Norepinephrine is indeed a neurotransmitter that plays a role in various functions including appetite regulation. The sympathetic nervous system actually increases heart rate, not decreases it, making A incorrect. The parasympathetic nervous system causes the pupil to constrict, not dilate, making B incorrect. Acetylcholine is a neurotransmitter involved in muscle activation and other functions, but it is not primarily known for its role in appetite regulation, making D incorrect.
