32
Q

larynx

A

hollow, muscular organ that forms an air passage to the lungs and houses the vocal folds; below hyoid, above trachea; AKA voice box or Adam’s apple

33
Q

cricoid cartilage

A

only complete ring of cartilage in the larynx; most inferior part of larynx

34
Q

arytenoid cartilage

A

paired laryngeal cartilages that are small 3-sided pyramidal in shape; sit on posterior cricoid cartilage

35
Q

corniculate cartilage

A

paired small cartilages that sit atop arytenoid cartilages

36
Q

thyroid cartilage

A

largest of the laryngeal cartilages; not a complete ring; made of 2 laminae that come together to form the laryngeal prominence

37
Q

epiglottis

A

flexible, cartilaginous flap attached to entrance of the larynx; projects upward behind the tongue and hyoid bone

38
Q

cuneiform cartilage

A

small, paired, carrot-shaped cartilages at either side of the opening of the larynx; live inside of the aryepiglottic folds

39
Q

aryepiglottic folds

A

folds of mucosal tissue that course from arytenoids to the epiglottis; parallel to the lateral walls of the pharynx

40
Q

hyoid bone

A

only bone not connected to other bones; above the larynx, below the mandible
