What is the anatomical term for the lower jawbone?

The lower jawbone is known anatomically as the mandible. It is the largest and strongest bone of the face and plays a crucial role in various functions, including chewing and speaking. The mandible connects to the skull at the temporomandibular joint (TMJ) and supports the lower teeth, making it essential for both dental health and facial structure.

In contrast, the maxilla refers to the upper jawbone that holds the upper teeth and forms part of the orbit of the eye. The zygomatic bone, also known as the cheekbone, contributes to the prominence of the cheeks and part of the eye socket. The temporal bone, located on the sides and base of the skull, houses structures of the ear and forms part of the jaw connection but is not involved in the lower jaw's function or structure. Therefore, the mandible is the correct choice as it specifically designates the anatomical term for the lower jawbone.
