45
Where does a plaque generally exist?
Above the internal elastic lamina (between lamina and inner media).
46
2 "models" used to describe how atherosclerosis develops
Hemodynamic model - due to lesions near bifucations. Circulating lipids - accumulation of choleserol which is metabolized by Mo and a fatty streak is made.
47
False aneurysm
Defect thru the wall of a vessel that communicates w/ and extravascular hematoma that communicates with the lumen of the vessel. Creates a pulsating hematoma.
48
Atherosclerosis causes ischemia of the ______ media
Inner
49
HTN causes ischemia of the ______ media
Outer
