  • The hyoid bone is the one and only bone of the throat.
  • This horseshoe-shaped bone lies in between the chin and the thyroid ligament.
  • Interestingly, the hyoid bone does not connect to any other bones and is the only bone in the human body to do so.
  • Instead the bone connects solely to ligaments.

The primary function of the hyoid bone is to allow the movement of the tongue, pharynx, and larynx by connecting to muscles in the region.

Also the bone functions in the protection of these structures.

The hyoid bone is broken into three segments:

  • the body,
  • greater cornu,
  • and lesser cornu.

These segments can be seen in the image to the side.

On the superior side of the bone, the hyoid bone connects to

  • the middle pharyngeal constrictor muscle
  • hyoglossus muscle
  • digastric muscle
  • stylohyoid muscle
  • geniohyoid muscle
  • and mylohyoid muscle

On the anterior side of the bone, the hyoid bone connects to the

  • thyrohyoid muscle
  • omohyoid muscle
  • and sternohyoid muscle

That’s all their is to the Throat Bone.
