What term is used for the formation of a blood clot in an artery supplying part of the brain?

The correct term for the formation of a blood clot specifically in an artery supplying part of the brain is cerebral thrombosis. This condition occurs when the blood flow is obstructed by a clot that forms within the blood vessels in the brain, which can lead to a stroke.

Cerebral thrombosis is a critical concern because it interrupts the blood supply to brain tissues, potentially resulting in severe neurological damage. This term emphasizes the location and causative factor, highlighting that the clot is formed in situ (in the artery itself), leading to the cessation of blood circulation in that area of the brain.

In contrast, cerebral embolism refers to a clot that originates from elsewhere in the body and travels to the brain, obstructing a blood vessel there. Myocardial infarction is related to a blockage in the coronary arteries supplying the heart muscle, while carotid blockage pertains to issues in the carotid artery that may affect cerebral blood flow but does not specifically define the formation of a clot. Thus, cerebral thrombosis accurately describes the scenario outlined in the question.
