There are two kinds of neurons involved in the transmission of any signal through the sympathetic system: pre-ganglionic and post-ganglionic. The shorter preganglionic neurons originate from the thoracolumbar region of the spinal cord specifically at T1 to L2~L3 , and travel to a ganglion , often one of the paravertebral ganglia , where they synapse with a postganglionic neuron. From there, the long postganglionic neurons extend across most of the body. [4]

Involuntary control exists where the animal has no choice and the response to an activity or event occurs without the animal having any conscious control. Examples of the functioning of this part of the nervous system are the regulation of heart beat and circulation, digestion, and respiration. It is obvious that the animal cannot afford to have to remember to keep its heart beating, its digestive system functioning or even just to breath. The part of the nervous system that regulates such important functions is called the autonomic, or involuntary, nervous system.
