Explanation:
Detailed explanation-1: -The preganglionic neurons of the sympathetic system arise from the thoracic and lumbar regions of the spinal cord (segments T1 through L2). Most of these preganglionic axons are short and synapse with postganglionic neurons within ganglia found in the sympathetic ganglion chains.
Detailed explanation-2: -Postganglionic neurons of the sympathetic nervous system use norepinephrine and epinephrine. Although, there are exceptions to this as described below. Norepinephrine gets released by postganglionic neurons of the sympathetic nervous system, which binds to and activates adrenergic receptors.
