Apoptosis is cell death via shrinkage, whereas oncotic necrosis is cell death via swelling.
The term necrosis was used for cell death before these two different processes (shrinkage and swelling) were discovered. For this reason, it is still sometimes used to refer to both apoptosis and oncotic necrosis. However, necrosis is also sometimes used to mean only cell death via swelling.
To avoid confusion, it is best to use the terms apoptosis and oncotic necrosis (and not just 'necrosis').

How do human cells die?
by apoptosis and necrosis
What is necrosis comonly known as?
Unplanned cell death, opposite of apoptosis.
What is the difference between necrosis and ischemia?
necrosis is death of cells with underlying/ or death of cells that cause inflammation. necrosis has to have an underlying injury. ischemia is decreased blood supply to tissues/ cells due to obstruction/ constriction of vasculature - indeed, this is an injury, and can lead to necrosis of cells if not resolved quickly! Note that apoptosis is programmed cell death - i.e. nucleus control is involved, and there is no inflammation - it is clean cell death! this is awesome.
Does brain trauma injury produce necrosis or apoptosis brain cell damage?
Brain trauma can lead to cell death, necrosis. Apoptosis is planned cell death, like under fetal development, so never leads to this option.
What is the function of a caspase?
Caspases, also known as cysteine-aspartic proteases are a family or cysteine proteases that play an essential role in apoptosis, necrosis and inflammation. Capsases are essential in cells for apoptosis.
What is fatty necrosis?
Fat necrosis is one of many types of necrosis. Necrosis is cell death with inflammation (different from apoptosis, which is without inflammation). Fat necrosis occurs in two forms. 1. Traumatic fat necrosis is the result of trauma. Cellular damage to fat-rich organs, such as the breasts, can lead to necrosis of the adipocytes. 2. Fat necrosis as a result of acute haemorrhagic pancreatitis. In this case, damage to the pancrease releases lipolytic enzymes into the blood, causing damage, and eventual necrosis of adipocytes.
Is cell autolysis bad?
cell autolysis may be result of inhury and unwanted when it is termed necrosis or it may be programmed when its called apoptosis
What is the difference between apoptosis and cancer?
Apoptosis-is mass cell death which kills and stops bodily functions and homeostasis to repair deadcells.Cancer-Uncontrolable cell growth or amount.
What is the medical term meaning Death of heart tissue?
The term for tissue death is either necrosis or apoptosis, depending on the situation. Apoptosis is preprogrammed tissue death, while necrosis is not preprogrammed. An infarct is an area of tissue that has died due to lack of blood supply.
What is the term used for the death of neurons?
There are two terms: necrosis and apoptosis. The latter is a special case as it is energy-dependent. It is also referred to as 'programmed cell death'; and somtimes 'cell suicide'.
What is the difference between necrosis and infarction?
Necrosis means that a cell or a group of cells die due to injury (heat, pressure etc), diseases (infections), or other pathological state. The term "infarction" essentially is synonymous with "ischemic necrosis" which means necrosis (cell death) from the lack of blood (ischemia). Ischemia can be caused by the occlusion of the arterial supply or venous drainage for a particular tissue.
What is the difference between coagulative and liquefactive necrosis?
Liquefactive necrosis is good for your body, especially your brain (due to the beneficial liquids produced) but coagulative necrosis is bad due to the clumping and coagulation (i.e. clotting) that occurs.Coagulation necrosis is the "acute" necrosis in which the protein fibers become denatured and everything turns into a semi-solid mess of dead tissue. Liquefactive necrosis is a more "chronic" necrosis in which the dead tissue is digested into a liquid which can then be removed by the macrophages.
