Q

What is the biological function of the vocal folds?

A

It is the gateway for breathing, it protects the airway/lungs, it expels foreign substances from the lungs by coughing, and it stabilizes the thoracic cavity for power in lifting/pushing (stabilized the core)

28
Q

Hyoid bone structure & function

A

it is a U shaped bone, it is “floating” because it is the only bone not connected to another bone, it is attached to the tongue, it connects the tongue to thyroid cartilage, 23 muscles attach to it, it is dynamic and moves a lot

29
Q

What type of joints are in the larynx?

A

Synovial joints (highly movable)

30
Q

What are the 2 joints in the larynx?

A

Cricothyroid joint & cricoarytenoid join

31
Q

Cricothyroid joint

A

A synovial joint that moves in a rocking and gliding rotation. It creates change in pitch

32
Q

Cricoarytenoid joint

A

A synovial join that moves in a rocking and gliding rotation. It adducts the vocal folds and changes their length

33
Q

Thyroid notch

A

The “adams apple” (a mans is usually bigger and a females is smaller)

34
Q

Laminae

A

The flat potion on the thyroid cartilage

35
Q

FEES

A

A swallowing study where you put a camera through the nose and watch the anatomy of the larynx as a person swallows different consistencies of food

36
Q

Stroboscopy

A

Contains and endoscope, a microphone, and a flashing strobe light that gives a clearer and deeper picture of the vocal folds while a person is producing different vibrations

37
Q

What are the vocal folds made out of?

A

Bands of mucous membranes, connective tissue, thyrovocalis muscle

38
Q

What are the main ligaments in the larynx?

A

Median thyroidhyoid ligament, lateral thyroidhyoid ligament, thyroid membrane, median cricothyroid ligament, cricothyroid ligament, cricotracheal ligament

39
Q

What is the function of the ligaments in the larynx?

A

They are fibrous connective tissue that connects and holds the bones are cartilages in the larynx together

40
Q

What ligaments connect the larynx to the hyoid bone?

A

Lateral thyrohyoid ligament, median thyrohyoid ligament, thyrohyoid membrane

41
Q

What ligaments connect the epiglottis to the larynx?

A

hyoepiglottic ligament, thyroepiglottic ligament

42
Q

What ligaments connect epiglottis to the tongue?

A

lateral glossoepiglottic ligaments, median glossoepiglottic ligaments

43
Q

What ligaments connect the thyroid to the cricoid?

A

Cricothyroid ligament, median cricothyroid ligament

44
Q

What ligaments connect the larynx to the trachea?

A

Cricotracheal ligament

45
Q

What are intrinsic muscles?

A

Muscles inside the vocal folds

46
Q

What are extrinsic muscles?

A

Muscles outside of the vocal folds that support it

What do the hyoid and laryngeal elevators do?

A

Want to move up the complex of the larynx

Q

Insertion

58
Q

What muscles attatches thyroid to hyoid?

A

thyrohyoid muscle

Q

Laryngeal cancer

A

Cancer cells form in the tissues of the larynx (tumor) and this can effect the muscles of the larynx

60
Q

A

One or more of the vocal folds do not open/close properly which can be caused by stroke, accidents, thyroid surgery complications

61
Q

Laryngectomy

A

Removal of a potion or the whole larynx (taking away someones voice)

62
Q

Tracheostomy

A

Surgical procedure that creates an opening in the trachea to insert a tube that allows you to breathe

63
Q

Vocal Nodules

A

64
Q

Vocal Polyps

A

Blisters on the vocal folds that are fluid filled (rough scratchy voice and cracking when speaking)

65
Q

Myasthennia Gravis

A

Disorder of muscles (can cause voice and swallowing issues)

66
Q

ALS

A

Disorder and break down of nerve impulses (swallowing difficulty, aspiration, speaking is more difficult)

67
Q

Reinke’s Edema

A

Fluid buildup that causes swelling (bc of abuse to the vocal folds- can lead to an abnormal voice)
