Across
  1. 4. brain region controlling the pituitary gland
  2. 6. a mechanism of response in which a stimulus creates reactions that reduce the stimulus
  3. 8. the part of a neuron (nerve cell) that receives the message and sends it to the cell body
  4. 9. neuron a nerve cell that carries a message from a receptor to the central nervous system
  5. 10. long projection of the neuron in which the electrical signal is passed down

  11. 23. Storage form of glucose in the muscles and liver
  12. 25. lobe A region of the cerebral cortex responsible for hearing and language.
  13. 26. nervous system Controls involuntary "flight or fight" response, part of PNS
  14. 28. the body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems
  15. 29. any information that the body receives that causes the body to respond
  16. 30. gland endocrine gland at the base of the brain
  17. 36. a nerve cell
  18. 37. lobe A region of the cerebrum that processes visual information
  19. 38. lobe associated with reasoning, planning, emotions, peronality and problem solving
  20. 39. a structure that detects a stimuli or change in the normal functioning of the body
  21. 40. stem the hindbrain, responsible for the survival functions of the body
Down
  1. 1. constant internal environment created by negative feedback mechanisms
  2. 2. a chemical messenger that moves across the synapse between the axon of one neuron and the dendrite of another neuron
  3. 3. an involuntary movement in response to a stimulus
  4. 5. hormone regulates water balance
  5. 7. a small gap between two neurons that must be crossed by neurotransmitters
  6. 8. Finger like projections of the neuron which receive stimuli from receptors
  7. 11. neuron a nerve cell that carries a message from the central nervous system to a muscle cell

  14. 23. An organ that produces and releases hormones into the bloodstream.
  15. 24. a nerve cell that links sensory and motor neurons; also known as a connector neuron
  16. 27. A hormone produced by the pancreas which reduces blood glucose concentration
  17. 31. the brain and spinal cord
  18. 32. lobe A region of the cerebrum whose functions include processing information about touch.
  19. 33. nervous system which contains all the neurons (nerve cells) that function outside the brain and spinal cord
  20. 34. the part of neuron which contains the nucleus
  21. 35. system the body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream
