Q

What connects the epiglottic cartilage to the arytenoid cartilage on each side?

A

Quadrangular Membrane

22
Q

What are the two parts to the Quadrangular Membrane?

A

Superior Margin: forms the aryepiglottic ligament within the aryepiglottic fold
Inferior margin: forms the vestubular ligament within the vestibular fold

23
Q

What does the vestubular folds do?

A

protective in function and initiates cough reflex (false vocal cords)

24
Q

What do the vocal folds do?

A

actively vibrate to produce sound (true vocal cords)

25
Q

What is the space between the vestibular folds

A

Rima Vestibuli

26
Q

What is the space between the vocal folds?

A

Rima Glottidis

27
Q

What includes the rima glottidis and the vocal folds?

A

Glottis

28
Q

What extends from the laryngeal inlet to the vestibular folds?

A

laryngeal vestibule

29
Q

What lies between the vestibular folds and vocal folds?

A

laryngeal ventricles

30
Q

What extends from the vocal folds to the inferior border of the cricoid cartilage?

A

infraglottic cavity

31
Q

What is a small diverticulum within the laryngeal ventricle?

A

laryngeal saccule

32
Q

In hoarseness due to excessive speaking or singing, lubricant from the laryngeal saccule is temporarily depleted and causes what?

A

laryngitis (inflammation of vocal cords)

33
Q

What are the elevators of the larynx?

A

thyrohyoid, stylohyoid, mylohyoid, digrastric, stylopharyngeus, palatopharyngeus

34
Q

What are the depressors of the larynx?

A

Omohyoid, sternohyoid, and sternothyroid

35
Q

What are intrinsic muscles of the larynx important for?

A

speech

36
Q

What is the only intrinsic muscle of the larynx you can see from the outside?

A

cricothyroid muscle

37
Q

What does the cricothyroid muscle do?

A

tilts thryoid cartilage downward or cricoid cartilage upward therby tensing the vocal cords (raises pitch of voice)

38
Q

What is the cricothyroid muscle innervated by?

A

External laryngeal nerve

39
Q

What does the posterior cricoarytenoid muscle do?

A

abducts the vocal cords

40
Q

What nerve innervates all of the intrinsic laryngeal muscles besides the cricothyroid muscle?

A

recurrent laryngeal nerve

41
Q

What is the neutral position of the vocal cords and what does it allow?

A

partially abducted, allows breathing when muscles are paralyzed and reduces risk of suffocation

42
Q

What is the whisper muscle and what does it do?

A

lateral cricoarytenoid muscle; adducts the vocal cords

43
Q

What are the couphing and sneezing muscles and what do they do?

A

transverse arytenoid and oblique arytenoid muscles; adducts vocal cords

44
Q

What muscle is active during swallowing in the larynx?

A

aryepiglottic muscle; closes the laryngeal inlet

45
Q

what muscle is a continuation of the oblique arytenoid and lies within the aryepiglottic fold?

A

aryepiglottic muscle

46
Q

what muscle deepens the voice and lowers its pitch?

A

thyroarytenoid muscle

47
Q

What muscle prevents monotone and “fine-tunes” the voice and what does it do?

A

vocalis muscle; adjusts tension on the vocal cords during phonation

48
Q

What determines voice dimorphism?

A

length of vocal cords, size of resonating chamber, and thickness of vocal cords (responds to androgens)

49
Q

What is the most important nerve of the larynx?

A

recurrent laryngeal nerve

50
Q

What is does the recurrent laryngeal nerve sense?

A

mucosa of the larynx below vocal fold

51
Q

What nerve is sensory to the mucosa of larynx above the vocal folds?

A

internal laryngeal nerve

52
Q

What are the blood vessels that supply the larynx?

A

superior laryngeal and inferior laryngeal arteries
