The process of controlling/stopping bleeding from a broken vessel; platelets are the main component of hemostasis by working with the plasma protein fibrinogen to form a blood clot.
Are also called thrombocytes, platelets are actually cell fragments of bone marrow cells called megakaryocytes. Platelets are used to form blood clots to control hemostasis.
When blood flow is obstructed to an area of the brain causing brain tissue to become ischemic; if blood flow is not immediately restored brain damage will ensue.
An enzyme in the blood that plays a critical role in hemostasis by converting the plasma protein fibrinogen into fibrin; fibrin secures platelets as they plug a damaged vessel (platelet plug) and the end result is a clot.
The formation of a blood clot within a vessel which obstructs blood flow through the vessel.
