WebApoptosis can happen through the extrinsic pathway, whereby environmental conditions signal to the cell that it must die. In contrast, the intrinsic apoptotic pathway happens when damage inside the cell triggers cell death. When studying apoptosis, it can be important to consider which pathway is induced. German scientist Carl Vogt was first to describe the principle of apoptosis in 1842. In 1885, anatomist Walther Flemming delivered a more precise description of the process of programmed cell death. However, it was not until 1965 that the topic was resurrected. While studying tissues using electron microscopy, John Kerr at the University of Queensland was able to distinguish apoptosis fro…
