Explanation:
The cell bodies of preganglionic neurons of the parasympathetic division are present in the nuclei of four cranial nerves in the brainstem. These four cranial nerves are III, VII, IX, and X. Likewise, some of the cell bodies of the preganglionic neurons of the parasympathetic division are present in the lateral gray matter of the second to fourth sacral segments of the spinal cord. Therefore, the parasympathetic division is also known as the craniosacral division. The axons of the parasympathetic preganglionic neurons are called craniosacral outflow.
