Final answer:
Ischemic necrosis is the medical term for localized tissue necrosis due to the cessation of blood supply. It occurs when there is a blockage or narrowing of blood vessels, leading to reduced blood flow to a specific area of tissue.
Step-by-step explanation:
The medical term for localized tissue necrosis due to the cessation of blood supply is ischemic necrosis. Ischemic necrosis occurs when there is a blockage or narrowing of blood vessels, leading to reduced blood flow to a specific area of tissue. This lack of blood supply causes the tissue to become deprived of oxygen and nutrients, resulting in tissue death.
For example, a common type of ischemic necrosis is a stroke. In a stroke, an artery in the brain becomes blocked, cutting off blood supply to a specific region of the brain. Without adequate blood flow, the brain tissue in that region becomes ischemic and eventually dies.
Ischemic necrosis can also occur in other parts of the body due to various factors, such as pressure on the skin leading to bedsores or a severe injury causing blood vessel severing. Prompt medical intervention is crucial to prevent further damage and promote healing.
