The image is a histological cross-section of an artery affected by atherosclerosis. ### Description: - **Outer Layer (Tunica Adventitia):** The dark purple outermost layer of the artery wall. It provides structural support and protection. - **Middle Layer (Tunica Media):** Located beneath the adventitia, this layer is slightly lighter in color and is responsible for maintaining blood pressure and flow through muscle contractions. - **Inner Layer (Tunica Intima):** The innermost thin layer visible as a darker line adjacent to the plaque. It consists of endothelial cells and connective tissue. - **Atherosclerotic Plaque:** The central portion of the cross-section, showing a buildup of cells, lipids, and extracellular matrix material. This plaque narrows the arterial lumen, impeding blood flow and increasing the risk of cardiovascular events. ### Educational Notes: - **Atherosclerosis** is a condition where arteries become narrowed and hardened due to plaque accumulation. This image serves to show the structural changes in the arterial walls associated with the disease. - **Histological Staining** helps differentiate between different tissue types, allowing for detailed analysis of structural changes.
