When foam cells accumulate in a significant amount with-
in the arterial wall, they form ______ . What is then re-
leased?
Growth factors released released in atherogenesis stimu- smooth muscle cell proliferation; produce collagen and
late _______ , which ________ . migrate over the fatty streak to form a fibrous plaque.
Plaques that have ruptured are called ______ . complicated plaques
inflammatory activation of proteinases, apoptosis of cells
Plaque rupture occurs because of the ______ . within the plaque, and bleeding within the lesion (plaque
hemorrhage).
The underlying tissue is exposed and causes platelet ad-
hesion, initiation of the clotting cascade, and rapid throm-
What happens once a plaque ruptures?
bus formation that can suddenly occlude the vessel, re-

A fibrous plaque that has calcified, protruded into the
