Dissection involves separation of laminar planes of which arterial wall layer?

Explanation:
Dissection creates a false channel by splitting the wall along the layered sheets inside the middle layer. The arterial wall has three layers: inner intima with endothelial lining, middle media with concentric smooth muscle and elastic lamellae, and outer adventitia. The planes that allow separation are the lamellae within the media, so the dissection occurs there rather than in the endothelium or the outer connective-tissue layer.
