  1. What is your nervous system?

  2. Brain Olympics: YOUR MOTOR SYSTEMS

  3. Our brain controls our movements.

  4. Most of our behaviors involve moving. What are some things that we do that do not involving moving?

  5. How do we move? talks talk Brain Muscles

  6. Your brain tells your muscles to contract. When muscles contract your body moves.

  7. The part of the brain that makes us move is our motor cortex. Frontal Lobe

  8. The map of the motor cortex is known as the motor homunculus.

  9. Information from the motor cortex goes to the spinal cord and to the muscles.

  10. This pathway is known as the pyramidal system. Stimulation of the pyramidal system causes movements.

  11. The right side of our brain moves the left side of our body and vice versa.

  12. Our muscles talk to our brain… talk Brain Muscles …to tell us what they are doing.

  13. Our pyramidal system has extra help to make us move... …it is called the extrapyramidal system.

  14. Our extrapyramidal system controls… …if and how… we are going to move. Our extrapyramidal system controls… …how fast ….how far and …. the direction we move.

  15. Extrapyramidal system Basal Ganglia Cerebellum

  16. Our extrapyramidal system consists of the basal ganglia.

  17. Our basal ganglia helps to plan our movements. Touch your nose….. Finger or tongue?

  18. Our extrapyramidal system also consists of the cerebellum.

  19. Our cerebellum control how far, how fast, and the direction we move.

  20. Practice makes perfect... ...because of your extrapyramidal system.

  21. Our brain also needs information about the world to produce movments.

  22. Our brain and muscles talk very fast – and we can measure how fast. Reaction time talks talk Brain Muscles

  23. Reaction time measures how fast our motor pathway works. On your mark…. Get set….. Go!!!
