Where is the most common site for plaque formation in the carotid arteries?

Explanation:
The most common site for plaque formation in the carotid arteries is the carotid bulb at the bifurcation where the common carotid splits into the internal and external branches. This region experiences disturbed flow and low, oscillatory shear stress, which promote endothelial dysfunction and lipid accumulation, driving atherosclerosis. The flow patterns here are more turbulent than in the straight portions, making the bulb a prime spot for plaque to develop. While plaques can occur elsewhere, the bifurcation site is by far the most typical location.
