Fig. 6.

Electron microscopic image of the cross section of a left aortic depressor nerve from age-matched adult female (A) and male (B) Sprague-Dawley rats. The aortic depressor nerve (ADN) diameter was significantly smaller (P < 0.01) across the population of age-matched female (n = 6) compared with male (n = 6) Sprague-Dawley rats. See (Morphological differences between aortic depressor nerves of male and female rats) for summary and comparison of morphometric measures. Magnification, ×1500; scale bar, 5.0 μm for both images.
