General Pathology: Cellular Adaptations Lorne Holland, M.D. Pathology, Lecture 2, Cell Injury (slides) by aal_qudsi in Types > School Work, pathology, and lecture 2 Alteration in cell morphology (structure and appearance) or cell function. Linda A. Dokas, in Methods in Neurosciences, 1994. 1–2). The main adaptations to a persistent stimulus may involve cellular hypertrophy, hyperplasia and metaplasia (see diagram # 6). Lorne.Holland@ucdenver.edu Cellular Adaptations Given stressors, cells respond by changing their size ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 4c05f3-MjI3Y Their technique allows the authors to define the intrinsic spatial and temporal sequence or “hierarchy” of molecular events involved in the dynamic behavior of a cellular superstructure—in this case, the leading edge—in the absence of the confounding compensatory mechanisms underlying cellular adaptation. 4 Cellular Injury is caused by exposure to.

Glucocorticoid hormones produce a spectrum of cellular adaptations in neurons, ranging from alterations in enzyme activity to ultrastructural and morphological changes, that are dependent on protein expression. Altered Cellular and Tissue Biology Chapter 3 Cellular Adaptation •Physiologic (normal) vs. pathogenic (diseased states) –Atrophy –Hypertrophy –Hyperplasia –Metaplasia –Dysplasia Cellular Adaptation Atrophy – decrease in cell size Hypertrophy – increase in cell size Hyperplasia – increase in cell numbers (incr.

Atrophy occurs whenever certain normal stimuli (workload, blood supply, etc) are decreased or lost. • Discriminate cell adaptation, reversible cell injury and irreversible cell injury (cell death) based on etiology, pathogenesis and histological and ultrastructural appearance. The major known signaling pathways and their functional effects are shown. Cell injury may be sublethal and result in a variety of types of cell degenerations or accumulations and/or adaptations by the cell to the injury. Metaplasia is irreversible.
