The hyoid bone does not articulate with any other bones.  It is held in place by ligaments to the styloid process of the temporal bone and the thyroid cartilage of the larynx.  It also has muscle attachments.  In spite of the fact that is not attached to the skull, it is considered part of the axial skeleton, specifically part of the skull.  It has a shape similar to the mandible, suggesting a common origin.  Functionally it is important because it is the origin of muscles that move the larynx during the act of swallowing.  It is the favorite bone of the seven dwarves and made famous in their song "Hyoid, hyoid, its off to work we goid".
