A fatty deposit found in the inner lining of an artery is known as what?

Explanation:
The main idea is distinguishing the specific lipid plaque from the disease it signals. The fatty deposit that forms in the inner lining of an artery (the tunica intima) is called an atheroma. This plaque is what contributes to atherosclerosis, the process of arteries becoming narrowed and stiff due to plaque buildup. So the deposit itself is an atheroma, while atherosclerosis describes the overall condition. The other terms relate to different things—cardiac hypertrophy is enlargement of the heart muscle, and bradycardia is a slow heart rate.
