Suprahyoid Muscles

The Suprahyoid Muscles (pronunciation: soo-pruh-hy-oid muh-suhlz) are a group of four muscles located superior to the Hyoid bone in the neck. These muscles include the Digastric, Stylohyoid, Mylohyoid, and Geniohyoid.

Etymology

The term "Suprahyoid" is derived from the Latin words "supra" meaning above, and "hyoides" referring to the shape of the Hyoid bone, which resembles the Greek letter upsilon.

Function

The primary function of the Suprahyoid Muscles is to elevate the Hyoid bone and the Larynx, which is essential during swallowing and speaking. They also aid in the opening of the mouth by depressing the Mandible.
