A

Non-REM sleep

3
Q

During this stage muscles are relaxed, but muscle tone is maintained respirations are even and blood pressure, temperature, urine formation and oxygenation consumption decrease. Sleep-walking and bed-wetting(enuresis) are most likely to occur. Dreams are realistic.

A

N3

4
Q

Closely resembles wakefulness in the EEG and is characterized by very low or absent muscle tone. It compromises about 20-25% of a night’s sleep. Respirations are irregular and oxygen consumption increases. BP and pulse show variations and fluctuate rapidly.

A

REM sleep
