thrombotic strokes/cerebral thrombosis - correct answer ✔✔ artery is occluded by a plug of
material accumulating at a fixed location
embolic strokes/cerebral embolisms are caused by - correct answer ✔✔ caused by a fragment
of material that travels through the circulatory system until it reaches an artery smaller than its
own diameter, where it lodges, occluding it
