The common pathway starts with the activation of factor X by way of the intrinsic pathway, the extrinsic pathway, or both. Factor X is manufactured in the liver, and is vitamin K dependent.
The common pathway is sometimes referred to as the final common pathway or thrombin pathway, and factor X is also referred to as either Stuart-Prower Factor or thrombokinase.
The common pathway is circled in red in the image below.
