This image illustrates a longitudinally-sectioned arteriole

Note the distinctive appearance of endothelial and smooth muscle nuclei.  Because smooth muscle fibers encircle the vessel, when the arteriole is sectioned longitudinally, the elongated (cigar-shaped) nucleus of each muscle cell is cut in cross-section and thus appears small and round.

The tissue around the vessel is fibrous connective tissue of deep dermis (skin).
