1

at what vertebrae level is the larynx?

between c4-6

2

what happens at C6

larynx becomes trachea

3

where do the vocal cords attach?

between thyroid cartilage and vocal processes of arytenoid cartilages

4

space between tongue and epiglottis

vallecula

5

mucosa of larynx?

mainly resp epithelium except vocal cords( stratatfied squamous epithelium)

6

false vocal cords

superior (vestibular folds)

7

true vocal cords

inferior (vocal folds)

8

mucosa in larynx is supplied by?

vagus nerve

9

specifically what nerve supplies the superior vocal fold?

superiopr laryngeal branches of vagus

10

specifically what nerve supplies the inferior vocal fold?

recurrent laryngeal branch of vagus

11

what nerve gives both sensory and motor to larynx?

vagus

12

intrinsic muscles of larynx are supplied by?

vagus

13

which muscles tense the cartilages?

cricothyroid muscles (between thyroid and cricoid)

14

what muscles relax the cartilages?

thyro-arytenoid (pull arytenoid to thyroid)

15

which muscles adduct the cartilages?

lateral crico-arytenoid

AND

arytenoid muscles

rotate the arytenoids so vocal proccesses get closer together

16

which muscles abduct?

posterior crico-arytenoid muscles

widen rimma glottidis

17

which muscles contract during whispering?

lateral crico-arytenoids

18

which muscles contract in forced respiration?

posterior crico arytenoids

19

how to clinically test vagus?

ask them to swallow some water

20

how are oral sounds made?

soft palate tenses and moves up and directs air through mouth- most vowels and consonants are made

21

how are nasal sounds made?

soft palate tenses and moves down, directing air through nose
