Question

All of the functions listed below for the suprahyoid muscles are accurate, EXCEPT that they __________.

-act at the completion of swallowing to pull the hyoid bone and larynx inferiorly to their original position
-lie superior to the hyoid bone
-have an insertion on the hyoid bone
-help form the floor of the oral cavity and anchor the tongue
-elevate the hyoid and move the larynx superior during swallowing

Answer 1

"act at the completion of swallowing to pull the hyoid bone and larynx inferiorly to their original position" - False

The suprahyoid muscles do not depress the larynx (pull the larynx inferiorly), but rather, with the stylopharyngeus muscle, elevate it. The infrahyoid muscles depress the larynx.
All the other are accurate functions of the suprahyoid muscles. The suprahyoid muscles are: the stylohyoid muscle, the digastric muscle, the mylohyoid muscle, and the geniohyoid muscle.
