Study Notes
- The skeleton is the collection of bones that supports the body
- The skeleton has three major functions
Protection
- The skeleton protects vital organs
Shape
- The skeleton provides the body's shape
- Without a skeleton, the body would be a shapeless mass
Movement
- The skeleton enables movement
- Muscles attach to bones
- When muscles move, they move the bones, resulting in movement
