which statements about sleep are true?
□ it is a reversible state of unconsciousness.
□ it is a state during which the body will not respond to any stimuli.
□ it is characterized by inhibition of muscular activity.
□ it is essentially a short comatose phase.

Explanation:

• "It is a reversible state of unconsciousness": Sleep is reversible (we wake up), and involves reduced consciousness, so this is true.
• "It is a state during which the body will not respond to any stimuli": Sleepers can respond to stimuli (e.g., loud noise wakes them), so this is false.
• "It is characterized by inhibition of muscular activity": During sleep, especially REM, muscle atonia (inhibition) occurs, and even in non - REM, muscle activity is reduced, so this is true.
• "It is essentially a short comatose phase": Coma is irreversible and different from sleep, so this is false.

Answer:

A. It is a reversible state of unconsciousness, C. It is characterized by inhibition of muscular activity
