Question

Which one of the following is incorrect for 'atherosclerosis'?

• A. Constriction of arterial lumen reduces the blood flow.
• B. Loss of dilation ability of the arterial wall and its rupture.
• C. Cholesterol deposition at the inner wall of the artery.
• D. Proliferation of the vascular muscles.

Answer 1

The correct option is B Loss of dilation ability of the arterial wall and its rupture.

Atherosclerosis is a disease of the arteries characterized by the deposition of fatty material on their inner walls, due to which artery wall thickens. Atherosclerosis is due to deposition of cholesterol and proliferation of vascular muscle in presence of Platelet Derived Growth Factor (PDGF).

So, the correct answer is 'Loss of dilation ability of the arterial wall and its rupture'
