  1. Skeletal System

  2. Purpose • Support framework • Protects vital organs • Works with muscles to produce movement • Produces blood cells

  3. Facts • Your skeleton is made up of 206 bones • Bones start out as flexible cartilage but within a few weeks begin to develop into hard deposits of calcium through ossification. • It takes roughly 20 years for the ossification process to be completed • Bones are made up of types of material: compact and porous bone. • Bone marrow forms red and white blood cells

  4. Bone (same function as the system.) • structural material • Outer “shell” is hard • Inner portion is porous

  5. Bone marrow • Produces blood cells • soft tissue in center area of most bones

  6. Cartilage • Acts as a cushion where bones meet • Soft, connective tissue on the end of some bones • Vertebrae • Knee and hip joints • End of your nose

  7. Ligament • Tough fiber that connects bones together • Sprained ankles and knees are caused by stretched or torn ligaments

  8. Joint • Point where two bones meet • Ball and socket: hip and shoulder • Hinge: fingers, elbows, and knees • Pivot: Neck • Gliding: wrist

  9. Osteoporosis • A condition in which the bones become thin and brittle • Break more easily • Take longer to heal

  10. Why should teens care? • After age 30 you stop adding bone • If you don’t have enough calcium in your diet, your body takes it from your bones, leading to bone loss • You CANNOT make it up later; this is your ONE chance • Build up your savings account now!

  11. Problems: • Fractures: a break in a bone • Dislocation: a bone being pushed out of joint • Sprain: stretching or twisting of a ligament • Osteoarthritis: a breakdown of cartilage caused by wear and tear • Scoliosis: a sideways curvature of the spine

  12. Diet and Osteoporosis • Calcium and phosphorous form the hard substance in bone • Foods high in calcium: milk and milk products, and dark green leafy vegetables • Vitamin D helps your body absorb calcium • Our bodies make vitamin from sun exposure • Most milk and milk products in the US are fortified with Vitamin D • Teens need 4 servings of calcium rich foods every day

  13. Physical activity and Osteoporosis • Weight-bearing physical activity 2 to 3 times per week • sends signals to your body to make the bones stronger • Physical activity 60 minutes every day • Stronger muscles protect joints

  14. Seven ways to keep your skeletal system healthy • Eat food and beverages rich in calcium, phosphorus, and vitamin D • Wear protective equipment when playing sports • Exercise regularly to strengthen joints and ligaments • Sit, stand, and walk with correct posture

  15. 5. Warm up before participating in physical activity 6. Get screened for scoliosis 7. Wear properly fitting, well-cushioned shoes
