Structure
Sitting at the top of the larynx, this bone connects to the tongue and other major jaw muscles.
This muscle makes the vocal folds SHORTER and THICKER, resulting in lower notes. (must say full name)
What is the Thyroarytenoid (TA) muscle?
This is the action that pulls the vocal folds apart.
What is abduction?
This muscle makes up the main body of the vocal folds. (must say full name)
What is the Thyroarytenoid muscle?
This cartilage, sitting at the bottom of the larynx, is thicker in the back than it is the front.
What is the cricoid cartilage?
This muscle pulls the thyroids cartilage down to make the vocal folds THINNER and LONGER, resulting in higher notes. (Must say full name)
What is the cricothyroid (CT) muscle?
This is the empty space between the vocal folds.
This is how the laryngeal muscles are named.
By the cartilages they connect to on either end.
These two pyramid-shaped cartilages can slide together or apart.
What are the arytenoids?
This muscle goes between the two arytenoids, pulling them together. (must say full name)
What is the Interarytenoid (IA) muscle?
When THIS is complete, the vocal folds are fully closed together. When it is NOT complete, it may result in a breathy/airy sound.
What is glottal closure?
This is the area underneath the vocal folds
What is the subglottis?
This cartilage has a prominent notch in the front, which you can feel if you put your hand to your throat.
What is the thyroid cartilage?
This muscle performs vocal fold ADDUCTION on the bottom portion of the vocal folds. (Must use full name)
What is the Lateral Cricoarytenoid (LCA) muscle?
This is the slimy layer of the vocal folds that covers the main body of the fold.
What is the mucosal membrane?
Name all the bones/cartilages in the larynx.
What are the hyoid bone, the thyroid cartilage, the arytenoids, the epiglottis, and the cricoid cartilage?
This leaf-shaped cartilage flops over when swallowing to prevent food or drink from entering the larynx
What is the epiglottis?
This muscle performs vocal fold ABDUCTION. (Must use full name)
What is the Posterior Cricoarytenoid(PCA) muscle?
When air pushes through the vocal fold it causes it to do THIS, creating sound waves.
What is oscillation?
Name all of the laryngeal muscles. (Must use full names)
What are the TA, CT, LCA, PCA, and IA muscles?
