Support and Movement System
Learning Time: 5-15 hours
Content: The support and movement system consists of the skeletal and muscular systems and provides support, movement, and protection for internal organs. This topic covers bone structure (collagen, calcium), types of joints, muscle types (skeletal, smooth, cardiac), and movement mechanisms. The TYT focuses on bone and muscle structures, while the AYT focuses on muscle contraction and diseases. The current 2025 curriculum also includes sports injuries and biomechanical innovations (prosthetics). Understanding this topic is important for physical health and mobility.
