Across
  1. 8. regulates the functioning of the internal organs automatically without you having to consciously think about it
  2. 13. send information between sensory neurons and motor neurons
  3. 14. controls the automatic, vital bodily functions
  4. 16. filters sensory information and passes it to the relevant parts of the brain
  5. 17. responsible for detecting stimuli, carrying messages to and from the cns and effecting a response.
  6. 18. cord complex tract of nerve fibres stretching from the base of the brain to the lower back
  7. 20. the body's master information - processing and decision-making organ
  8. 25. carry sensory information from sense receptors towards the CNS
  9. 26. an unconscious, involuntary and automatically occurring response to a certain stimuli without any involvement of the brain
  10. 28. a change in the environment that is detected by a receptor
  11. 29. carry messages through an electrochemical process
  12. 30. controls sleeping, dreaming and waking
Down
  1. 1. when we need to prepare our body for vigorous activity or to deal with extreme emotions, stressful or threatening situation (fight,flight,freeze)
  2. 2. neuronal messages
  3. 3. transform environmental stimuli into electrical never impulses
  4. 4. control all voluntary movement of skeletal muscles
  5. 5. functions majority of the time when we do our everyday activity, helps maintain homeostasis
  6. 6. send information away from the CNS to muscles or glands
  7. 7. maintains homeostasis and releases hormones
  8. 9. the main information processing/ decision-mkaing division and is responsible for initiating response
  9. 10. filters incoming sensory information and affects what you pay attention to
  10. 11. in charge of balance and posture. It also coordinated muscle movement
  11. 12. fatty proteniod substance that covers the axon to insulate the electrical signal and allow the speed of transmission to increase
  12. 15. cell body, processes electrical signals and controls cell activity
  13. 19. organs that produce a response to a stimulus
  14. 21. responsible for the release of the electrical signal into the synapse
  15. 22. the receptor sites on the end of dendrites receive the neural impulse and send it to the soma for processing
  16. 23. a change in the organism resulting from the detection of a stimulus
  17. 24. responsible for everything we think,feel and do
  18. 27. neural impulses are transmitted along it by conducting electrical signals away from the body
