Summary Introduction
To write:
The location and functions of the three neural systems involved in the sleep-wake cycle.
Introduction:
Human body has a 24-hour internal clock. This clock regulates a number of processes such as sleep-wake cycles. During the rapid eye movement or REM sleep, the brainstem areas are usually inhibited. But during wake and slow-wake sleep (SWS), these become active. Incidentally, the ascending projections from the cholinergic neurons in the brainstem trigger the thalamus that in turn, increases the neurons firing in the cortex. This physiological modification from a deep sleep state to wakefulness is reversible and facilitated by the ARAS.

Describe the biological process of the sleep–wake cycle.
Compare and contrast the events and importance of slow-wave and REM sleep.
It is normal for sleep patterns to change with age. Select the description that best describes these normal changes:
a. Older adults spend less time in bed trying to sleep, increased time to fall asleep, decreased nighttime awakenings, and reduced quality and efficiency of sleep.
b. Older adults spend more time in bed trying to sleep, increased time to fall asleep, increased nighttime awakenings, and reduced quality and efficiency of sleep.
c. Older adults spend less time in bed trying to sleep, increased time to fall asleep, increased nighttime awakenings, and improved quality and efficiency of sleep.
d. Older adults spend more time in bed trying to sleep, increased time to fall asleep, decreased nighttime awakenings, and improved quality and efficiency of sleep.
