Which of the following is NOT a function of the hyoid bone?

The hyoid bone serves several important functions in the body, primarily related to the throat and the movement of the tongue, but it does not have a role in protecting the lungs. The hyoid bone is unique as it is not directly attached to other bones; instead, it is anchored by muscles and ligaments. One of its primary functions is aiding in swallowing, which is essential for the digestive process. It provides a foundation for the muscles involved in the act of swallowing.

Additionally, the hyoid supports the tongue, allowing for the necessary movements that facilitate speech and food manipulation. It also provides structural support for the larynx, which is essential for phonation. However, the hyoid bone does not contribute to the protection of the lungs. The lungs are primarily protected by the rib cage, which insulates them from external trauma and provides a bony structure that supports respiratory functions.
