CARDIOVASCULAR IMAGE INDEX
- The endothelium of this small artery is a simple squamous epithelium, visible here only as a "dotted line" of nuclei of endothelial cell nuclei, 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.
- Smooth muscle fibers form the media of this small artery.
- Immediately surrounding the artery is connective tissue of adventitia. This is not a distinct layer but merges with surrounding connective tissue, here labelled as collagen.
