PATHOLOGY

Detailed explanation-1: -If cells are no longer needed, they commit suicide by activating an intracellular death program. This process is therefore called programmed cell death, although it is more commonly called apoptosis (from a Greek word meaning “falling off, ‘’ as leaves from a tree).

Detailed explanation-2: -Also called programmed cell death.

Detailed explanation-3: -A type of programmed cell death is observed in multicellular organisms known as apoptosis.

Detailed explanation-4: -Various stimuli can engage a non-apoptotic form of cell death called necroptosis (Degterev et al., 2005).
