Across
  1. 3. automatic, inborn response to a sensory stimulus
  2. 6. callosum Neural fibers carry messages between the two brain hemispheres
  3. 8. A computerized radiographic technique used to measure metabolic activity in brain
  4. 11. potential A neural impulse is a brief electrical charge that travels down an axon.
  5. 12. nervous system The peripheral nervous system controls the body's skeletal muscles
  6. 14. Scan X-ray photographs combined to create a composite image of the body.
  7. 15. opiatelike neurotransmitters linked to pain control and to pleasure
  8. 17. areas The cerebral cortex is involved in higher mental functions such as learning, remembering, thinking, and speaking
  9. 18. Endocrine glands produce chemical messengers that affect other tissues.-
  10. 21. system The hippocampus, amygdala, and hypothalamus are neural structures associated with emotions and drives, such as fear and aggression.
  11. 25. cortex The brain is the body's control and information-processing center
  12. 26. formation The brainstem is responsible for controlling arousal-
  13. 27. transport information from the central nervous system to muscles and glands.-motor
  14. 29. tiny gaps between dendrites and axons of different neurons-
  15. 30. lobes Visual areas of the back of the head receive visual information from the opposite visual field.
Down
  1. 1. lobes The cerebral cortex is responsible for speaking, muscle movements, and making decisions.
  2. 2. area The temporal lobe is responsible for language comprehension and expression
  3. 4. process by which organisms maintain a relatively stable internal environment
  4. 5. Neural clusters in the limbic system are linked to emotions
  5. 7. the level of stimulation required to trigger a neural impulse-
  6. 9. The brain's sensory switchboard directs messages to the cortex and transmits replies to the cerebellum
  7. 10. located in the limbic system that helps process explicit memories for storage
  8. 13. nervous system What system is the brain and spinal cord in
  9. 16. is the oldest part of the brain, responsible for survival function.
  10. 19. the basic building block of the nervous system
  11. 20. Neural "cables" connect the central nervous system to muscles, glands, and sense organs.
  12. 22. area of the brain responsible for all voluntary activities of the body
  13. 23. base of the brainstem; controls heartbeat and breathing
  14. 24. psychology a branch of psychology concerned with the links between biology and behavior
  15. 28. brain The two hemispheres of the brain are isolated by cutting the connecting fibers.
