Question

match the sleep stages to their descriptions by dragging each circle in the first column to the appropriate circle in the second column. when all the circles have been placed, select the check answer button. nrem - 1 stage with moderately slow waves interspersed with bursts of rapid activity nrem - 2 stage of sleep in which the brain and eyes are highly active, and vivid dreams occur nrem - 3 stage of light sleep; transition between wakefulness and sleep rem stage of deep sleep consisting almost entirely of large slow waves

Explanation:

• NREM - 1: It is the initial stage of sleep, acting as a transition between being awake and sleeping, so it matches "stage of light sleep; transition between wakefulness and sleep".
• NREM - 2: In this stage, brain waves show moderately slow waves with bursts of rapid activity (like sleep spindles), so it matches "stage with moderately slow waves interspersed with bursts of rapid activity".
• NREM - 3: This is a deep sleep stage with large, slow delta waves, so it matches "stage of deep sleep consisting almost entirely of large slow waves".
• REM: During REM sleep, the brain and eyes are very active, and this is when vivid dreams typically occur, so it matches "stage of sleep in which the brain and eyes are highly active, and vivid dreams occur".

Answer:

• NREM - 1: stage of light sleep; transition between wakefulness and sleep
• NREM - 2: stage with moderately slow waves interspersed with bursts of rapid activity
• NREM - 3: stage of deep sleep consisting almost entirely of large slow waves
• REM: stage of sleep in which the brain and eyes are highly active, and vivid dreams occur
