The correct answer is thoracolumbar origin, short preganglionic fiber, ACh release at ganglion, long postganglionic fiber, NE release at effector.

The sympathetic system consists of short pre-ganglionic and long post-ganglionic neurons. 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.
