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