 Three sphincter muscles | aryepiglottic fod, ventricular fold, true vocal folds |
| major role of the larynx | protect airway, modulate airway dimensions |
| space between vocal folds | glottis |
| 4 parts of larynx | cartilage, mucousa, intrinsic, extrinsic |
| 9 cartilages | thyroid, cricoid, epiglottis, arytenoid, corniculate, cuneiform |
| thyroid | largest, forms 90-120 degree angle, prominence = adams apple, smaller degree |
| epiglottis | prevents food from entering larynx |
| arytenoid | controls length, tension, and position of vocal fold (abd and add) |
| cuneiform | loosely connects arytenoid cartilage to epiglottis |
| larynx moves up | swallowing |
| larynx depresses | yawning |
| 5 structures of vocal folds | epithelium (.05 mm), superficial, intermediate, deep, muscle |
| lamina propria | superficial, intermediate, deep |
| cover | epithelium, superficial, most flexible + vibratory |
| transition | intermediate, deep |
| mucousa | epithelium, superficial, intermediate |
| intrinsic muscles | interconnected in larynx, responsible for abduction, adduction, and tension |
| 5 intrinsic muscles | thyroarytenoid, cricothyroid, lateral cricoarytenoid, posterior cricoarytenoid, interarytenoid |
| shorten and thicken folds | thyroarytenoid, interarytenoid |
| elongate and thin folds | cricoarytenoid, lateral cricoarytenoid |
| abduction | posterior cricoarytenoid |
| adduction | lateral cricoarytenoid, interarytenoid |
