If you could help me with any of these it would be really appreciated. If you answer all I will give brainliest. 1) What controls the body’s physiological responses such as a sleep-wake cycle and brave wave activity?
2) During which stage of the sleep cycle does body temperature begin to drop and heart rate slow?
3) List three important functions believed to occur during REM sleep.
4) Describe a typical dream that occurs during REM sleep.
5) Identify ways in which sleep benefits the nervous system.

Explanation:

1) The circadian rhythm is set by the suprachiasmatic nucleus of the hypothalamus, which regulates the sleep-wake cycle. The suprachiasmatic nucleus projects to the pineal gland to release melatonin, which promotes sleep.

2) stage two is also a non-REM phase and is one of the lighter stages of sleep. Even though it is a light stage, the heart rate begins to slow and the core body temperature decreases. During stage two, eye movement stops and brain waves slow with the occasional burst of waves called sleep spindles.Feb 8, 2017

3) Rapid movement of the eyes.

   Fast and irregular breathing.

   Increased heart rate (to near waking levels).

   Changes in body temperature.

    Increased blood pressure.

    Brain activity similar to that seen while awake.

4) your eyes move around quickly behind your eyelids and your brainwaves look similar to those of someone who is awake. Your breathing, heart rate, and blood pressure rise to near-waking levels.

5) During sleep, your sympathetic nervous system – which controls your fight or flight response – gets a chance to relax. Studies have shown that when we're deprived of sleep, sympathetic nervous system activity increases, which is also mirrored by an increase in blood pressure
