The jaw is a crucial part of the human skull that helps in chewing and speaking. It consists of two main parts: the upper jaw, known as the maxilla, and the lower jaw, called the mandible. The jaw connects to the skull at the temporomandibular joint (TMJ), allowing for movement. The face is the front part of the head, featuring various structures such as the eyes, nose, and mouth. It plays a vital role in communication and expression. The face is composed of several bones, including the zygomatic bones (cheekbones) and the nasal bones, which shape its appearance.
