SKULL

A skull is the bony structure that forms the head in vertebrates, including humans, consisting of the cranium (which encases the brain) and the facial bones (supporting the face). In humans, it comprises 22 individual bones, most of which are fused by sutures, with the mandible (jawbone) being the only movable part. The skull protects the brain, supports sensory organs, and facilitates functions like eating and breathing. It’s a universal symbol of mortality, often featured in art, culture, and iconography (e.g., the “skull and crossbones” for danger or piracy).
