Detailed explanation-1: -Definition: Adaptations are reversible changes in the size, number, phenotype, metabolic activity, or functions of cells in response to changes in their environment. Type of Cellular Adaptation: Hyperplasia.
Detailed explanation-2: -Metaplasia is the reversible change of one differentiated cell type to another. It usually occurs in epithelial tissues as an adaptive response to cell stress; cells can be substituted by those types better suited to the environment.
Detailed explanation-3: -If cells cannot adapt to the pathologic stimulus, they can die. This chapter will discuss cellular adaptation, cell injury, cellular accumulations, and cellular aging. Overview: The four basic types of cellular adaptation to be discussed in this section are hyperplasia, hypertrophy, atrophy, and metaplasia.
Detailed explanation-4: -Five major types of adaptation include atrophy, hypertrophy, hyperplasia, dysplasia, and metaplasia.
Detailed explanation-5: -In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Four types of morphological adaptations include atrophy, hypertrophy, hyperplasia, and metaplasia.
