis
Forming a pit

15

What's it the structure that the hypoglossal nerve interacts with to supply the ,is less of the tongue

Ansa cervicalis

16

What si the odd extrinsic muscle

Palatoglossus which is innervated by vagus

17

The Ansa cervicalis consists of

C1,2,3
Hypoglossal branch

18

What else does the Ansa cervicalis innervate

Motor to genio hyoid - elevate hyoid
Thyrohyoid - depress hyoid
C3 involved which supply omohyoid sterenothyroid and sterenohyoid

19

How do u clinically test the hypoglossal nevre

Ask pt to stick tongue out
Should stick out midline
If points to a side that means there is damage at that hypoglossal nerve

20

What is want by intrinsic muscles

They only attach from the tongue and in the tongue
