Intracardiac nerve fibres from the interatrial septum were studied quantitatively and qualitatively by electron microscopy of transversely sectioned nerve bundles in male Wistar rats of 4 and 24 months. No significant changes were found in the myelinated fibre diameters, myelinated axon diameters, myelin sheath thicknesses, g ratios, myelinated fibre areas, unmyelinated axon diameters and unmyelinated axon areas. However, there was evidence of structural changes to the nerve fibres and Schwann… CONTINUE READING
