What is the difference between hypertrophy and hyperplasia

In secretory cells, the secretary system — including the endoplasmic reticulum , ribosomes , and the Golgi zone — become prominent. In contractile cells like muscle fibers, there is an increase in the size of myofibrils. Hypertrophy is due to increased demand. In physiological hypertrophy, when the demand is removed, the tissues return to normal overtime. Pathological hypertrophy is also due to increased demand. However, in pathological hypertrophy, tissues do not return to normal when the demand is removed.

Myocardial hypertrophy, if it occurs without a recognizable cause, is considered as an example of pathological hypertrophy. Such hypertrophy is frequently associated with abnormal cardiac function. Hypertrophy is due to increased demand while mostly hyperplasia is due to excessive cell stimulation. Your email address will not be published.

The difference between hypertrophy and hyperplasia are given below in a tabular column. Hyperplasia Vs Hypertrophy Hyperplasia Hypertrophy Increase in the amount of a tissue due to cell proliferation. Both can be shortened to BPH and the terms are of often used interchangeably by patients and clinicians alike. While both represent an increase in the size of the prostate, the two phrases do have slightly different meanings. Hyperplasia involves the growth in the number of prostatic cells.

Each individual cell remains roughly normal in size, but the sheer increase in the number of these cells causes the prostate to expand. The cardiovascular load increases with large physical loads which results in compensatory hypertrophy. Regenerative Hypertrophy. It happens when one part of an organ dies or gets removed.

This organ's remaining cells increase their volume and begin working more intensively to compensate for the loss. This is possible, for example, in kidney and liver diseases. Vicarious Hypertrophy. It develops on the loss of one of the two double organs. The remaining organ assumes the entire load and increases significantly.

This happens for example after removing one kidney. Vicarious hypertrophy occurs on the loss of one of the two double organs. The remaining organ absorbs all of the load and greatly increases. For example: This occurs after removal of the one kidney. Hyperplasia is termed when there is an increase in the amount of a tissue that results from cell proliferation.

It can lead to a considerable enlargement of a certain organ. A common response to a stimulus is the hyperplasia. The cells which have been obtained are normal but in increased numbers.
