The tongue bone is called the hyoid bone.
The hyoid bone, located in the front of your neck, is unique because it doesn't directly articulate with any other bone in the body. Instead, it's suspended by muscles and ligaments. Its primary function is to support the tongue, giving it a stable base for movement, which is crucial for speaking, swallowing, and breathing. This "floating" characteristic is what makes it a distinctive feature of human anatomy. The hyoid bone is connected to structures such as the larynx, epiglottis, and the base of the tongue, contributing to the coordinated movements required for these vital functions.
