Science Fact

Hyoid Bone

The hyoid bone, a U-shaped bone found below the tongue, is the only bone in the human body not directly touching another bone. It is connected to other bones only via ligaments.

Sometimes called the lingual bone, this piece of the skeleton serves to anchor and support the weight of the tongue, which is one of the factors that allow humans to vocalize a wide assortment of sounds and to articulate words.
