Question

Quizplus · Accepted Answer

Apoptosis is the programmed cell death which occurs when a cell activates its own genetic program to commit suicide. It is a controlled process where the cell membrane remains intact and the cellular contents are neatly packaged and then phagocytized by neighboring cells or by macrophages. Necrosis, on the other hand, is an uncontrolled process of death that occurs due to external factors like injury, infection or toxins. An infarct is an area of tissue death caused by a lack of blood supply due to obstruction of blood flow. Gliosis is the process of proliferation of glial cells that occurs in response to injury or insult to the brain. "A shame" is not a relevant term used in biology.
