Pathophysiology (or physiopathology) is a branch of study, at the intersection of pathology and physiology, concerning disordered physiological processes that cause, result from, or are otherwise associated with a disease or injury.
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).
Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. [5] Physiological state is the condition of normal function. In contrast, pathological state refers to abnormal conditions, including human diseases.
The crossover between molecular pathology and epidemiology is represented by a related field "molecular pathological epidemiology". [22] Molecular pathology is commonly used in diagnosis of cancer and infectious diseases.
Tooth wear is a physiological process and is commonly seen as a normal part of aging. Advanced and excessive wear and tooth surface loss can be defined as pathological in nature, requiring intervention by a dental practitioner. The pathological wear of the tooth surface can be caused by bruxism, which is
As such, though it is convenient to consider clear cut distinctions between pathologic and physiologic cardiac hypertrophy, there may be a broader range of phenotypes than may be accounted for by gross cardiac phenotypes alone. [citation needed] The development of pathologic states in LVH is complex.
Angiogenesis is the most common type of neovascularization seen in development and growth, and is important to both physiological and pathological processes. [3] Angiogenesis occurs through the formation of new vessels from pre-existing vessels.
Anatomic pathology relates to the processing, examination, and diagnosis of surgical specimens by a physician trained in pathological diagnosis. Clinical pathology involves the laboratory analysis of tissue samples and bodily fluids; procedures may include blood sample analysis, urinalysis, stool sample analysis, and analysis of spinal fluid ...
