  The hyoid cartilage is formed of a series of skeletal elements: entoglossum (or paraglossals), basihyal (basihyoid), basibranchial (or urohyal), ceratobranchial, and epibranchial (Fig. 3.21), the most anterior of which (entoglossum and basihyal) constitute the tongue skeleton.

  In most mammals, the hyoid apparatus lies at or above the entrance to the larynx and consists of two basic parts: inferiorly, the unpaired basihyal and paired thyrohyal “horns” which connect the basihyal to the thyroid cartilage and superiorly, the paired suspensory stylohyoid chains which are made up of four cartilaginous or ossified links, the ceratohyal, epihyal, stylohyal, and tympanohyal, that connect the basihyal to the temporal bone (e.g., Howes 1896; Negus 1949).
