false the superior longitudinal muscle elevates the tongue tip
T/F the posterior cricoarytenoid (PCA) is the only abductor of the intrinsic laryngeal muscles
True
T/F suprahyoid refers to structures running from the hyoid to structures above.

T/F the platysma depresses the mandible
True

Stylohyoid
What suspends the neck by the hyoid bone
the larynx
T/F the zygomatic major draws mouth up and medially.
true
T/F intrinsic muscles have both the origin and insertion on laryngeal cartilages.
true
T/F the PCA is an adductor
false the PCA is an abductor

true
The ___________ has two bellies and is an intrinsic laryngeal muscle.
digastric
