What is the name of the lower jawbone?

The lower jawbone is referred to as the mandible. It is the largest and strongest bone in the face, playing a crucial role in functions such as chewing, speaking, and maintaining the structure of the lower face. The mandible holds the lower teeth in place and connects to the skull at the temporomandibular joint (TMJ), allowing for movement necessary for biting and chewing.

In contrast, the maxilla is the upper jawbone, which carries the upper teeth and forms part of the orbits of the eyes. The zygomatic bone, also known as the cheekbone, contributes to the prominence of the cheeks and forms part of the eye socket, while the temporal bone is located on the sides of the skull and plays a role in housing structures of the ear and forming part of the cranial cavity. Understanding these definitions is essential for anyone studying anatomy and esthetics, as they relate to facial structure and functions critical to beauty and skincare treatments.
