Ultrastructural Morphometry of the Aortic Depressor Nerves and Extrinsic Renal Nerves: Similarities and Differences between Mice and Rats

Comparisons of morphometric ultrastructural parameters of the aortic depressor nerve and extrinsic renal nerve between Wistar rats and C57BL/6J mice suggest physiological differences on the fast conduction fibers between species, with possible different functional role.
