| Abstract: | WGA-HRP was applied to the pelvic and pudendal nerves of Sprague-Dawley and Wistar rats to compare the segmental levels of the resulting labeling. L6 and S1 were the segme its at which the sacral parasympathetic nucleus and the denser primary afferents occurred in Sprague-Dawley rats. The levels found in Wistar rats were S1 and S2, Thus indicating a disparity between both strains of rats in the spinal level of the sacral parasympathetic nucleus and the primary afferents. |
