Describe why the Hyoid bone is so unique:
hyoid bone doesnt articulate with another bone, while all the other bones of the body articulate with other bones. the hyoid bone articulates with muscle, and is the attachment for the tounge, mandible, and larynx and holds the mucles in place. the hyoid is located in the neck
