Quizplus · Accepted Answer

Preganglionic neurons of the autonomic nervous system are located in both the brain stem and the lateral gray horns of the spinal cord. The brain stem houses preganglionic neurons of the cranial nerves, while the lateral gray horns of the spinal cord house preganglionic neurons of the sympathetic nervous system. The posterior gray horns of the spinal cord house sensory neurons, and the anterior gray horns of the spinal cord house motor neurons.
