Primary function of ear is to capture sound energy.  Canal vibrates membrane, ossicles move and enhance the signal for premium level of energy.

Superior, middle and inferior constrictor muscles

Modality:  SVE for skeletal muscles.

Used to elevate and increase anterior posterior diameter for swallowing.

Muscles of soft palate pulls uvula to posterior wall eliminating posterior cavity to trachea.

Constrictors sequentially contract from superior to inferior.
