This study unit will help you to:
- Identify the bony landmarks of the hyoid bone.
- List the muscles that attach to the hyoid bone.
- Name the cartilages, membranes, and ligaments that are adjacent to the hyoid bone.
The hyoid bone is a small U-shaped bone located in the anterior neck between the epiglottis and the thyroid cartilage. It does not articulate directly with other bones. Instead, it is connected to adjacent bones solely via muscles and ligaments. The hyoid bone serves as an attachment site for the muscles of the floor of the mouth, the tongue, the larynx, the epiglottis, and the pharynx.
Together with these muscles, the hyoid bone assists in movements, such as opening the jaw, articulating, swallowing, and coughing.
The following video will provide you with an overview of the hyoid bone and its adjacent structures.

The following gallery will provide you with an overview of the different muscles attaching to the hyoid bone:
|Parts||Central body, two lesser horns and two greater horns|
|Attaching muscles||Suprahyoid and infrahyoid muscles, certain pharyngeal muscles, and extrinsic tongue muscles|
|Function||Aids in opening the jaw, speaking, swallowing, and coughing|
