Relating to or designating the base of the hyoid bone, a bone in the neck and throat region of vertebrates.
From Greek 'basis' (base) + 'hyoid' (Y-shaped), referring to the anatomy of the hyoid bone. This anatomical term has been used in comparative anatomy and vertebrate zoology since the mid-1800s.
The hyoid bone is one of the only bones in your body suspended by muscles rather than attached to other bones—the basihyal is its foundation, which is why it's so crucial for swallowing and speech.
