Functions of larynx

protects lower airway
produces sound
cough mechanism


Sup and Inf margin of larynx

sup - hyoid bone and epiglottis
inf - inferior edge of cricoid cartilage (around C6)


difference between thyroid and cricoid cartilage

cricoid - continuous (signet ring)
thyroid - no posterior cartilage

supra - from hyoid bone to vocal chords
glottis - true vocal chords
subglottis - below vocal folds to level of cricoid cartialge
