MULTIPLE CHOICE
| a. | cortisol levels peak. |
| b. | cortisol levels increase. |
| c. | core body temperature increases. |
| d. | melatonin levels increase. |
ANS: D
Melatonin levels increase and core temperature and cortisol levels decrease with the onset of darkness. Cortisol levels peak at 6 A.M.

| a. | records brain waves and other variables. |
| b. | relays motor impulse to the hypothalamus. |
| c. | influences patterns of biological functioning. |
| d. | is affected by the light-dark cycle. |
ANS: B
The RAS receives sensory impulses from the spinal cord and relays motor impulses to the thalamus and all parts of the cerebral cortex. Polysomnography is the recording of brain waves and other physiologic variables, such as muscle activity and eye movements, during sleep. The circadian rhythms influence patterns of biological and behavioral functions, and the sleep-wake circadian rhythm is affected by the light-dark cycle.

| a. | “I know the circadian rhythm influences biological functions.” |
| b. | “I know the circadian rhythm exists only in humans.” |
| c. | “I know the sleep-wake circadian rhythm is impacted by the light-dark cycle.” |
| d. | “The most familiar circadian rhythm is the day-night 24-hour cycle.” |
ANS: B
Biological rhythms exist in plants, animals, and humans. In humans, these biorhythms, along with internal and external factors, affect sleep. The most familiar rhythm is the day-night, 24-hour circadian rhythm cycle. Circadian rhythms influence patterns of biological and behavioral functions. Some creatures are diurnal, or primarily active during the day, whereas others are nocturnal, with most of their activity during the night.

| a. | the recording of brain waves and other variables. |
| b. | the relay of motor impulse to the hypothalamus. |
| c. | the patterns of biological functioning. |
| d. | the recording of seizure activity in the brain. |
ANS: A
Polysomnography is the recording of brain waves and other physiologic variables, such as muscle activity and eye movements, during sleep. The reticular activating system (RAS) receives sensory impulses from the spinal cord and relays motor impulses to the thalamus. The circadian rhythms influence patterns of biological and behavioral functions. An electroencephalogram is used to record seizure activity in the brain.
