Essential Functions of the Skeletal System: Support, Protection, Movement, and More
The skeletal system performs five critical functions:
- Support: Provides structural framework for muscle attachment and body shape.
- Protection: Shields vital organs (skull protects brain; rib cage protects heart/lungs; vertebrae protect spinal cord).
- Movement: Bones act as levers; muscles pull on them to produce motion at joints.
- Mineral Storage: Reservoir for calcium and phosphorus, essential for bone and tooth health.
- Blood Cell Production: Bone marrow generates red cells, white cells, and platelets.
