The parasympathetic and sympathetic divisions of the PNS
Chapter 49, Problem 49.2(choose chapter or problem)
The parasympathetic and sympathetic divisions of the PNS (see Figure 49.8) use the same neurotransmitters at the axon terminals of preganglionic neurons, but different neurotransmitters at the axon terminals of postganglionic neurons. How does this difference correlate with the function of the axons bringing signals into and out of the ganglia in the two divisions?
