How can you stand, bend your arm, and jump while protecting organs inside you? Hidden inside you is more than a pile of hard parts: your skeleton is an internal framework, giving shape and support. When you stand, your spine supports you and protects the spinal cord. The skull protects your brain, while the rib cage helps protect your heart and lungs. But the skeleton is not just a rigid frame. It is a working system. Bones meet at joints, and muscles pull on them to create movement. That is how your arm bends, your legs push you into a jump, and you stay steady as you move. So, how can you stand, move, and protect organs at the same time? Your skeleton lets you do all three: bones support you, protect vital organs, and work with muscles to create movement.
