Which of the following describes the suprahyoid muscles?

Question

Quizplus · Accepted Answer

The suprahyoid muscles are a group of muscles that lie superior to the hyoid bone (which is a U-shaped bone in the neck) and help form the floor of the oral cavity. They include the digastric, mylohyoid, geniohyoid, and stylohyoid muscles.

Answer: C
 The suprahyoid muscles are involved in the movement of the larynx and hyoid bone. Specifically, they help to elevate the hyoid bone and larynx during swallowing, which helps to open the esophagus and allow food and liquids to pass through. However, if the mandible (jaw bone) is fixed (meaning it can't move), the suprahyoid muscles will instead depress the larynx and hyoid bone.

Answer: D
 The movement of the pharynx during swallowing is actually controlled by a different set of muscles called the pharyngeal constrictors. While the suprahyoid muscles do play a role in swallowing by elevating the hyoid bone and larynx, they do not specifically move the pharynx.
