Ischemic strokes occur with a complete or partial occlusion of arteries‚ which causes a region to fall below the level needed to maintain cellular function. As a result‚ cells begin to die‚ and an infarct can develop with necrosis. During an ischemic stroke‚ there is typically an inner zone of infarction‚ with an outer region of ischemia. An infarct can be prevented if the amount of collateral circulation around the ischemic area is adequate. (Chapey‚ 1994). Medical treatment usually targets

to the actin filament forming a cross-bridge. The myosin pulls the actin towards the centre of the sarcomere creating a power stroke. A specific chemical reaction needs to occur in order for the myosin to acquire the sufficient energy to pull the actin filament. A fact from Chemistry gives a greater understanding of the chemical reactions that occur during a power stroke thus giving a greater understanding of the filament interaction from a molecular perspective.

all the signs of an ischemic stroke such as weakness of the whole left side of his body‚ which can be caused by i.e congenital diseases and strokes. The ischemic stroke was found to be located in the right middle cerebral artery (right MCA) by neurologic examination. An ischemic stroke is when a tissue or an organ cannot be supplied with blood due to i.e a blood clot in the vessel. These leads to tissue death if not treated quickly enough‚ since an acute ischemic stroke can build up in a matter of
