The skull is a bony structure that forms the head in humans and many animals. It protects the brain, which is one of the most vital organs in the body. The skull is made up of several bones that are fused together, providing a strong and stable framework for the face and head. In addition to protecting the brain, the skull also supports the facial features, such as the eyes, nose, and mouth. It plays a crucial role in our ability to chew food and speak. The study of the skull is important in fields like anatomy and paleontology, helping scientists understand both living creatures and ancient species.
