The sympathetic function is modulated at all levels of peripheral and central nervous system from the dorsal root ganglia (DRG), to substantia gelatinosa (SG).
At the periphery, the efferent sympathetic nerves control the circulation. The afferent sympathetic nerves are influenced by the putative effects of acetylcholine and dynorphin on one end, and the substance P (SP) on the other.
At the spinal substantia gelatinosa (SG) level of dorsal horn (DH) the superficial layers I-III receives substance P (SP) from the periphery. The deeper layers IV and V act as inhibitory layers showing high concentrations of dynorphin.
