What is the function of the hyoid bone?

• A. Articulates with the skull
• B. Supports the tongue and serves as attachment site for tongue and swallowing muscles
• C. Forms part of the rib cage
• D. Connects to the clavicle

Answer: (B)

The function being tested is the hyoid bone’s role as an anchor for the tongue and for muscles involved in swallowing. It sits in the front of the neck and doesn’t form joints with other bones, which lets it serve as a fixed attachment point. Muscles of the tongue, plus many muscles involved in swallowing, attach to the hyoid and pull on it to move the tongue, elevate the larynx, and help position structures during swallowing and speech. This makes the hyoid essential for coordinated tongue movement and swallowing. It doesn’t connect to the skull, form part of the rib cage, or connect to the clavicle, which is why those other options don’t fit.
