This research was practiced to comparative investigate the distribution of sensory and motor neuron linkaged with Yangji(TE4) by using neural-tracer technology. A total 16 S-D rats were used in the present research. After anesthesia, the rats received micro-injection of 6㎕ of cholera toxin B subunit(CTB) into the relation positions of the Yangji(TE4), in the human body for observing the distribution of the linkaged sensory neurons in dorsal root ganglia(DRGs) and motor neurons in the spinal cord(C3∼T4) and sympathetic ganglia. 3 days after the micro injection, the rats were anesthetized and transcardially perfused saline and 4% paraformaldehyde, followed by routine section of the DRGs, sympathetic chain ganglia(SCGs) and spinal cord. Marked neurons and nerve fibers were detected by immunohistochemical method and observed by light microscope. The marked neurons were recorded and counted. From this study the distribution of primary sensory and motor neurons linkaged with Yangji(TE4) were concluded as follows. Yangji(TE4) dominated by spinal segments of C5∼T1, C6∼T4, individually.
