CARDIOVASCULAR IMAGE INDEX
- The intima of the small artery is visible only as a "dotted line" of nuclei of endothelial cells, exactly at the edge of the arterial lumen. These nuclei look round rather than flat because post-mortem contraction of smooth muscle in the media has caused longitudinal wrinkles in the endothelium.
- The internal elastic lamina is inconspicuous.
- The media is the thickest, most conspicuous layer, in which nuclei of individual smooth muscle fibers are clearly visible.
- The adventitia is not a distinct layer but merges with surrounding connective tissue.
