The Hyoid Bone

Information

The hyoid bone in the neck is the only bone in the body that does not articulate directly with at least one other bone. It is U-shaped and is held in place by, and helps anchor, muscles that connect to the floor of the mouth and the tongue. It helps provide greater movement of the tongue and larynx, and so is crucial to human speech.

In about 50% of strangulations, the hyoid bone is fractured.
