Which term matches REM?

Which term matches REM?

• A. REM
• B. Fragmented Sleep
• C. Delayed Onset of Sleep
• D. NREM Stage III IV

Answer: (A)

REM sleep is defined by rapid eye movements, dreaming, and brain activity that resembles wakefulness, along with a temporary loss of voluntary muscle tone. It cycles about every 90 minutes and tends to occupy more time toward the later night. This specific combination of rapid eye movements and dreaming distinguishes REM from the other descriptions: deep non‑REM sleep (NREM III/IV) features slow-wave brain activity with little eye movement, while fragmented sleep and delayed onset of sleep describe patterns or problems in sleep timing rather than a distinct stage. So the term that matches REM is the one that names this rapid eye movement sleep stage.
