Flat bones are a specific type of bone in the human body characterized by their thin, flattened, and usually curved structure. They are designed to offer protection to vital organs and provide large surface areas for muscle attachment. These bones aren't hollow like long bones; instead, they consist of two layers of compact bone enclosing a layer of spongy bone, giving them their sturdy yet lightweight nature. Flat bones, such as the sternum, ribs, and certain bones in the skull (like the parietal bones), play crucial roles in safeguarding organs and facilitating bodily movements.
