Parasympathetic postganglionic cell bodies
WebParasympathetic preganglionic neurons have cell bodies located in the brainstem and in the sacral (toward the bottom) spinal cord, as shown in Figure 2. The axons of the preganglionic neurons release acetylcholine on the postganglionic neurons, which are generally located very near the target organs. WebQuestion 1 Where are the cell bodies of postganglionic neurons of the parasympathetic neurons located? Selected Answer: Answers: c. They are located in sympathetic trunk ganglia beside the spinal cord. A. They are located in dorsal root ganglia close to the spinal cord. B. They are located in collateral ganglia anterior to the spinal cord. c.
