Answer to Question 2

Correct Answer: 1,2,3
Rationale 1: The basic unit of the autonomic nervous system is a two-neuron chain. The first neuron, called the preganglionic neuron, originates in the central nervous system.
Rationale 2: The preganglionic neuron connects with the second nerve in the autonomic nervous system two-neuron chain through the ganglia, which contains the postganglionic neuron.
Rationale 3: Autonomic messages must cross the synaptic cleft.
Rationale 4: Acetylcholine is the neurotransmitter released at cholinergic receptors.
Rationale 5: Dopamine is a neurotransmitter within the limbic system and hypothalamus and not the autonomic nervous system.
