3 Questions
Which type of tissue can only undergo hypertrophy and not hyperplasia?
Cardiac muscle
What is the difference between hypertrophy and hyperplasia?
Hypertrophy involves gene activation, while hyperplasia does not
What is the risk associated with pathologic hyperplasia?
It can lead to dysplasia and eventually cancer
Study Notes
Tissue Types and Cellular Responses
- Muscular tissue (skeletal and smooth) and cardiac muscle tissue can only undergo hypertrophy, not hyperplasia.
Hypertrophy vs Hyperplasia
- Hypertrophy is an increase in the size of existing cells, resulting in an overall increase in tissue size.
- Hyperplasia is an increase in the number of cells, also resulting in an overall increase in tissue size.
Pathologic Hyperplasia Risks
- Pathologic hyperplasia is associated with an increased risk of cancer, as it can lead to uncontrolled cell growth and tumor formation.
Test your knowledge on the fascinating biological processes of hyperplasia and hypertrophy with this informative quiz. Learn about the different ways in which cells can increase in size and number in response to stress and understand the importance of gene activation, protein synthesis, and stem cell production. Discover how hyperplasia and hypertrophy work together to increase organ size and function. Take the quiz now and become an expert on these key concepts in biology.
