What is Apoptosis? - A programmed cell death What is necrosis? - Death of most or all of the cells in an organ or tissue due to disease, injury, or failure of the blood supply. Characteristics of tissue necrosis - 1) Rapid loss of of the plasma membrane structure 2) Organelle swelling 3) Mitochondrial dysfunction Hypoxia - What is the #1 major cause of cellular injury leading to necrosis. (especially the kidney and heart) What is hypertrophy? - Is an increase in the size of cells Physi...

Hypertrophy Increase in cell size - results in enlarged tissue mass Causes of hypertrophy Additional work by the tissue Excessive hormonal stimulation Examples of hypertrophy Enlarged heart resulting from increased demands Effect of consistent exercise on skeletal muscle, leading to an enlarged muscle mass Atrophy Decrease in cell size - results in reduced tissue mass Causes of atrophy Reduced use of the tissue Insufficient nutrition Decreased neurologic or hormonal stimulatio...

Differences b/w dysplasia, hyperplasia, physiological (6 q) a. Dysplasia = deranged growth immature cells of a specific tissue that results in atypical cells (cells vary in size, shape, and appearance) i. often a precursor of cancer (ex. cervical dysplasia – cells start to change + become precancerous or cancerous) ii. * Google: Dysplasia refers to an abnormality in the maturation of cells within a tissue; consists of an increase in immature cells with a corresponding decrease in mature...
