This review focuses on the human skeletal system—the framework that gives our body shape, supports movement, and protects vital organs. It will cover the major bones, their functions, types of joints, and how the skeletal system works with muscles to allow motion. The review also includes key concepts such as bone growth, protection of internal organs, and the importance of maintaining healthy bones. This is designed to help students recall essential knowledge, check their understanding, and prepare for assessments related to the skeletal system.
