MEDICAL PHYSIOLOGY

Detailed explanation-1: -Ischemic Stroke-An ischemic stroke occurs when the supply of blood to one or more regions of the brain is suddenly cut off or interrupted. It is similar to a heart attack, but it occurs in the brain and causes a lack of oxygen to millions of neurons and other brain cells fed by the blocked artery.

Detailed explanation-2: -An ischemic stroke occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes. A stroke is a medical emergency, and prompt treatment is crucial. Early action can reduce brain damage and other complications.

Detailed explanation-3: -Stroke is a sudden interruption of the blood supply to the brain. Most strokes are caused by an abrupt blockage of an artery (ischemic stroke). Other strokes are caused by bleeding into brain tissue when a blood vessel bursts (hemorrhagic stroke).
