Questions and Answers
Which type of tissue can only undergo hypertrophy and not hyperplasia?
Which type of tissue can only undergo hypertrophy and not hyperplasia?
- Nerve
- Endometrial tissue
- Cardiac muscle (correct)
- Skeletal muscle
What is the difference between hypertrophy and hyperplasia?
What is the difference between hypertrophy and hyperplasia?
- Hypertrophy only occurs in permanent tissues, while hyperplasia occurs in all tissues
- Hypertrophy and hyperplasia are the same thing
- Hypertrophy involves gene activation, while hyperplasia does not (correct)
- Hypertrophy involves an increase in cell number, while hyperplasia involves an increase in cell size
What is the risk associated with pathologic hyperplasia?
What is the risk associated with pathologic hyperplasia?
- It can lead to organ failure
- It can cause systemic hypertension
- It can cause benign prostatic hyperplasia
- It can lead to dysplasia and eventually cancer (correct)
Flashcards
Hypertrophy
Hypertrophy
Increase in cell size without an increase in cell number. Can only occur in tissues whose cells cannot divide, such as cardiac muscle.
Hyperplasia
Hyperplasia
Increase in cell number due to cell division. Can occur in tissues whose cells are capable of dividing.
Pathologic Hyperplasia Risk
Pathologic Hyperplasia Risk
Can progress to dysplasia, which is disordered cell growth, and eventually to 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.
