The hyoid muscles are found in the anterior part of the neck. As their name suggests, they attach to the hyoid bone.
The hyoid muscles are divided into the supra- and infrahyoid groups, and they are named after the structures they attach to.
Suprahyoid muscles
The suprahyoid muscles attach to the hyoid bone and a structure above it. These muscles elevate the hyoid bone and the larynx, as well as form the floor of the mouth (oral diaphragm, formed by the mylohyoid muscle):
- Stylohyoid
- Mylohyoid
- Geniohyoid
- Digastric
Stylohyoid
The stylohyoid is a slender muscle attaching the styloid process to the hyoid bone.
