to around people from this stage.
The three (used to be four) main phases of NREM sleep - correct answer ✔✔Stage 1 is a low-
voltage high frequency sleep
Stage 2 looks like a fixed-spindle and it looks like an ink blot with a k-complex
Stage 3 is slow-wave sleep or deep sleep
During stage 1 of sleep - correct answer ✔✔During stage 1 of sleep, or light sleep, we drift in
and out of sleep and can be awaken very easily. Our eyes move very slowly and muscle activity
slows.
hypnic myoclonia - correct answer ✔✔Muscle contractions often produced by a sensation of
starting to fall during stage 1 of sleep.
What happens during stage 2 of sleep - correct answer ✔✔the eye movement stops and the
brain waves slow down
In stage 3/4 of sleep - correct answer ✔✔the extremely slow brain waves appear, and it is very
difficult to take someone up during these stages.
What happens to our sleep as we age - correct answer ✔✔Throughout your life span you spend
different fractions of the night in different levels of sleep.

decreases
By morning - correct answer ✔✔nearly all sleep time is in stage 1, 2, and REM sleep
Explain a typical nightly Hypnogram - correct answer ✔✔
