Basic Histology Flashcards
Formalin is best fixative for
Nervous Tissue
Organ/ tissue smaller than normal ; change happen at the start
Retrogressive changes
Incomplete/defective development of tissue/organ
Aplasia
non-appearance of an organ; failure of an organ to developed
Agnesia
failure of an organ to reach its full mature size
Hypoplasia
failure of an organ to form an opening
Atresia
Decrease in cell size of the normally mature/tissue/organ
Atrophy
wasting or shrinkage of tissues, particularly muscles, due to inactivity or reduced mechanical load.
Atrophy of Disuse
refers to the shrinking or degeneration of tissues or organs due to prolonged stress, overuse, or chronic stimulation, leading to cellular exhaustion and metabolic dysfunction
Exhaustion atrophy
refers to the shrinking or degeneration of tissues or organs due to prolonged stress, overuse, or chronic stimulation, leading to cellular exhaustion and metabolic dysfunction
Exhaustion atrophy
Tissue size increase bec size of individual cell; uterus during pregnancy
Hypertrophy
tissue size increase bec of INCREASE NUMBER of cells; there is CELL DIVISION/REPLICATION
Hyperplasia
reversible change involving transformation in one type of adult cell to another; chronic smoker
Metaplasia
reversible change involving transformation in one type of adult cell to another; chronic smoker
Metaplasia
a pathological condition characterized by abnormal growth and differentiation of cells within a tissue. It often represents a precancerous change; can go back to normal if the cause (like smoking or infection) is removed, but if ignored, it might turn into cancer.
Dysplasia
