Answer 1

wider angle in females, less angle in males

Question 2

Attaches to superior cornu

Answer 2

thyrohyoid membrane attaches here

Question 3

Attaches to inferior cornu

Answer 3

-articulates w/ cricoid cartilage

Question 4

a. Broad posterior lamina; gets large
b. Anterior arch; narrow
c. Forms complete ring; ONLY one that makes ring around

Answer 4

Cricoid cartiledge1

Question 5

Sit on top of posterior lamina. 2 of them sit there, connect to cricoid via synovial joints

Answer 5

Arytenoids

Question 6

Actions of arytenoids

Answer 6

ability to move/twist/glide→ All affects voice!

• d/t flat articular surface
• move medially and come closer together
• go anteriorly and slide forward
  
  • can twist/rotate

Question 7

Vocal Process: projects anteriorly/posteriorly or laterally?

Answer 7

Vocal Process: projects anteriorly

-vocal ligament attaches then to inside surface of thyroid cartiledge

Question 8

Muscular processes connect:

Answer 8

Posterior and lateraly: musclular process

- contracts allow it to swivel

Question 9

Where does the Corniculate lay

Answer 9

a. ontop of aryetnoids

Question 10

Epiglottic Cartildge connects where?

What type is it?

Answer 10

a. Connects to inside surface of thyroid

b. Elastic cartiledge—more flexible

Question 11

Tent-like fibrous sheets projecting medially; think the support where tent has surface is akin to vocal ligs

Answer 11

Lateral cricothyroid Ligaments

Question 12

Lateral cricothyroid Ligaments

Answer 12

medially connects to vocal ligament

Question 13

Thickended, superior, free edge of crocovocal membranes

Answer 13

Vocal ligaments

Question 14

Cricovocal membranes + vocal ligaments

Answer 14

Conus elasticus

Question 15

Quadrangular lies:

Answer 15

from epiglottis→ cartiledges;

Question 16

mucosa over vestibular ligaments

Answer 16

Vestibular folds

Question 17

mucosa covering vocal ligaments, cricovocal membranes + vocalis muscles

Answer 17

Vocal folds

Question 18

AIRWAY: Space between vocal folds in horizontal plane

Answer 18

Rima Glottis

Question 19

Space superior to vocal folds

Answer 19

Vestibule of Larynx

Question 20

btwn vestibular and vocal folds = space

Answer 20

Ventricle of Larnx

Question 21

Space inferior to vocal chords

Answer 21

Infraglottic cavity

Question 22

connects tongue and epiglottis

Answer 22

Glossoepiglottic fold

Question 23

Aditus laryngius

Answer 23

laryngeal inlet~ opening of larynx

Question 24

extend from artenoid cartilages to epiglottis, make up lateral wall of aditus laryngis

Answer 24

aryepiglottic folds

Question 25

Pear shaped space lateral to aryepglottic fold

Answer 25

Piriform recess

Question 26

tilts thyroid cart anteriorly, elongating and tightening

a. vocal ligements: pulled on to ↑ pitch of voice

Answer 26

Cricothyroids

Question 27

Cricothyroids innervated by:

Answer 27

External Larnyngeal (ONLY ONE!!)

Question 28

pulls arytenoid cartilededs together—thus affect width of rima glottidis or airway

Answer 28

Transverse Arythenoids

Question 29

Innervation of Transverse Arythenoids

Answer 29

Recurrent laryngeal

Question 30

Muscle that goes from one arytenoid cartiledge to other

Answer 30

Transverse Arytenoids

Question 31

like drawstring—shorten and contract to squeeze or push down on sides of atidus laryngus and pull on epiglottic fold

Answer 31

Oblique arytenoids

Question 32

Innervation of oblique arytenoids

Answer 32

recurrent layrngeal

Question 33

Pulls muscluar processes towards middle to ABduct vocal folds and open airway
a. cnxt and cause the arytenoid carts to swivel and twist so that the vocal processes end up farther apart and the rima glottidis opens up wider!

Answer 33

Posterior Cricoarytenoids

Question 34

Innervation of Posterior Cricoarytenoids

Answer 34

recurrently larnygeal

Question 35

Only muscle to open up the airway

Answer 35

Posterior Cricoarytenoids

Question 36

This muscle is from muscular processes of arytenoid cartiledges→ posterior part of cricoid

Answer 36

Posterior cricoarytenoids

Question 37

pulls arytenoid cartlage anteriorly to lower tension on vocal ligaments: ligaments become slack
Result: DECREASE pitch of voice

Answer 37

Thyroarytenoids

Question 38

Decreases pitch of voice

Answer 38

Thyroarytenoids

Question 39

Innervation of Thyroarytenoids

Answer 39

recurrent larnygeal

Question 40

Only muslce innervated by external larnygeal

Answer 40

Cricothyroids

Question 41

pulls muscluar processes anteriorly or forward to ADDUct vocal folds
the arythenoid cartiledges will go in opposite direction as what the posterior cricoarytenoids do by ABBducting or closing rima glottidis
Results = closes rima glottidis/aiway

Answer 41

Lateral Cricoarytenoids

Question 42

ADDucts vocal cords

Answer 42

Lateral Cricoarytenoids

Question 48

travels w/ superior laryngeal n piercing the thyroihyoid membrane

Answer 48
