Size distribution of myelinated fibers (upper panels) and respective axons (lower panels) of proximal (left panels) and distal (right panels) segments, of the right sural nerve of young (20 weeks old) male and female SHR and WKY. Note that myelinated fibers distributions are bimodal while axon distributions are unimodal. Note also a reduction of the frequency of the smaller fibers and axons in SHR nerves. No differences were observed between sides (One Way Analysis of Variance (ANOVA) on Ranks test).
