1. Definition:
Atrophy refers to the decrease in the size of a body part, cell, organ, or other tissue while hypertrophy refers to the enlargement of an organ or tissue from the increase in the size of its cells.
2. Cause:
Moreover, atrophy occurs when organs or tissues are not used at all while hypertrophy occurs due to excess work.
3. Results in:
While atrophy results in a decrease in the size of the organ, hypertrophy results in an increase in the size of the organ.
4. Physiological Importance:
Senile atrophy, the atrophy in the thymus after puberty, and atrophy in ovaries and breasts during menopause are the physiological conditions of atrophy while the muscles of bodybuilders and the uterus in pregnant mothers are the physiological conditions of hypertrophy.
5. Pathological Importance
Chronic malnutrition and other chronic diseases cause atrophy, while hypertrophy can be either adaptive or compensatory.
6. Conclusion
Atrophy is the condition of decreasing the size of an organ or tissue when they are not used for a long time. Further, malnutrition, chronic diseases, and aging are the causes of atrophy. On the other hand, hypertrophy is the condition of increasing the size of an organ or tissue due to excess work. Generally, this is by increasing cell volume. As an example, muscle hypertrophy occurs in bodybuilders. Therefore, the main difference between atrophy and hypertrophy is the type of change in organs and tissues and its causes.
1. Definition of Hypertrophy and Hyperplasia: Hypertrophy: Hypertrophy is an increase in the volume of a given tissue or organ due only to the enlargement of the cells. Hyperplasia: Hyperplasia is an increase in the amount of tissue, resulting from cell proliferation. 2. Genesis of Hypertrophy and HRead more
1. Definition of Hypertrophy and Hyperplasia:
Hypertrophy: Hypertrophy is an increase in the volume of a given tissue or organ due only to the enlargement of the cells.
Hyperplasia: Hyperplasia is an increase in the amount of tissue, resulting from cell proliferation.
2. Genesis of Hypertrophy and Hyperplasia:
Hypertrophy: Hypertrophy is mainly provoked by increased demand.
Hyperplasia: Hyperplasia is mainly provoked by excessive cell stimulation.
3. Process of Hypertrophy and Hyperplasia:
Hypertrophy: Hypertrophy is a result of cell enlargement.
Hyperplasia: Hyperplasia is a result of cell proliferation.
4. Mechanism of Hypertrophy and Hyperplasia:
Hypertrophy: Hypertrophy is a result of increased protein production in the cells.
Hyperplasia: Hyperplasia is a result of the proliferation of mature cells, driven by growth factors.
5. Affected cells of Hypertrophy and Hyperplasia:
See lessHypertrophy: Hypertrophy occurs in permanent cells (non-dividing, such as skeletal muscle, cardiac muscle, etc.).
Hyperplasia: Hyperplasia occurs in labile or stable dividing cells.
