Question 5

Describe the human

sleep cycle

Answer 5

• 5 stages
• First four stages of sleep are NREM (90 minutes)
• REM sleep is final stage (10 minutes)

-You pass through this 100 minute cycle 4 to 6 times
a night

-As the night progresses, the amount of time you
spend in deep sleep (stages 3 and 4) decrease and
the amount of time you spend in REM sleep
increases

Question 6

Differences
between REM
and NREM

Answer 6

NREM
-reduced muscle tension throughout body

• minimal movement (body capable, but brain rarely requests it to move)
• low temp. & low energy consumption
• heart rate, respiration, and kidney function slow down

REM
-EEG indistinguishable from awake state

• high oxygen consumption
• increased and irregular heart & respiration rates
• muscle atonia
• body temp. drops

-dreams are hallucinatory, emotional, narrative, and with frequent
movements
