TODO - note terminological problems. WP says tunica external layer of blood vessel. FMA says tunica externa = adventitia, and is FMA adventitia covers other kinds of vessels. Here we opt for a lengthier name that attempts to disambiguate. There is no precise FMA equivalent, as FMA has tunica externa of arteries, veins, genital ducts etc as siblings
