Segmental distribution of afferent fibres in the left inferior cardiac nerve of the cat studied by anterograde transport of horseradish peroxidase.
The segmental projection of afferent fibres in the left inferior cardiac nerve of the cat was studied by using the anterograde transport of horseradish peroxidase (HRP). HRP-positive cell bodies were detected in ipsilateral dorsal root ganglia from segments T1 to T7. No labelled neurones were found at segments C8 and T8. The total number of labelled neurones ranged from 157 to 535 neurones in individual experiments. The majority of neurones (70-88%) were localized in the dorsal root ganglia of segments T2-T4. Labelled neurones were oval shaped, and most neurones had a long axis in the range from 20 to 40 microns.
