Class 6 Flashcards
atrophy
decrease in cell size
Hypertrophy
cells (specifically muscle cells) become larger in response to work load
Hyperplasia
increased number of cells
metaplasia
one type of organized cell transforms into another type of organized cell in response to a stressor
is metaplasia reversible or irreversible?
reversible in certain cases if stressor is removed
dysplasia
changes in the size, shape, organization and appearance of cells into a more simple and immature cell. Often a precursor to malignancy (last reversible stage)
neoplasia
New growth (tumour)
benign neoplasias often end in?
“oma”
Malignant neoplasia often ends in?
“sarcoma” or “carcinoma”
lymphoma and melanoma are?
malignant
anaplasia
lack of differentiation
sustained proliferation
continuous cell growth signalling, mutations also promote growth
most common and earliest manifestation of cancer
fatigue and sleep disturbances
anemia
a decrease of hemoglobin in the blood
cachexia
severe weight loss and wasting of body fat and muscle tissue
