Laryngeal Muscles Quiz - A&P

intrinsic muscle attachments are (a)   the larynx

Which is NOT an intrinsic laryngeal muscle function?

• Closing the glottis

• Modifying pitch

• Transport food to stomach

• Opening the glottis

Adductors (a)   the glottis.

I am found in the supraglottic space

• arytenoids

• epiglottis

• ventricles

• all of these

I am attached to the posterior lamina of the cricoid and the muscular process of the arytenoid. I am an abductor.

• Thyroarytenoid

• Posterior Cricoarytenoid

• Lateral Cricoarytenoid

• Cricothyroid

I have two bellies: the transverse and the oblique.

• Thyroarytenoid

• Lateral Cricoarytenoid

• Interarytenoid

• Posterior Cricoarytenoid

I have two functions: pitch modification and adduction.

• thyroarytenoid

• lateral cricoarytenoid

• interarytenoid

• posterior cricoarytenoid

Abductors (a)   the glottis.

When I contract, vocal fold mass increases, resulting in slower vibration and lower pitch.

• posterior cricoarytenoid

• thyroarytenoid

• lateral cricoarytenoid

• interarytenoid

When the (a)   muscle contracts, the thyroid cartilage is pulled anteriorly and inferiorly, which stretches the vocal folds.
