The preganglionic neuron in both the sympathetic and parasympathetic nervous systems always release Ach which is always inhibitory True False

Postganglionic neurons in the parasympathetic division of the autonomic nervous system release at their synapses.

In which way are the sympathetic and parasympathetic divisions of the autonomic system similar?Multiple ChoiceBoth utilize two neurons per message.In both, the preganglionic neuron is shorter than the postganglionic neuron.Both use norepinephrine as their neurotransmitter.Both arise from the sacral spinal nerves.Both are associated with the relaxed state (rest-and-digest).

Which of the following statements about the sympathetic nervous system is true?Group of answer choicesThe sympathetic nervous system uses acetylcholine as its sole neurotransmitter.All of these statements are true.The sympathetic nervous system has long preganglionic neurons and short postganglionic neurons.None of these statements are true.The sympathetic nervous system controls the rest-and-digest response.
