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 and refers to a cascade of enzymatic reactions resulting in blood clotting and is done with the addition of injured tissue cells.

a number of extracurricular molecules is specialised to induce apoptosis.These extracurricular signals molecules bind with cell surface receptors (termed death receptors).
