Which bone in the neck serves as a base for the tongue and does not articulate with any other bone?

• A. Hyoid bone
• B. Clavicle
• C. Mandible
• D. Sphenoid

Answer: (A)

The neck has a unique bone that acts as the anchor for the tongue and isn’t joined to any other bone. This bone sits in front of the larynx and is suspended by ligaments and muscles, not by joints. Its body and horns provide attachment points for many tongue, neck, and throat muscles, giving the tongue a solid base to move against during swallowing and speech. Because it doesn’t form a true joint with another bone, it remains independent in the skeleton—unlike the other options, which connect to surrounding bones (the clavicle to the sternum and scapula, the mandible to the temporal bone, and the sphenoid to multiple skull bones).
