Verified step by step guidance1
Understand the role of the autonomic nervous system (ANS) in regulating involuntary body functions such as heart rate, digestion, and respiratory rate.
Recognize that the ANS is divided into two main branches: the sympathetic and parasympathetic nervous systems.
Identify that neurotransmitters are chemical messengers used by neurons to communicate with each other and with muscles or glands.
Learn that acetylcholine is the primary neurotransmitter released by parasympathetic neurons, which generally promote 'rest and digest' activities.
Understand that norepinephrine (also known as noradrenaline) is the primary neurotransmitter released by sympathetic neurons, which generally promote 'fight or flight' responses.
