The division of coagulation in two pathways is arbitrary, originating from laboratory tests in which clotting times were measured either after the clotting was initiated by glass, the intrinsic pathway; or clotting was initiated by thromboplastin (a mix of tissue factor and phospholipids), the extrinsic pathway.
View/Edit Mouse. Intrinsic factor (IF), cobalamin binding intrinsic factor, [5] also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells (in humans) or chief cells (in rodents) of the stomach. It is necessary for the absorption of vitamin B 12 later on in the distal ileum of the small intestine. [6]
Look up intrinsic, extrinsic, or innate in Wiktionary, the free dictionary. In science and engineering, an intrinsic property is a property of a specified subject that exists itself or within the subject. An extrinsic property is not essential or inherent to the subject that is being characterized. For example, mass is an intrinsic property of ...
The distinction between intrinsic and extrinsic motivation is based on the source or origin of the motivation. Intrinsic motivation comes from within the individual and is driven by internal factors, like enjoyment, curiosity, or a sense of fulfillment. It occurs when people pursue an activity for its own sake.
Extrinsic pathway. In molecular biology, the term extrinsic pathway may refer to multiple cascades of protein interactions. The extrinsic pathway of apoptosis refers to cell death induced by external factors that activate the death-inducing signaling complex. The extrinsic pathway of blood coagulation is also known as the tissue factor pathway ...
Prothrombin time. Blood plasma after the addition of tissue factor. The gel-like structure is strong enough to hold a steel ball. The prothrombin time (PT) – along with its derived measures of prothrombin ratio (PR) and international normalized ratio (INR) – is an assay for evaluating the extrinsic pathway and common pathway of coagulation.
An intrinsic property is a property that a thing has itself, including its context. An extrinsic (or relational) property is a property that depends on a thing's relationship with other things. For example, mass is an intrinsic property of any physical object, whereas weight is an extrinsic property that varies depending on the strength of the ...
Thromboplastin. Thromboplastin (TPL) is derived from cell membranes and is a mixture of both phospholipids and tissue factor, neither of which are enzymes. Thromboplastin acts on and accelerates the activity of Factor Xa, also known as thrombokinase, [1] aiding blood coagulation through catalyzing the conversion of prothrombin to thrombin.
