The flashcards below were created by user rere_girl4ever on FreezingBlue Flashcards. What would you like to do?


  1. What regulates the sleep cycle?
    Sleep cycle is regulated by the circadian rhythm, which is driven by SCN of hypothalamus.
  2. Circadian rhythm controls nocturnal release of which hormones and neurotransmitters?
    • ACTH, prolactin, melatonin, and norepinephrine:
    • Suprachiasmatic nucleus (SCN) -> ? norepinephrine release -> ? pineal gland -> ? melatonin.
  3. What causes Extraocular movements during REM sleep?
    due to activity of PPRF (paramedian pontine reticular formation/conjugate gaze center).
  4. Which drugs/ neurotransmitter are associated with decreased REM sleep?
    • Alcohol, benzodiazepines, and barbiturates are associated with decreased REM sleep and delta wave sleep
    • Norepinephrine also  decrease REM sleep.
  5. How do we treat bedwetting (sleep enuresis)?
    Oral desmopressin acetate (DDAVP), which mimics ADH
  6. How do we treat night terrors?
    Benzodiazepines
  7. How do we treat sleepwalking?
    Benzodiazepines
  8. Patient is awake (eyes open) Alert and has active mental concentration. What is ECG waveform is present?
    Beta (highest frequency, lowest amplitude)
  9. This frequency has the highest frequency, lowest amplitude.
    Beta
  10. Which sleep stage is the beta waveform present?
    • Awake (eyes open)- Beta (highest frequency, lowest amplitude)
    • REM- beta
  11. Patient is Awake (eyes closed). What is ECG waveform is present?
    Alpha
  12. During which sleep stage is the alpha waveform present?
    Awake (eyes closed)
  13. Describe the sleep stage of Stage N1 and which waveforms are present?
    • Light sleep
    • Theta
  14. During which sleep stage is the theta waveform present?
    • Stage 1
    • Light sleep
  15. Describe the sleep stage of Stage N2 nd which waveforms are present?
    • Deeper sleep; when bruxism (teeth grinding)occurs
    • Sleep spindles and K complexes
  16. Deeper sleep; when bruxism (teeth grinding)occurs is in which sleep stage. Waveforms?
    • Stage N2
    • Sleep spindles and K complexes
  17. This EEG waveform of this sleep stage is Sleep spindles and K complexes
    • Stage N2
    • Deeper sleep; when bruxism (teeth grinding)occurs
  18. Describe the sleep stage of Stage N3. Which waveforms are present?
    • Deepest non-REM sleep (slow-wave sleep); when sleepwalking, night terrors, and bedwetting occur
    • Delta (lowest frequency, highest amplitude)
  19. In this sleep stagesleepwalking, night terrors, and bedwetting occurs. Which waveforms are present?
    • Stage N3
    • Delta (lowest frequency, hights amplitude)
  20. This sleep wave has the lowest frequency, highest amplitude
    Delta
  21. Delta sleep waves are found in which sleep stage?
    • Stage N3
    • Deepest non-REM sleep (slow-wave sleep); when sleepwalking, night terrors, and bedwetting occur
    • Delta (lowest frequency, highest amplitude)
  22. What happens during REM sleep? What EEG waveform is present?
    • Loss of motor tone
    • Increased brain O2 use
    • Variable pulse and blood pressure
    • When dreaming and penile/clitoral tumescence occur
    • May serve a memory processing function
    • Beta
  23. Stages of the Sleep cycle
