== Study Questions ==
* <spoiler text="What is the cause of atheromatous emboli?">Ulcerated or complex atherosclerotic plaques rupture and release cholesterol and other material into the blood stream. These materials lodge in vessels downstream. Ulceration or rupture of atherosclerotic plaques is part of the normal progression of atherosclerosis.</spoiler>
* <spoiler text="What happens when atherosclerotic material embolizes?">When the atherosclerotic plaque ruptures collagen, cholesterol esters and necrotic material are exposed to the blood stream. This initiates thrombus formation. So, in addition to the cholesterol embolizing to distal vessels, thrombosis is also initiated and can obstruct vessels.</spoiler>
* <spoiler text="What other types of material can embolize and cause clinical problems?">Probably 99% of all emboli are thromboemboli. Other materials that can embolize are: fragments of bone or bone marrow, fat, tumor cells, foreign bodies such as bullets, and bubbles of air or nitrogen.</spoiler>
