The series of molecular signals which triggers the apoptotic death of a cell. The pathway starts with reception of a signal, and ends when the execution phase of apoptosis is triggered. [ GOC:mtg_apoptosis ]

Term information
This term can be used to annotate gene products involved in apoptotic events happening downstream of the cross-talk point between the extrinsic and intrinsic apoptotic pathways. The cross-talk starts when caspase-8 cleaves Bid and truncated Bid interacts with mitochondria. From this point on it is not possible to distinguish between extrinsic and intrinsic pathways.
