Total cell numbers and neuronal diameters of L6 and S1 dorsal root ganglia, which provide a sensory innervation to pelvic viscera were determined in young adult (3-months-old) and compared to those in old (24-months-old) male rats. Two methods of cell counting, serial (section) reconstructions and total profile counting, were used in this study. Our data showed that the total number of L6 and S1 dorsal root ganglia (DRG) cells and their diameters remain essentially constant from 3 to 24 months… CONTINUE READING
