I would like help with the question below. I have done a lot of research to find the best answers but am coming up with a few variations. I have chosen C, D, for sure and am questioning E, F and G. Here is why: E: there are int and ext elastic membranes in larger vessels which would lead me to believe elastic vessels but I do see int and elastic membranes when I look at images on the internet. F: I heard word for word when viewing a crash course video on the veins and arteries... G: I have also found a few areas that lead me to believe that the common iliac is elastic, but I know that the elastic arteries are those closest to the heart. I have found info showing both. Thanks for the help. I have posted this question once before with these questions but received different answers so I am posting one more time to compare. Question to Answer: Select all of the following that are TRUE of muscular arteries. a. largest diameter arteries b. subclavian artery is an example c. the tunica media has more smooth muscle than elastic fibers d. they are also referred to as distributing arteries e. they contain both the internal elastic membrane and the external elastic membrane f. proportionately, has the thickest tunica media of all vessels g. common iliac artery is an example Solution c. the tunica media has more smooth muscle than elastic fibers d. they are also referred to as distributing arteries e. they contain both the internal elastic membrane and the external elastic membrane f. proportionately, has the thickest tunica media of all vessels Muscular arteries are medium and small sized diameter arteries, muscular arteries walls are comprised of thicker smooth muscle layer and will have thick internal elastic membrane and these are known as distributing arteries. Examples of muscular arteries include the brachial, anterior tibial, and coronary arteries. It has been found that the tunica media of muscular arteries contains fewer elastic fibers and more smooth muscle cells than elastic arteries. A pronounced internal elastic membrane and external elastic membrane are distinguishing characteristics of muscular arteries. Tunica media is thicker than the tunica externa in case of muscular arteries and will have thickest tunica media of all vessels. The common iliac artery is an example of elastic artery..
