Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following arterial layers is full of elastin protein?
A
Tunica media
B
Tunica intima
C
Tunica externa
D
Epithelial layer
Explanation: 

Detailed explanation-1: -Elastic arteries are those nearest the heart (aorta and pulmonary arteries) that contain much more elastic tissue in the tunica media than muscular arteries.

Detailed explanation-2: -8.5. Rather, the media is dominated by nearly circumferentially aligned layers of smooth muscle cells with interspersed collagen fibers and small amounts of elastin fibers.

Detailed explanation-3: -ELASTIC ARTERIES In the aorta, the tunica media constitutes the greater part of the vessel wall. It is made up of multiple elastic lamellae alternating with thin layers of circularly oriented smooth muscle .

Detailed explanation-4: -The arterial tunica media primarily consists of multiple layers of circumferentially oriented SMCs and ECM, including collagen, elastin (ELN), and proteoglycans. The ECM provides structural support as well as elasticity to the blood vessel.
