Transcript of "The nervous system"

  1. 1. Key Questions  What are the different Nervous Systems?  What are the functions different Nervous Systems?  Can the Nervous System be trained?  How are messages sent from the Brain and transferred by the neurons?
  2. 2. A system that controls all of the activities of the body. The nervous system is made of: The brain The spinal cord The nerves The senses
  3. 3. The nervous system also allows you to react to a stimulus. A stimulus is a change in the environment. Example: A tennis Serve Or… being tackled in football
  4. 4. Your reactions are automatic. Automatic means that you do not have to think about your reactions. Example: Reflex catch in the slips
  5. 5. An organ that controls your emotions, your thoughts, and every movement you make.
  6. 6. The Nervous Systems Central, Peripheral and Autonomic
  7. 7. The Central Nervous System is made of the brain and the spinal cord. The Central Nervous System controls everything in the body.
  8. 8. The Outer Nervous System is made of the nerves and the sense organs. Nerves Sense organs
  9. 9. * The Central Nervous System controls all of the body’s activities. * The Central Nervous System is made of two main organs. 1. The brain 2. The spinal cord
  10. 10. * The spinal cord sends messages to the brain. * The spinal cord is the part of the nervous system that connects the brain to the rest of the nervous system.
  11. 11. * The brain controls everything in the body. * The brain is made of more than 10 billion nerves! * The brain is divided into three parts and is protected by the skull.
  12. 12. * The Brain has three main parts… 1. The Cerebrum 2. The Cerebellum 3. The Brain Stem
  13. 13. * The Cerebrum is the largest part of the brain. 1. The cerebrum controls your thinking. 2. The cerebrum controls your memory. 3. The cerebrum controls your speaking. 4. The cerebrum controls your movement and identifies the information gathered by your sense organs.
  14. 14. * The cerebellum is below and to the back of the cerebrum. 1. The cerebellum controls you balance. 2. The cerebellum controls your posture.
  15. 15. * The Brain Stem connects the brain to the spinal cord. * The nerves in the brain stem control your heartbeat, breathing, and blood pressure.
  16. 16. * The vertebrae are the many bones that protect the nerves in the spinal cord.
  17. 17. Key Parts of the CNS
  18. 18. * The nervous system carries messages between the central nervous system and the rest of the body. * The Outer Nervous System’s job is to connect the Central Nervous System to the rest of the body.
  19. 19. * The nervous system is made of the nerves and the sense organs. Eye Ear Skin Nerves Tongue
  20. 20. Messages carried throughout the body by nerves.
  21. 21. Transmitting a nerve impulse is an almost instantaneous process A message is transferred down the neuron to the axon terminals Once it reaches the axon terminals chemicals are released into the ‘synapse’ These chemicals are then transferred to receptor sites on the dendrites The nervous impulse is continued on to the next neuron
  22. 22. * The Autonomic nervous system controls the body’s activities that you don’t think about. * The Autonomic nervous system controls activities in your small intestine, your breathing, and your heartbeat. controls
