Patho NR283-Exam 1 Study Guide Chapter 1 Atrophy: ▪ Decrease in the size of cells ▪ Results in reduced tissue mass ▪ Common causes: reduced use of the tissue (in cast), insufficient nutrition, decrease neurologic or hormonal stimulation, aging Hypertrophy: ▪ Increase in cell size ▪ Results in enlarged tissue mass; ex) enlarged heart w/ heart failure ▪ Causes: additional work by the tissue( lifting weights), excessive hormonal stimulation Hyperplasia: ▪ Increased nu...

NR 283 Pathophysiology Exam 1 Concepts to Review Cellular Biology/Cellular Adaptation/Cellular Injury Chapter 1 o Cellular Adaptation o Atrophy – decrease in size of cells, resulting in reduced tissue mass (immobilized limb in a cast) o Hypertrophy – increase in size of cells, resulting in an enlarged tissue mass (enlarged heart muscle) o Hyperplasia – increase in number of cells, resulting in enlarged tissue mass (could be compensatory mechanism or hormonal imbalance, cancer)...
