Transcript

  • 1. Human Locomotion
  • 2. Human Locomotion <ul><li>Involves the movement of </li></ul><ul><ul><li>Bones </li></ul></ul><ul><ul><li>Cartilage </li></ul></ul><ul><ul><li>Muscles </li></ul></ul><ul><ul><li>Tendons </li></ul></ul><ul><ul><li>Ligaments </li></ul></ul><ul><li>It allows humans to move from place to place </li></ul>
  • 3. Human Skeletal System <ul><li>It contains bones of many different shapes and sizes </li></ul><ul><ul><li>Purposes </li></ul></ul><ul><ul><ul><li>Support and protection of body structure </li></ul></ul></ul><ul><ul><ul><li>Anchors muscle action </li></ul></ul></ul><ul><ul><ul><li>Leverage fo body movement </li></ul></ul></ul><ul><ul><ul><li>Produces blood cells in the marrow </li></ul></ul></ul>
  • 4. Cartilage <ul><li>Connective tissues </li></ul><ul><ul><li>It is flexible and elastic </li></ul></ul><ul><ul><li>It give support </li></ul></ul><ul><ul><li>Flexibility of joints </li></ul></ul><ul><ul><li>Cushions effects in joints </li></ul></ul><ul><li>It makes up most of the body’s skeleton </li></ul><ul><li>By adulthood most of the cartilage is taken over by bones </li></ul><ul><ul><li>Found: </li></ul></ul><ul><ul><ul><li>End of ribs </li></ul></ul></ul><ul><ul><ul><li>Nose </li></ul></ul></ul><ul><ul><ul><li>Ears </li></ul></ul></ul><ul><ul><ul><li>bronchi </li></ul></ul></ul><ul><ul><ul><li>Trachea </li></ul></ul></ul>
  • 5. Human Muscular System <ul><li>There are three types of muscles in the human body </li></ul><ul><ul><li>Visceral </li></ul></ul><ul><ul><ul><li>Smooth in appearance </li></ul></ul></ul><ul><ul><ul><li>Involuntary in action </li></ul></ul></ul>
  • 6. Human Muscular System <ul><li>Cardiac muscles </li></ul><ul><ul><li>Involuntary in action </li></ul></ul><ul><ul><li>Striped in appearance </li></ul></ul><ul><li>Heart etc……………… </li></ul>
  • 7. Human Muscular System <ul><li>Skeletal Muscle </li></ul><ul><ul><li>Appearance </li></ul></ul><ul><ul><ul><li>Voluntary in action </li></ul></ul></ul><ul><ul><ul><li>Striped in appearance </li></ul></ul></ul><ul><ul><li>Controlled by the central nervous system </li></ul></ul><ul><ul><li>They are used to move bones in a coordinated manner </li></ul></ul><ul><ul><li>Muscles usually operate in pairs </li></ul></ul><ul><ul><ul><li>Which “pull” on the bones on either side </li></ul></ul></ul><ul><ul><ul><ul><li>INCLUDE </li></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Extenders- which extend the limbs </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Flexors – return the limbs (bend the joints) </li></ul></ul></ul></ul></ul>
  • 8. Tendons <ul><li>Made up of connective tissues </li></ul><ul><li>They are tough, inelastic </li></ul><ul><li>They connect the muscle to the bone </li></ul>
  • 9. Ligaments <ul><li>Made up of tough elastic connective tissue </li></ul><ul><li>Able to stretch slightly during joint movement </li></ul><ul><li>Connect bones at joints such as </li></ul><ul><ul><li>Elbows fingers knees </li></ul></ul>
  • 10. Problems that effect the Skeletal System <ul><li>Arthritis </li></ul><ul><li>Tendonitis </li></ul>
  • 11. Arthritis <ul><li>Inflammation of the joints causing swelling an horrible pain </li></ul><ul><ul><li>Cam occur at a young age </li></ul></ul><ul><ul><li>Usually occurs when old </li></ul></ul>
  • 12. Tendonitis <ul><li>Inflammation (swelling) of the tendons usually at the bone attachment </li></ul><ul><ul><li>Caused by physical stress and irritation to the spot </li></ul></ul><ul><ul><li>Common in athletes </li></ul></ul>
