Arteriole

This electron micrograph shows a portion of the wall of an arteriole with two layers of smooth muscle cells. Some of the space between the smooth muscle cells is due to artifactual shrinkage during fixation. The endothelial cells lie immediately above the internal elastic lamina and a portion of the tunica adventitia with fibroblast processes is visible in the lower left. 10,000x
