5.8 Artery

Version française

Transverse section of a large artery stained with Verhoeff’s method.

This vessel shows three distinct layers, or tunica: the intima (I), the media (M) and the adventitia (A).

The intima is composed of an endothelium (difficult to see at this magnification) applied to the internal elastic lamella (arrowhead).

The media is composed of circularly arranged smooth muscle cells and of a few elastic fibres.

The thick adventitia does not contain muscle cells but is composed of elastic fibres and lamellae (black) and collagen fibres (pink).

Stain: Verhoeff
Magnification: ×250
