Elevate the larynx and pharynx

Pulls pharynx and larynx
upward
Assists in elevating the pharynx
and pulls on the torus tubarius
to pressure equalize the middle
ear
Tension and elongation of the
vocal folds
Abduts and laterally rotates the
cartilage pulling the vocal
ligaments away from the
midline, opening the rima
glottidis
Adduct and medially rotate the
cartilage pulling the vocal
ligaments towards the middline
