Transcript

  • 1. THE SKELETAL SYSTEM
  • 2. 1. Skeleton - a framework of living bones that supports your body 2. Skeletal system – all the bones in your body make up the skeletal system 3. There are 206 bones in the human body
  • 3. • The skeleton has five major functions: 1) Gives shape and support to your body 2) Protect your internal organs 3) Help major muscles move 4) Form blood cells 5) Store calcium and phosphorous
  • 4. 4. The periosteum is the tight-fitting membrane that covers living bone. 5. Compact bone is the hard layer of bone directly under the periosteum.
  • 5. 6. Spongy bone is found at the ends of long bones and has many small, open spaces to make bones more lightweight. 7. Marrow is a substance found in the spaces in long bones. Marrow can be yellow (composed of fat cells) or red. *Red marrow produces red blood cells.
  • 6. 7. Cartilage is a smooth, thick layer of tissue that covers the ends of bones. - cartilage is flexible; it acts as a shock absorber and makes movement easier 8. A joint is any place where two bones come together 9. Ligaments are the tough bands of tissue that hold joints in place
  • 7. * Joints are generally classified as moveable or immoveable. 10. An immoveable joint allows little or no movement. The joints of the bones in the skull are immoveable.
  • 8. • There are 4 types of moveable joints: 1) Pivot joint – one bone rotates in the ring of another bone; the bones that allow you to turn your head are pivot joints
  • 9. 2) A ball and socket joint consists of a bone with a rounded end that fits into a cuplike cavity in another bone. (hips, shoulders…)
  • 10. 3) A hinge joint moves back and forth like a door hinge. (elbows, knees, fingers…)
  • 11. 4) A gliding joint is a joint in which one part of a bone slides over another. (wrists, ankles…)
  • 12. 11. Arthritis is the most common joint problem. - the word arthritis describes more than 100 different diseases that can damage joints - osteoarthritis is caused by a breakdown of cartilage - rheumatoid arthritis is a condition in which the body’s immune system destroys its own tissues
  • 13. Look alive, lazy bones!
