Which of the following is not a consequence of cellular events in atherosclerotic infarction_____________?
Show answer Hide answer
Answer: B. Astrocytes
Explanation
Astrocytes are specialized glial cells located within the central nervous system supporting neuronal function and tissue homeostasis. These cells participate in glial scarring within the brain and are not involved in atherosclerotic cardiovascular infarctions. Cardiovascular infarctions involve inflammatory cells and myocardial tissue rather than central nervous system glial elements. Atherosclerosis involves plaque buildup inside arterial walls that can rupture and cause localized ischemic tissue infarction. Cellular events following infarction include acute neutrophilic infiltration followed by macrophage clearance of necrotic debris. Intense eosinophilia often characterizes necrotic myocytes observed under microscopic examination following a myocardial infarction.
Neutrophilic infiltration is an expected early cellular event following acute ischemic tissue infarction injuries. Ingress of macrophages occurs shortly after neutrophil influx to phagocytose necrotic cellular debris in infarctions. Intense eosinophilia of necrotic cells is a classic histological feature observed in early myocardial tissue infarctions.
