Neurons within the hypothalamus control the activity of neurons in the intermediolateral cell column (IML) of the spinal cord. Neurons within IML project to neurons within ganglia located close to the spinal cord. Neurons within the ganglia project to target tissues. Acetylcholine (ACh) is the neurotransmitter released at synapse in ganglion and norepinephrine (NE) is released at target tissues. In addition, neurons within IML project directly to the adrenal medulla where they release ACh which stimulates release of epinephrine (E) into blood.
