Across
  1. 9. a neutral signal that promotes an electrical signal called action potential
  2. 10. the level of stimulation required to trigger a neural impulse
  3. 12. cells in the nervous system that support, nourish, and protect neurons
  4. 14. Fluid-filled brain areas
  5. 15. A visual display of brain activity that detects
  6. 17. The part if the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart).
  7. 19. Tissue destruction
  8. 21. The division of the autonomic nervous system that calms the body, conserving its energy.
  9. 25. a molecule that inhibits or blocks a neurotransmitter’s action
  10. 27. a molecule that increases a neurotransmitter’s action
  11. 31. Chemical messengers that are manufactured by the endocrine glands, travel through the bloodstream and affect other tissues.
  12. 32. in neural processing is a brief resting pause that occurs after a neuron has fired, subset action potentials cannot occur until that axon returns to its resting state
  13. 34. a neural impulse
  14. 36. A brain imaging technique that measures magnetic fields from the brain’s natural electrical activity.
  15. 37. A technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissues.
  16. 39. electrically charged atoms
  17. 43. the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body.
  18. 46. sympathetic and parasympathetic nervous system work together to keep us in a steady internal state called
  19. 47. In Front of the hypothalamus and is a limbic system reward center
  20. 50. neurotransmitter’s reabsorption by sending a neuron.
  21. 51. The belief that studying bumps on the skull could reveal a person's underlying brain size, character traits, and mental abilities
  22. 54. a neuron’s reaction of either firing (with a full-strength response) or not firing
  23. 55. is a nerve cell; the basic building block of the nervous system
  24. 56. Uses light to control the activity of individual neurons.
  25. 57. Helps coordinate movement and control sleep
  26. 58. is the loss of the inside/outside charge difference which causes the next axon channels to open
  27. 59. two lima-bean-sized neural clusters in the limbic system; linked to emotion such as aggression and fear
  28. 60. A type of MRI technology that maps long-distance brain fiber connections
  29. 61. The division of the autonomic nervous system that arouses the body, mobilizing its energy
Down
  1. 1. prevents action potential in a receiving neuron
  2. 2. the brain and spinal cord
  3. 3. Networks The brains neurons clusters into workgroups called
  4. 4. A nerve network that travels through the brainstem into the thalamus and plays an important role in controlling arousal
  5. 5. The endocrine system's most influential gland. Regulates growth and controls other endocrine glands.
  6. 6. neurotransmitters-messenger at every junction between motor neuron and skeletal muscles. When it's released muscles contract and when it is blocked muscles can’t contract and become paralyzed.
  7. 7. The junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron.
  8. 8. system Neural system (includes the amygdala, hypothalamus, and hippocampus) located below the cerebral hemispheres
  9. 11. a neuron's often bushy, branching extensions that receive and integrate messages, conducting impulses towards the cell body
  10. 13. the body’s speedy electrochemical communication network consisting of all the nerve cells of the peripheral and central nervous systems.
  11. 16. are chemical messengers that cross the synaptic gaps between neurons.
  12. 18. A fatty tissue layer segmentally encasing the axons of some neurons
  13. 20. Two-way information highway connecting the peripheral nervous system and the brain
  14. 22. A 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.
  15. 23. The body’s “slow” chemical communication system; a set of glands that secrete hormones into the bloodstream
  16. 24. A neural center located in the limbic system; helps process for storage explicit (conscious) memories of facts and events.
  17. 26. axon terminal of one neuron is separated from the receiving neuron by_____
  18. 28. The brain's sensory control center, located on top of the brainstem
  19. 29. A simple, automatic response to a sensory stimulus, such as the knee-Jerk response
  20. 30. A neural structure lying below the thalamus; it directs serval maintenance activities such as eating, drinking, body temperature
  21. 33. An amplified recording of the waves of electrical activity sweeping across the brain's surface.
  22. 35. The neuron extension that passes messages through its branches to other neurons or to muscles or glands
  23. 36. The base of the brainstem controls heartbeat and breathing
  24. 38. Can see brain activity as well as structure. Measures blood flow by comparing successive MRI scans.
  25. 40. neurons that carry incoming information from the body's tissues and sensory receptors to the brain and spinal cord
  26. 41. The division of the peripheral nervous system that controls the body’s skeletal muscles.
  27. 42. Brain activity supports mind wandering and daydreaming
  28. 44. neurons that carry outgoing information from the brain and spine to the muscles and glands.
  29. 45. The “little brain” at the rear of the brainstem
  30. 48. A pair of endocrine glands that sit just above the kidneys and secrete hormones (epinephrine and norepinephrine) that helps arouse the body in times of stress.
  31. 49. The oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull
  32. 52. “morphine within” natural opiates- like neurotransmitters linked to pain control and pleasure.
  33. 53. neurons within the brain and the spinal cord; they communicate internally and process information between the sensory inputs and motor outputs.
