Arteriole
This image shows two arterioles along with a venule. Arterioles are classified by having 1-2 layers of smooth muscle in their tunica media. The larger arteriole on the left has two layers of smooth muscle cells, whereas the one on the right has only a single layer. A thin internal elastic lamina is present in larger arteriole. 1000x
