Arterial wall, elastin stain
CARDIOVASCULAR IMAGE INDEX
In this specimen, elastic tissue is colored deep purple, collagen is pale pink and cytoplasm (in smooth muscle and nerve) is purple.
Note the distribution of elastin in the wall of this artery.
- A continuous sheet of elastin comprises the internal elastic lamina (white highlight in image at right).
- Scattered elastic fibers characterize the adventitia.
The intima consists of little more than endothelium, barely visible between the internal elastic lamina and the lumen.
