A
Tunica media
4

A
- Tunica intima
- Internal elastic lamina
- Tunica media
- External elastic lamina
- Tunica adventitia
7
Q
How do artery and vein walls differ histologically?
A
Veins
- Thinner wall altogether
- Thin adventitia
- Thin media
Arteries
- Thick wall
- Thick adventita
- Thick dense media
8
Q
Which of these is an elastic and which is a muscular artery and how can you tell?
A
A = elastic artery
- Elastin died purple and lots of it in tunica media
- Thinner tunica adventitia
- Thicker tunica intima
B = muscular artery
- Less elastin
- Thicker tunica adventitia
- Thinner tinica intima
9
Q
What is similar about the tunica adventitia of both elastic and muscular arteries?
A
- Contain vasa vasorum (vessels of the vessels)

- Conducting
11
