So here we have an example problem that says to label each of the diagrams below with their corresponding type of artery. Notice that we've got these three images, and we need to label them either as an elastic artery, muscular artery, or arteriole. Now, taking a look at this image on the far right, one thing that stands out to me is the vast amounts of smooth muscle in its tunica media. This large amount of smooth muscle tells me that this is likely going to be a muscular artery. So we can label this image on the far right as option b to mark it as a muscular artery, and then we can cross off muscular artery since we've already labeled it.
Now, looking at this next vessel, that you can see here, notice that it is relatively thick compared to this next vessel wall. What that tells me is that this one in the middle must be the elastic artery, especially since it has the internal and external elastic lamina structures, those yellow layers within the wall here. So we can go ahead and label this middle structure as answer option a to label it as an elastic artery, and then we can cross that off.
And then, of course, that means that this final image on the far left over here must be the arteriole, so we can label it as c. So that concludes this example problem, and I'll see you all in our next video.
