Exam #2

Hyoid bone

Attachment to the epiglottis and mucsles of jaw and tongue

Thyroid cartilage

anterior attachment of vocal folds posterior articulation with cricoid cartilage

cricoid cartilage

complete ring articulates with thyroid and arytenoids

arytenoid cartilages

Primary function of the larynx

stop you from inhaling food into your lungs (airway protection)

Secondary function

abdominal fixation (bracing to pick things up creating a more stable structure to pull against) creating more pressure in the body
