Question

put the steps into the correct order to trace an embolic stroke.
1 dead neurons no longer fire, resulting in weakness and/or pa
2 inflammatory process begins to help the body dissolve the cl edema in the area
3 plaque or clot breaks free from the wall of the heart or caroti
4 embolus passes through the carotid artery into the brain and b lodged in a smaller arteriole
5 edema causes increase in local pressure and even more nerve
6 lack of blood flow to the tissue served by the arteriole results i eventual cell death

Explanation:

1. The process starts with the origin of the embolus: a plaque/clot breaking loose from the heart or carotid.
2. The embolus travels through the carotid artery to the brain, where it gets stuck in a small arteriole.
3. The blocked arteriole cuts off blood flow to the brain tissue it supplies, leading to cell death.
4. Dead neurons stop functioning, causing physical symptoms like weakness/paralysis.
5. The body initiates an inflammatory response to dissolve the clot, which causes local edema.
6. This edema increases pressure in the area, damaging more nerve tissue.

Answer:

1. 3. Plaque or clot breaks free from the wall of the heart or carotid
2. 4. Embolus passes through the carotid artery into the brain and becomes lodged in a smaller arteriole
3. 6. Lack of blood flow to the tissue served by the arteriole results in eventual cell death
4. 1. Dead neurons no longer fire, resulting in weakness and/or paralysis
5. 2. Inflammatory process begins to help the body dissolve the clot, causing edema in the area
6. 5. Edema causes increase in local pressure and even more nerve damage
