Which term describes atrophic change in tissues or cells?

The term that describes atrophic change in tissues or cells is "cataplasia." Cataplasia refers to the process where cells or tissues undergo degeneration or decrease in size, leading to a reduction in their functional capacity. This can result from various factors, including lack of nutrition, disuse, or disease processes. Understanding cataplasia is crucial in medical contexts, as it can indicate underlying health issues where tissues are not maintaining their normal function.

The other terms provided refer to different medical concepts. Bucnemia, while it may seem related, refers to an abnormal condition associated with the presence of too few red blood cells in a certain context, not atrophic change. Bronchopneumonia is a type of pneumonia that affects the lungs’ air sacs and is characterized by inflammation, rather than degeneration of tissue. Cholangioagraphy is a diagnostic imaging technique for visualizing the bile duct system, which does not pertain to tissue atrophy. Thus, cataplasia is the correct term when discussing atrophic changes in cells or tissues.
