Hyoid is the bone of

Skull is the possible answer.

The hyoid bone is a unique bone located in the neck. It is the only bone in the human body that does not articulate with any other bones. Instead, it is suspended in the neck by a network of muscles and ligaments.

The hyoid bone serves as an attachment point for various muscles of the tongue, throat, and larynx, and it plays a crucial role in swallowing, speaking, and supporting the structure of the throat. While it is not entirely a part of the skull, it is anatomically close to the skull and located just below the mandible (lower jawbone).
