W5 flashcards

Question 1

larynx

Answer 1

• connects the throat to the trachea
• allows our airways to be protected
• provides us with the ability to produce phonation

Question 2

larynx location

Answer 2

anterior of the neck at the C3-C6 vertebrae

Question 3

thyroid cartilage

Answer 3

facilitates the superior movement of the larynx during swallowing

Question 4

cricothyroid cartilage

Answer 4

complete ring of cartilage around the trachea

Question 5

upper larynx

Answer 5

Quadrangular membrane
Ventricular membrane

Question 6

lower larynx

Answer 6

conus elastics

Question 7

larynx region - Supraglottal region

Answer 7

ensure that food or liquids do not go in the wrong direction and into the lungs

Question 8

False vocal folds / ventricular folds

Answer 8

• Sit above the true vocal cords
• help prevent food from entering the trachea when swallowing

Question 9

true vocal folds

Answer 9

Formed by superficial border of the conus elastics that allow us to produce sound

Question 10

cricoarytenoid joint

Answer 10

• connects the cricoid cartilage and the arytenoid cartilage
• allows the vocal fold to open or close
• supports movement = rotate and glide
  pitch changes

Question 11

Intrinsic laryngeal muscles

Answer 11

types
- Adductors & abductors
- Tensors & relaxers

purpose
- open/ close vocal folds
- Tense / relax vocal folds

Question 12

Extrinsic laryngeal muscles

Answer 12

• Hyoid & laryngeal elevators & depressors
• works to elevate & depress larynx

Question 13

adduction - speech

Answer 13

• movement of the vocal folds toward the midline
• glottis folds CLOSED = for phonation to occur
  arytenoid cartilages

Question 14

Abduction - speech

Answer 14

• folds separated for voiceless sounds & breathing (rest position)
• opens glottis for whispering + breathing
• posterior cricoid cartilage & arytenoid cartilages

Question 15

length change - speech

Answer 15

• change in tension of vocal folds
• stretches & thins vocal folds which changes pitch

Question 16

glottis positions

Answer 16

• triangles joined = voiced
• triangles upside down = whispering
• triangles seperated/opened = breathing

Question 17

motor innervation

Answer 17

• Recurrent laryngeal nerve innervates all intrinsic laryngeal muscles ( except the cricothyroid)

Question 18

Sensory innervation

Answer 18

Mucosa above the vocal cords are innervated by branches of the superior laryngeal nerve

Question 19

larynx skeleton

Answer 19

= comprised of 6 cartilages

single cartilages
- epiglottis
- thyroid
- cricothyroid

paired cartilages
- aryntenoid
- corniculate
- cuniform

Question 20

larynx components

Answer 20

laryngeal inlet = opening
vestibule = entrance
ventricle = hollow cavity in organ
supraglottic cavity
glottis = vocal cords location
infraglottic cavity =

Question 21

larynx nerves

Answer 21

superior laryngeal nerve = sensory (vocal cords)

recurrent laryngeal nerve = motor
