"The hyoid bone is a midline "U or horseshoe-shaped" bone that serves as a structural anchor in the mid-neck. It is the only bone in the human body that does not directly articulate with another bone (other than sesamoids). It is a place of convergence of multiple small neck muscles that permit the pharyngeal phase of swallowing. The location of structures in the neck is often described in terms of relation to the hyoid (i.e. suprahyoid neck; infrahyoid neck)."
