Module 2 - Unit 2 - Chapter 3 Cellular Adaptation, Injury, and Death Flashcards
Hyperplasia:
increase in number of cells; think mitosis
Metaplasia
replacement of adult cells - think change in cells d/t a stimulus
Dysplasia:
initial deranged cellular growth of a specific tissue without initial insult - think dysfunctional initial growth
Atrophy:
decrease in cell size
Hypertrophy
increase in cell size
Lactation hyperplasia
during pregnancy women will experience a hormonal driven increase in breast size.
Endometrial hyperplasia
increasing thickness of the endometrium (the lining of the uterus).
Caused by excessive estrogen. (Not a cancer but may lead to cancer).
Focal epithelial hyperplasia (also known as Heck’s disease)
A wart-like growth in the mucous tissues of the mouth
Caused by HPV
Airway metaplasia
cigarette smoke
Bladder metaplasia
bladder stones
Myelodysplastic syndrome:
Cancers in which immature blood cells in the bone marrow do not mature and therefore do not become healthy blood cells
Fibrous dysplasia of bone:
where normal bone and marrow is replaced with fibrous tissue, resulting in formation of bone that is weak and prone to expansion
Autophagy
“self - eat” meaning removal of damaged organelles within the cell common in atrophy
Heterophagy
“different - eat” eat and digest substances phagocytose from the external environment - common is when cells eat neutrophils and macrophages
Pathologic calcifications
abn disposition of calcium salts with other small amounts of iron, magnesium, and other mineral salts
