Preganglionic neurons originate from the thoracolumbar region of the spinal cord travel to a ganglion where they synapse with a  long postganglionic neuron. Preganglionic neurons release acetylcholine and postganglionic release norepinephrine, which activates adrenergic receptors on target tissues.</span>
