Question

Quizplus · Accepted Answer

The preganglionic neurons that stimulate the adrenal medulla are located in the lower thoracic region of the spinal cord. Specifically, they are found in the intermediolateral cell column of the spinal cord segments T5-T11. These neurons release acetylcholine, which signals the adrenal medulla to secrete epinephrine and norepinephrine.
