What is the function of the larynx?
Respiratory modulation
Airway protection
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
