The spinal sensory component of the ganglia of the sympathetic nervous system

Summary The author studied the sources of the spinal sensory fibers of the celiac, stellate and superior cervical sympathetic ganglia.These ganglia were removed in cats and in 8–19 days all the cervical thoracic and lumbar spinal ganglia were studied in serial sections to reveal retrograde changes in the neurones.It was established that the neuron processes of the spinal ganglia C₅ and L₁ of the ipsilateral side pass through the celiac ganglion. The bulk of these neuroneslies in the spinal ganglia D₇-L₃. The neurone processes of the spinal ganglia C₂-L₄ pass through the stellate ganglion, but mainly-C₇-D₅; the neurone processes of the spinal ganglia C₂-D₄ pass through the superior cervical sympathetic ganglion.The neurone processes of the spinal ganglia of the contralateral side pass through all the sympathetic ganglia mentioned.(Presented by Active Member AMN SSSR V.
