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 in the thoracolumbar division 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. WebMay 17, 2024 · The sympathetic system dilates the pupil of the eye, whereas the parasympathetic system constricts the pupil. In some organs, opposing effects are achieved without dual innervation.
