Which of the following is not a pharyngeal muscle involved in swallowing?
A) pharyngeal constrictor muscle
B) palatopharyngeus
C) stylopharyngeus
D) omohyoid

Accepted Answer

The omohyoid muscle is not a pharyngeal muscle involved in swallowing. It is a strap muscle that originates from the scapula and inserts onto the hyoid bone, and its main function is to depress the hyoid bone. The pharyngeal muscles involved in swallowing include the pharyngeal constrictor muscle, palatopharyngeus, stylopharyngeus, and palatal muscles.
