Across
  1. 5. neurons that carry outgoing information from the brain and spinal cord to the muscles and glands
  2. 6. a molecule that inhibits or blocks in our transmitters action
  3. 12. In neural processing a brief resting pause that occurs after a neuron has fired; subsequent action potentials cannot occur until the axon returns to its resting state
  4. 14. an Amplified recording of the waves of electrical activity sweeping across the brain surface these waves are measured by electrodes placed on the scalp
  5. 15. the body's slow chemical communication system; a set of glands that secrete hormones into the bloodstream
  6. 20. “morphine within” natural, opiate like neurotransmitters link to pain control and to pleasure
  7. 21. to Lima Bean sized neural clusters in the limbic system; link to emotion
  8. 22. neural center located in the limbic system; helps process for storage explicit memories of facts and events
  9. 24. A brain Imaging technique that measures magnetic fields from the brain's natural electrical activity
  10. 26. cells cells in the nervous system that support, nourish and protect neurons; they also play a role in learning, thinking, and memory
  11. 28. a nerve cell; the basic building block of the nervous system
  12. 31. The Junction between the axon tip of the sending neuron and a dendrite or cell body of the receiving neuron. The tiny Gap at this Junction is called the synaptic gap
  13. 33. chemical Messengers that are manufactured by the endocrine glands, travel through the bloodstream, and affect other tissues
  14. 34. the oldest part and Central core of the brain, beginning where the spinal cord swells as it enters the skull; the brainstem is responsible for Automatic Survival functions
  15. 36. the division of the peripheral nervous system that controls the body skeletal muscles also called the skeletal nervous system
  16. 37. chemical Messengers that cross the synaptic gaps between neurons when released by The sending neuron, neurotransmitters travel across the synapse and binds to receptors sites on the receiving neuron, thereby influencing whether that neuron would generate a neural impulse
  17. 38. series of X-ray photographs taken from different angles and combined by computer into a composite representation of a slice of the brain structure
  18. 42. division of the autonomic nervous system that calms the body, conserving its energy
  19. 44. when neurons reaction of either firing (with a full-strength response and) or not firing
Down
  1. 1. the body speedy, electrochemical communication Network, consisting of all the nerve cells of the peripheral and central nervous systems
  2. 2. internal structure lining below the thalamus; it directs several maintenance activities helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward
  3. 3. gland the endocrine system is most influential gland. Under the influence of the hypothalamus, the pituitary regulates Grove and controls all other endocrine glands
  4. 4. a visual display of brain activity but detects where a radioactive form of glucose goes while the brain performs a given task
  5. 6. the part of the peripheral nervous system that controls the glands and the muscles of the internal organs such as the heart. It's sympathetic division arouses; its parasympathetic division calms
  6. 7. a fatty tissue layer segmental encasing the axons of some neurons; enables vastly greater transmission speed as neural impulses hop from one node to the next
  7. 8. a simple, automatic response to a sensory stimulus, such as a knee-jerk response
  8. 9. the little brain at the rear of the brainstem; functions include processing sensory input, coordinating movement output and balance, and enabling nonverbal learning and memory
  9. 10. a nerve Network that travels through the brainstem into the thalamus and plays an important role in controlling arousal
  10. 11. the part of a neuron that contains the nucleus; the cell's life support center
  11. 13. the base of the brain stem; controls heartbeat and breathing
  12. 16. a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. MRI scans show brain anatomy.
  13. 17. a pair of endocrine glands that sit just above the kidneys and secrete hormones (epinephrine and norepinephrine and) that help arouse the body in times of stress
  14. 18. the division of the autonomic nervous system that arouses the body, mobilizing its energy
  15. 19. the sensory and motor neurons that connect the central nervous system the rest of the body
  16. 23. the brain sensory control center, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
  17. 25. a technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scan. Functional MRI scan how brain functions as well as structure
  18. 27. the brain in the spinal cord
  19. 29. a neurons often bushy, branching extensions that receive and integrate messages, conducting impulses toward the cell body
  20. 30. neurons that carry out incoming information from the body's tissues and sensory receptors to the brain and spinal cord
  21. 32. a molecule that increases a neurotransmitters action
  22. 35. neurons within the brain and spinal cord; they communicate internally and process information between the sensory inputs and motor outputs
  23. 39. neural system (including the amygdala, hypothalamus, and hippocampus)located below the cerebral hemispheres; associated with emotions and drives
  24. 40. the level of stimulation required to trigger a neural impulse
  25. 41. a neurotransmitters reabsorption by the sending neuron
  26. 43. are bundled axons that form neural cables connecting the central nervous system with muscles, glands, and sense organs
