Across
  1. 2. a nerve cell; the basic building block of the nervous system
  2. 3. chemicals messengers that are manufactured by the endocrine glands, travel through the bloodstream and affect other tissues
  3. 5. sheath a fatty tisue layer that covers the axon of some neurons
  4. 6. the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; repsonsible for automatic survival functions
  5. 9. ¨morphins within¨ natural opiate-like neurotransmitters linked to pain control and to pleasure
  6. 11. in neural proccessing, a brief resting pause that occurs after a neuron has fired
  7. 13. a neurons ofen bushy, branching extensions that receive and intergrate messages, conducting impulses toward the cell body
  8. 16. a simple, automatic response to a sensory stimulus such as the knee jerk response
  9. 17. a molecule that increases a neurotransmitters action
  10. 18. a neural center located in the limbic system; helps process for storage explicit memories of facts and events
  11. 20. cells in the nervous system that support, nourish and protect neurons; they also play a role in learning, memory and thinking
  12. 21. a technique for revealing bloodflow and, therefore, brain activity by comparing successive MRI scans; shows brain function as well as structure
  13. 23. network
  14. 25. the endocrine systems most influential gland; regulates growth and controls other endocrine glands
  15. 26. the nueron extension that passes the messages through its branches to other neurons or to muscles or glands
  16. 28. the ¨little brain¨ at the rear of the brainstem
  17. 29. a pair of endocrine glands that sit just above the kidneys and secrete hormones that help arouse the body in times of stress
  18. 30. a brain imaging technique that measures magnetic fields from the brains natural electrical activity
  19. 31. the part of the peripheral nervous system that controls the glanda and muscles of the internal organs
  20. 32. the part of a neuron that contains the nucelus; the cells life support system
  21. 34. the brains sensory control center located on top of the brainstem
  22. 35. the divsion of the peripheral nervous system that controls the bodys skeletal muscles
  23. 37. neurons neurons that carry outgoing info from the brain and spinal cord to the muscles and glands
  24. 38. a neural impulse; a brief electrical charge that travels down a axon
  25. 40. a nerve network that travels through the brainstem into the thalamus and plays an important role in controlling arousal
  26. 43. the divsion of the autonomic nervous system that arouses the body, mobilizing its energy
  27. 44. chemical messangers that cross the synaptic gaps between neurons.
  28. 45. the brain and spinal cord
Down
  1. 1. the bodys ¨slow¨ chemical communication system; a set of glands that secrete hormones into the bloodstream
  2. 4. bundled axons that form neural cables connecting the central nervous system with the muscles, glands and other sense organs
  3. 7. the bodys speedy, electrochemical
  4. 8. the base of the brainstem; controls heartbeat and breathing
  5. 10. the division of the autonomic nervous system that calms the body, conserving energy
  6. 12. neurons within the brain and spinal cord and brain; they communicate internally and process info between the sensory inputs and motor outputs
  7. 14. the level of stimulation required to trigger a neural impulse
  8. 15. neurons neurons that carry incoming info from the bodys tissues and sensory receptors to the brain and spinal cord
  9. 17. a neurons reaction of either firing with full strength or not firing
  10. 19. the sensory and motor neurons that connect the central nervous system to the rest of the body
  11. 22. a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
  12. 24. an amplified recording of the waves of electrical activity sweeping across the brains surface
  13. 27. the junction between the axon tip of the sending neuoron and the dendrite or cell body of the receiving neuron.
  14. 33. a series of x-ray photos taken from different angles and combined by computer into a composite representation of a slice of the brains structure
  15. 36. a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue; shows brain anotomy
  16. 39. a molecule that inhibts or blocks a neurotransmitters action
  17. 41. a neurotransmitters reabsoprtion by sending the neuron.
  18. 42. tissue destruction
