2. Causes of hyper- Additional work by the tissue
trophy Excessive hormonal stimulation
3. Examples of hy- Enlarged heart resulting from increased demands
pertrophy Effect of consistent exercise on skeletal muscle, leading to an enlarged muscle
mass
4. Atrophy Decrease in cell size - results in reduced tissue mass
5. Causes of atro- Reduced use of the tissue

during pregnan-
cy
10. Metaplasia Mature cell type that is replaced by a different mature cell type
Adaptive mechanism that provides more resistance tissue

12. Dysplasia Abnormal growth or development of a tissue or organ
Cells vary in size and shape within a tissue
Large nuclei are frequently present
Rate of mitosis is increased
13. Causes of dyspla- Chronic irritation
sia Infection
Precancerous change
14. Neoplasia "New growth" or tumor
15. Ischemia Deficient of oxygen in the cells
16. Most common Ischemia
