Chapter 2, Altered Cellular and Tissue Biology

cell adaptation - correct answer when a cell adapts to escape and prevent injury physiologic or pathologic - correct answer What are the two categories that adapted cells fall in? physiologic - correct answer normal changes that everybody goes through, not negative or disease causing pathologic - correct answer associated with disease or undesired changes that might happen with age or decrease in stimulus atrophy - correct answer the type of cellular adaptation that is a decrease in cell size thymus atrophies as you develop - correct answer What is an example of physiologic atrophy? decrease in sexual hormones, decrease in muscles due to sickness, skeletal muscle decrease due to injury - correct answer What are examples of pathologic atrophy? hypertrophy - correct answer the type of cell adaptation that is the increase in cell size due to increase in proteins, not fluid accumulation increase in cardiac muscle due to hypertension, increase in kidney size after one kidney is removed - correct answer What are examples of pathologic hypertrophy? weight-bearing exercise, pregnancy - correct answer What are examples of physiologic hypertrophy? hyperplasia - correct answer the type of cellular adaptation when there is an increase in the number of cells due to mitosis, the cell cycle speeds up no - correct answer Is hyperplasia a cancer state? hypertrophy - correct answer What can hyperplasia co occur with? pregnancy, compensation or regeneration - correct answer What are some physiologic examples of hypertrophy? enlarged prostate due to increase in hormone levels, abnormal growth of endometrium in women - correct answer What are some pathologic examples of hypertrophy? dysplasia - correct answer Which of the cellular adaptation is not a true adaptation? dysplasia - correct answer the type of adaptation that is basically atypical hyperplasia, however there are abnormal changes in cell shape, size, and organization NO - correct answer Does dysplasia have any physiologic examples? cervix caused by HPV and respiratory tract due to smoking - correct answer Where in the human body is dysplasia common? metaplasia - correct answer the type of cellular adaptation where there is a reversible replacement of a mature cell by a less mature cell NO - correct answer Are there any physiologic examples of metaplasia? cellular injury - correct answer What can occur when a cell cannot maintain homeostasis? hypoxic injury - correct answer What is the most common cell injury? hypoxic injury - correct answer injury in the cell when the cell loses oxygen
