cuneiform cartilage

thyroid cartilage

largest

made up of two laminae that join at the midline anteriorly

superior and inferior horns

incomplete posteriorly

thyrohyoid membrane

thryroid cartilage articulate with the hyoid bone superiorly via the _____ _____

cricothyroid joints

thyroid cartilage articulate with the cricoid cartilage inferiorly via the ______ ______

cricothyroid joints

Action at this joint: thyroid cartilage tips anteriorly to increase tension on vocal folds

cricoid cartilage

forms a complete ring around the airway

inferior to thyroid cartilage

epiglottic cartilage

articulates with and is encompassed by teh thyroid cartilage

shaped like a leaf with a stem

mobile during degultition (swallowing)

arytenoid cartilages

sit directly atop the cricoid cartilage posteriorly

vocal process (anterior) and muscular process (posterolateral)

attachment site for vocal ligaments

pivot and glide to position vocal ligaments

corniculate cartilages

act to extend attachment surface for arytenoid cartilages

sit atop arytenoid cartilages

cuneiform cartilages

embedded within the ary-epiglottic folds that span the distance between the arytenoid and epiglottic cartilages

provide structural support for the walls of the laryngeal inlet

hyaline cartilage
