REM sleep includes which of the following?

REM sleep includes which of the following?

• A. Dreaming and Paralysis
• B. Deep Sleep
• C. Slow-Wave Activity
• D. Dreaming Without Paralysis

Answer: (A)

REM sleep is defined by vivid dreaming combined with muscle atonia. During REM, the brain shows wake-like activity with rapid eye movements, but most of the body's skeletal muscles are inhibited to prevent acting out dreams. This paralysis is a hallmark that sets REM apart from deep, slow-wave sleep, which features delta waves and little dreaming content. While dreams can occur in non-REM stages, they’re typically less vivid and do not include the characteristic REM-level muscle atonia. So the combination of dreaming and paralysis best describes REM sleep.
