How is the extrinsic pathway activated
WebTissue Factor Pathway (Extrinsic Pathway) The main role of the tissue factor pathway is to generate a “thrombin burst”, a process by which thrombin, the most important constituent of the coagulation cascade in terms of its feedback activation roles, is … Webthat both FIX and FXI are activated by FXIIa-independent mechanisms, as depicted in Fig. 2B. This revised model of coagulation predicts that the extrinsic pathway is required for initiating thrombin generation and fibrin formation, while FXIa activation of FIX is primarily involved in sustaining thrombin generation.
