The sternohyoid muscle, Omohyoid muscle, and Thyroid muscle are three muscles that are responsible for the depression of the hyoid bone.
The action of the omohyoid is to depress the hyoid. Its name derives from the Greek "omos" meaning shoulder, giving one of its attachments, and "hyoid", giving the other attachment - the hyoid bone. The function of the hyoid seems to be in voice variations. All mammals have them and there are arguments if primitive hominids used them as we do.
B. Omohyoid. The omohyoid muscle is not directly involved in the process of chewing or manipulating food in the mouth. It acts to depress and stabilize the hyoid bone in the neck.
