Show Answers:

  1. Central Nervous System
    Spinal Cord and Brain. Processes information and directs actoins.
  2. Peripheral Nervous System
    Nerves not in bones. Send info to CNS.
  3. Somatic System
    Part of Peripheral Nervous System. Messages from senses.
  4. Autonomic System
    Part of Peripheral Nervous System. Controls Involuntary actions.
  5. Sympathetic System
    Part of Autonomic System. Fight or flight responses.
  6. Parasympathetic System
    Part of Autonomic System. Quiets body conserves energy.
  7. Soma
    Cell body of neuron 
  8. dendrites
    Receive the signal
  9. Axon
    Carries impulses from cell body
  10. Myelin Sheath
    insulates and protects neuron
  11. Synapse
    area between two neurons
  12. Axon Terminals
    Sends signal
  13. Resting potential/Action potential
    The value at which a neuron will or won't fire
  14. Spark
    When a neuron fires
  15. Refractory period
    The time a neuron waits until it can fire again
  16. All-or-None proposition
    a neuron either fires or it doesn't, no in between and  no strong or weak spark
  17. neurtransmitters
    the chemicals sent by neurons
  18. reuptake
    after a neuron sends a neurotransmitter  what isn't taken up is sucked back in by the axon terminal
  19. acetylcholine
    Enables muscle action, learning, and memory. Too little can cause Alzheimer's disease
  20. Dopamine
    Influences movement, learning, attention, and emotion. Too much: Schizophrenia Too little: Parkinson's disease
  21. GABA
    Inhibits central nervous system; regulates anxiety and movement. Too little: seizures, tremors, and insomnia.
  22. Glutamine
    Excites central nervous system; regulates learning and memory. Too much: Migraines and Seizures
  23. Norepinephrine
    Regulates mood changes and sleep. Too little: Depression
  24. Serotonin
    Regulates sleep, mood, appetite, pain, and emotion. Too little: depression
  25. Endorphines
    Inhibitory neural regulators involved in pain relief
  26. PET
    Positron emission topography. Scan can capture a picture of the brain as different parts are being used.
  27. MRI
    Magnetic resonance imaging. combines CAT and PET scans.
  28. CAT
    Computerized axial tomography. Scans were used to pinpoint injuries and other problems in brain deterioration.
  29. EEG
    electroencephalograph. Electrical activity of whole areas of the brain can be recorded.
  30. Phineas Gage
    Tamping iron entered Gage's head right below the left eye. Caused damage to frontal cortex, hurt thoughts and ideas.
  31. Hindbrain
    Rear base of skull. Involved in most basic processes of life
  32. medulla
    Breathing heart rate and blood pressure  
  33. Cerebellum
    Movement balance coordination and muscle tone
  34. Pons
    Lower brain w/higher brain. also does facial expressions
  35. Midbrain
    Small part above pons that integrates sensory information and relays it upward
  36. Reticular Activating System
    Alert brain to the rest of the brain to incoming signals
  37. Forebrain
    Brains central core
  38. Thalamus
    Relays info from all senses except smell--> too higher levels of brain
  39. Hypothalamus
    hunger thirst
  40. Limbic System
    Regulates emotions and motivatoins
  41. Amygdala
    rage and violence --> emotions
  42. Hippocampus
    formation of memory also smell
  43. Cerebral Cortex
    The different lobes of the brain
  44. Cerebrum
    Two hemispheres
  45. Frontal Lobe
    voluntary movement
  46. Parietal Lobe
    Skin senses
  47. Occipital Lobe
    Visual Cortex
  48. Temporal Lobe
  49. Corpus Callosum
    connects the two hemispheres
  50. Endocrine System
    Sends chemical messages called hormones/ another communication system
  51. Hormones
    Produced in the endocrine glands and are distributed by the blood and other body fluids.
  52. Pituitary Gland
    "Master Gland" located near the midbrain
  53. Thyroid Gland
    produces thyroxine
  54. Thyroxine
    stimulates certain chemical reactions important for all tissues of the body. Too little: feel lazy and lethargic
  55. Adrenal Gland
    Active when a person angry or frightened.
  56. Adrenaline
    endorphin also called Adrenaline
  57. Testosterone
