Functions of the Larynx
-Keeps food and drink out of the airway
-Acts as a sphincter during abdominal straining (ex. During defecation and heavy lifting)
What are the anatomical features of the larynx?
The nine c-rings, muscular walls, glottis, epiglottis, false vocal cords, and true vocal cords.
hyaline cartilage that form the framework of the larynx
aid in voice production and the swallowing reflex
the superior opening of the larynx
prevents food and drink from entering airway when swallowing
False Vocal Cords
aid in closing the glottis when swallowing
True Vocal Cords
produce sound when air passes between them
The shorter and thinner these membranes are, the faster air moves over them - produces high pitched sounds while the longer and thicker these membranes are, the slower air moves over them - produces low pitched sounds
