Fig. 5From: Age-related morphological regression of myelinated fibers and capillary architecture of distal peripheral nerves in ratsComparison between the young and elderly groups in capillary diameter and microvascular branch points of the intra-tibial nerve. a Mean capillary diameter of the elderly was significantly smaller in comparison to that of the young group (P < 0.01). b The mean number of microvascular branch points for the elderly group was significantly decreased in comparison to that observed for the young group (P < 0.01). Values are presented as mean ± SEM. ** P < 0.01, young versus elderlyBack to article page
