Quiz #1 - Voice Disorders

What is the function of the larynx?

1. Respiratory modulation

2. Airway protection

3. Postural stability

What rocks back and forth and allows for the opening and closing of the vocal folds?

Cricoarytenoid joint

What is the standardized test/tool to access the voice?

CAPE-V (Consensus Auditory-Perceptual Evaluation of Voice)

What is the membrane that allows blood vessels and laryngeal nerves to enter into the larynx?

Thyrohyoid membrane

What is the vocal ligament made up of?

Intermediate lamina propria and deep lamina propria

What is the only intrinsic laryngeal muscle that abducts or opens the vocal folds?

Posterior Cricoarytenoid (PCA)

Know the cartilages of the larynx on a diagram

What cavity is below the glottis?

Subglottis

What are the three unpaired cartilages?

Epiglottis, thyroid, and cricoid

What are the three paired cartilages?

Arytenoid, corniculate, and cuneiform

Which cartilage “houses” the vocal folds?

Thyroid

Which cartilage has no role in voice?

Epiglottis

Which membrane houses the cuneiform cartilages?

Quadrangular membrane

Which membrane attaches the cricoid to the trachea?

Cricotracheal membrane

What do the muscles do?

Move the larynx when swallowing, breathing, and speaking

What do the cartilages do?

Help give the larynx its structure, like the walls of a house

What do the ligaments do?

Connect the cartilages and link the larynx to nearby structures like the hyoid above and the trachea below

What do membranes do?

Fibro-elastic material that help hold the cartilages in place

What do the extrinsic laryngeal muscles do?

Position the larynx in the neck and are split into groups, suprahyoid and infrahyoid

What do the intrinsic laryngeal muscles do?

Abduct (open), adduct (close), and tension

What is the function of the thyrohyoid muscle?

Decreases distance between thyroid and hyoid

True or False: The suprahyoid muscles move UP, while the subhyoid muscles move DOWN

True

Which muscle is divide into the thyromuscularis and thyrovocalis?

Thyroarytenoids

Which muscles are involved in pitch modulation?

Thyroarytenoids, cricothyroid, and lateral cricoarytenoids

What layers make up the “body” of the true vocal folds?

Deep lamina propria and thyroarytenoid
