Verified step by step guidance

Understand the role of the parasympathetic division in the autonomic nervous system, which is responsible for 'rest and digest' activities.

Recognize that neurotransmitters are chemical messengers that transmit signals across synapses from one neuron to another.

Identify the primary neurotransmitter associated with the parasympathetic division, which is acetylcholine. This neurotransmitter is involved in slowing the heart rate, increasing intestinal and gland activity, and relaxing sphincter muscles.

Differentiate acetylcholine from other neurotransmitters such as serotonin, norepinephrine, and epinephrine, which are not typically associated with the parasympathetic division.

Recall that acetylcholine is released at both the preganglionic and postganglionic synapses in the parasympathetic division, making it the key neurotransmitter for this part of the autonomic nervous system.
