Q

What kind of vessel is A pointing to?

A

An elastic artery (like the aorta)

Elastic lamellae interrupt smooth muscle in the tunica media

Q

What kind of vessels are the arrows pointing to?

What is unusual about them?

(Tissue = penis)

A

Muscular arteries

They are unusual because they have inner, longitudinal smooth muscle fibers under the tunica intima

Q

What kind of vessel is B pointing to?

A

A large vein

Q

What structure within the vessel is C pointing to?

A

Internal elastic membrane

Q

What kind of cell is E pointing to?

A

Smooth muscle cells in the tunica media

The vessel is an elastic artery; smooth muscle in the tunica media is interrupted by elastic lamellae

Q

What structures is D pointing to?

A

(Fenestrated) elastic lamellae

The vessel is an elastic artery; smooth muscle in the tunica media is interrupted by elastic lamellae

Q

What kind of vessel is shown in this image?

A

Elastic artery (ex: Aorta)

Q

Which structures are labled by B?

A

Longitudinal bundles of smooth muscle in the adventitia

(The structure is a large vein, like the vena cava)

Q

What kind of vessel is B pointing to?

A

Muscular artery
