[Efferent sympathetic preganglionic and afferent spinal transit pathways of the cat stellate ganglion]

Using a technique of retrograde axonal transport of horseradish peroxidase, labeled neurons were detected in the intermedialateral nucleus (pars principalis and pars funicularis), intercalatous spinal nucleus, and in the ventral horns of the spinal cord in cats. Afferent spinal transit pathways pass in all the above branches as well as the vertebral nerve. Bodies of the labeled neurons with branches passing in the vertebral nerve are located in the T2-T7 spinal ganglia, whereas those with branches passing in other nerves--are located in the C8-T8.
