Abstract:
The two-way projection of the intrinsic cardiac neurons in the rat has been studied by means of CB-HRP retrograde tracing and double-labelling with fluorescent tracers. CB-HRP was injected into the right stellate ganglian of the 20 rats. CB-HRP positive neurons were found in the intrinsic cardiac ganglia, moreover, most of the labelled cells localized in the ganglia which were nearby the epicardium of posterior wall of the atria and the root of large vessles. Bb and PI were injected the right stellate ganglia and the wall of the cardiac ventricle of 30 rats respectively, PI-Bb double labelling neurons were found in the posterior wall of the atria for the first time. The present study demonstrated that a few of intrinsi ccardiac neurons give off two long processes, one of which projects to the ventricle, and the other one extends to the stellate ganglion. They may be sensory and may participate the composition of vegetative nervous reflex pathway of heart outside CNS.
