  1. Group 8 • Duncan, C.; Morando, A.; Robinson, R. • Chapter 15: Integumentary, Skeletal, and Muscular Systems • Lesson 2: The Skeletal System • 8th Grade • 13-14 Year Olds

  2. The Skeletal System

  3. What Does My Skeletal System Do? • Structure • Stability • Movement • Protection

  4. Structure-How We’re Put Together • Axial (skull, spine, ribs, sternum, breastbone) • Appendicular (shoulders, arms, legs, hands, hips, feet)

  5. What’s Inside Our Bones? • Spongy Bone • Marrow Cavity • Compact Bone • Cartilage

  6. Different Types of Bones • Long • Short • Flat • Irregular

  7. Cartilage • A type of connective tissue • Lines joints to cushion the bone and allow the joint to move easily without pain • Helps form flexible portions of the nose and ear

  8. Joints • Ball-and-Socket • Pivot • Ellipsoidal • Hinge

  9. Practice • What kind of joint is your knee? • What about your hip? • Elbow? • Shoulder?

  10. Ligaments and Tendons • Ligaments connect bone to bone • Tendons connect muscle to bone

  11. Eating Your Way to Strong Bones • Diet • Milk is rich in calcium and high-quality protein. Nearly all U.S. milk has vitamins D and A added and it has magnesium and zinc. • All of these vitamins and minerals help build strong bones.

  12. How do Healthy Bones Sound to You?

  13. Why Drink Milk? • Could this happen to you?

  14. Work Your Bones Weight Lifting • Exercise • Weight bearing exercise makes your bones strong and healthy • it stimulates bone formation and strengthens the muscles connected to the bones Baseball Aerobics Basketball

  15. Walk Your Way to Healthy Bones

  16. Problems of the Skeletal System • Fractures • Hairline • Transverse • Comminuted

  17. What? A disease causing the bones to become very porous This makes bones prone to fractures and slow to heal Who? Most common in women following menopause More common in females Osteoporosis

  18. Osteoporosis

  19. What? An abnormal lateral curvature of the spine Who? Scoliosis can affect anyone Why? Birth defect Nerve or muscle problems deterioration of the bony material (discs) that separate the vertebrae Scoliosis

  20. Joint Injuries • Dislocation • Torn cartilage • Bunion • Bursitis • Arthritis

  21. Repetitive Motion Injury • What? • an injury or illness resulting from bodily motion which imposes stress or strain upon some part of the body due to the repetitive nature of a task • Examples • Carpal tunnel syndrome • Gamer’s Thumb

  22. THE END!
