UPDATED ACTUAL Questions and
CORRECT Answers
Biological rhythms - CORRECT ANSWER Biological rhythms are internal, natural cycles in living
things, like sleep-wake patterns (circadian), monthly cycles (infradian), and yearly cycles (circannual)
Circadian rhythm - CORRECT ANSWER Our bodies roughly synchronize with the 24-hour cycle
of day and night by an internal
biological clock
Pineal gland - CORRECT ANSWER Gland that produces melatonin
Melatonin - CORRECT ANSWER Sleep inducing hormone
REM sleep/paradoxical sleep - CORRECT ANSWER Rapid Eye Movement sleep; a recurring

muscles are relaxed (except for minor twitches) but other body systems are active.
Alpha waves - CORRECT ANSWER The relatively slow brain waves of a relaxed, awake state
Sleep spindles - CORRECT ANSWER Bursts of rapid, rhythmic brain-wave activity
EEG - CORRECT ANSWER a non-invasive brain-scanning technique that records electrical
activity via scalp electrodes, revealing brain wave patterns to study normal function (sleep, attention,
cognition) and diagnose disorders like epilepsy, sleep disorders, brain injury effects, or coma by showing
abnormal electrical spikes or slow waves
Delta Waves - CORRECT ANSWER The large, slow brainwaves associated
with deep sleep.
, Insomnia - CORRECT ANSWER Recurring problems in falling or staying asleep.
Narcolepsy - CORRECT ANSWER A sleep disorder characterized by uncontrollable
sleep attacks. The sufferer may lapse directly into

breathing
during sleep and repeated momentary awakenings.

of being terrified; unlike nightmares, night terrors occur during
NREM-3 sleep, within two or three hours of falling asleep,
and are seldom remembered.
REM Rebound - CORRECT ANSWER The tendency for REM sleep to increase following REM
sleep
deprivation (created by repeated awakenings during REM sleep).
Consciousness - CORRECT ANSWER our awareness of ourselves and our environment

drug, requiring the user to take larger and larger doses before experiencing the drug's effect.
