1. Understanding the Musculoskeletal System

2. What is the Musculoskeletal System? A complex system that gives our body support and movement Made up of bones, muscles, cartilage, tendons, ligaments, and joints Works together to provide form, stability, and mobility What other body systems do you think interact with the musculoskeletal system?

3. The Skeletal System's Role Protects internal organs Supports body weight Stores important minerals (calcium and phosphorus) Produces blood cells through hematopoiesis Can you name 3 organs that are protected by bones?

4. The Muscular System's Functions Keeps bones properly positioned Contracts to pull on bones Enables various movements: Standing, walking, running Grasping and manipulating objects

5. How Joints Connect Everything Joints are connection points between bones Allow for controlled movement Contain protective cartilage Connected by tendons and ligaments What would happen if we didn't have joints?

6. Understanding Tendons vs Ligaments Tendons: Connect muscles to bones Ligaments: Connect bones to other bones Both are made of strong connective tissue Both help stabilize joints

7. The Movement Process Muscles contract (bunch up) Tendons pull on bones Joints allow controlled motion Cartilage prevents bone friction How is this like a puppet's movement system?

8. Protection Features Bones form protective cages (like the ribcage) Muscles provide padding Cartilage acts as a shock absorber Joints enable flexible protection

9. Mineral Storage and Management Bones store 99% of body's calcium Also store phosphorus Act as mineral bank for body Release minerals when needed Why do you think mineral storage is important?

10. Blood Cell Production Bones contain bone marrow Produces red blood cells Creates white blood cells Makes platelets How does this connect to your immune system?

11. Common Musculoskeletal Problems Malnutrition effects Arthritis Joint damage Mobility issues What lifestyle choices might help prevent these issues?

12. Understanding Arthritis Inflammation of joints Can limit movement May cause severe pain Can progress over time

13. Modern Medical Solutions
