Across
  1. 3. two lima bean-sized neural clusters in the limbic system; linked to emotion
  2. 9. part of the peripheral nervous system that controls the glands the muscles of the internal organs (such as the heart). Its sympathetic division arouses; its parasympathetic division calms
  3. 14. nerve cell; the basic building block of the nervous system
  4. 16. technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. shows brain anatomy
  5. 17. pair of endocrine glands that sit just above the kidneys and secrete hormones that help arouse the body in times of distress
  6. 18. oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull
  7. 20. neuron's bushy and branching extensions that receive and integrate messages
  8. 24. chemical messengers that cross the synaptic gaps between neurons
  9. 28. neural center located in the limbic system; helps process for storage explicit 9concious0 memories of facts and events
  10. 29. body's speedy, electromechanical communication network, consisting of all the nerve cells of the peripheral and central nervous systems
  11. 33. part of the nervous system containing sensory and motor neurons that connect to central nervous system to the rest of the body
  12. 35. visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
  13. 36. cells in the nervous system that support nourish, and protect neurons
  14. 37. division of automatic nervous system that calms that body, conserving its energy
  15. 38. the division of the peripheral nervous system that controls the body's skeletal muscles
  16. 39. fatty tissue layer segmentally encasing the axons of some neurons
  17. 40. neurons that coming outgoing information from the brain and spinal cord to the muscles and glands
Down
  1. 1. part of nervous system containing the brain and spinal cord
  2. 2. natural opiate-like neurotransmitters linked to pain control and pleasure
  3. 4. brain imaging technique that measures magnetic fields from the brain's natural electrical activity
  4. 5. a molecule that inhibits or blocks a neurotransmitter's actions
  5. 6. a molecule that increases and neurotransmitter's action
  6. 7. nerve network that travels through the brainstem into the thalamus and plays an important role in controlling arousal
  7. 8. technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans.
  8. 10. the neuron extension that passes messages through its branches to other neurons or other muscles and glands
  9. 11. an amplified recording of the waves of electrical activity sweeping across the brain's surface; waves measured by electrodes placed on the scalp
  10. 12. neurons within the brain and spinal cord that communicate internally and process information between sensory inputs and motor inputs
  11. 13. tissue destruction
  12. 15. division of the automatic nervous system that arouses the body, mobilizing its energy
  13. 19. bundled axons that form neural cables connecting the CNS with muscles, glands, and sense organs
  14. 21. body's "slow" chemical communication system, a set of glands that secrete hormones into the bloodstream
  15. 22. series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice of the brain's structure
  16. 23. neural structure lying below the thalamus directs several maintenance activities (earing, drinking, body temperature), helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward
  17. 25. the base of the brainstem; controls heartbeat and breathing
  18. 26. brain's sensory control center, located on top of the brainstem; directs messages to the sensory receiving areas in the cortex and transmits replies in the cerebellum and medulla
  19. 27. body part of the neuron that contains nucleus; cell's life support system
  20. 30. neural system located below the cerebral hemispheres, associated with emotion and drives
  21. 31. "little brain" at the rear of the brainstem; functions include processing sensory input, coordinating output and balance, and enabling nonverbal learning and memory
  22. 32. brief resting period that occurs after a neuron has fired
  23. 34. neurons that carry incoming information from the body's tissues and sensory receptors to the brain and spinal cord
