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.

What is the difference between hypoxia and ischemia?
simply, Hypoxia is less oxygen supply to cell tissues, while the Ischemia is less blood supply to cell issues.
How do you use ischemia in a sentence?
ischemia is a result of hypoxia. hypoxia means low oxygen in the heart.
How do you describe symptomatic ischemia?
Symptomatic ischemia is characterized by chest pain called angina pectoris.
What are the causes of silent ischemia?
Silent ischemia usually is caused by emotional or mental stress or by exertion, but there are no symptoms.
What is inferoapical ischemia?
Inferoapical ischemia is lack of blood flow below the apex.
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 reversible and irreversible ischemia?
what is reversible vs irreversible ischemia in the brain
Sudden tissue necrosis resulting from insufficient blood supply is?
Sudden necrosis caused by lack of blood flow is called ischemia. This happens in cases of injury, and can lead to gangrene.
What is the difference between hypoxia and ischemia?
simply, Hypoxia is less oxygen supply to cell tissues, while the Ischemia is less blood supply to cell issues.
What can cause necrosis and what does necrosis look like?
Necrosis can be caused by external or internal factors. External factors include blood vessels damage, mechanical trauma, and ischemia. Extremely high or low temperature can cause disruption of cells, which may result in necrosis. Internal factors like trophoneurotic disorder, pancreatic enzymes, injury and paralysis of nerve cells can also cause necrosis. Sometimes steroids can also cause necrosis.
What is the difference between ischaemia and infarction?
Ischemia=decreased oxygen/nutrients Infarction=no blood flow to the area ischemia can leads to infarction. ischemia means, reduced of blood supply to specific organ. while, infarction refers to death tissue.
ALT elevations?
significant...hepatitis, hepatic necrosis, hepatic ischemia, shock liver.....moderate elevation: cirrhosis, obstruction....mild: pancreatitis, mono, shock, drugs
Difference between myocardial ischemia and aortic dissection?
in myocadial ischemia, pain radiate to jaw, neck,shoulder,arm wheras in aortic dissection pain radiate to back, between scapulae there is differense between pulse rate of both arms and leg depending on ecg changes
What is the difference between apoptosis and necrosis?
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').
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.
What is the medical term meaning death of bone tissue due to insufficient blood supply?
Infarction is death of body tissue (also known as necrosis) due to insufficient blood or oxygen supply. Ischemia is a related term relating to the decrease in oxygen or blood supply. Gangrene is the condition resulting from bacterial invasion of an area of necrosis.
Deficient blood supply to the myocardium is?
Deficient blood supply to the myocardium is: ischemia Ischemia is the medical terms for deficient blood supply to the myocardium. The suffix -emia denotes a blood condition; ischem/o means to hold back. With occlusion from atherosclerosis, the blood flow is restricted, resulting in deficient blood supply.
