Full Text. The hyoid bone is a horseshoe shaped bone found in the neck. Located anteriorly between the mandible and the thyroid cartilage, the hyoid bone protects the esophagus and also facilitates the wide range of muscle activity required for speaking and swallowing. It is visible upon extension of the neck.
The hyoid bone can be divided into three component parts: the body of the hyoid, the greater cornua, and the lesser cornua. The body of the hyoid is centrally located, while the cornua are on both sides.The lesser cornua are small conical projections oriented upwards.t is also at the base of the mandible, or lower jawbone. Unlike other bones within the skeleton, the hyoid does not feature any major points of articulation (joints) with other bones.
