Which bone supports the tongue?

The hyoid bone is the structure that supports the tongue. It is a unique U-shaped bone located in the neck, situated between the chin and the thyroid cartilage. Unlike other bones in the body, the hyoid is not directly connected to any other bone, which allows it to be a mobile support structure for the tongue. This mobility is crucial for various functions, including swallowing, speaking, and controlling the movements of the tongue.

The hyoid provides attachment points for several muscles associated with the tongue and the floor of the mouth, facilitating the intricate movements required for these functions. Its position and structure make it essential for the overall functionality of the oral cavity and related actions.

In contrast, the mandible and maxilla are primary bones of the jaw that primarily function in chewing and speaking, while the palatine bones form part of the hard palate and are involved in the structure of the oral cavity but do not provide support to the tongue itself.
