Nontumor‐associated increase in tissue or organ size related to an increase in constituent cell size. A hypertrophic response may occur as a result of a particular condition. To be distinguished from hyperplasia, which is related to an increase in cell number.
Enlargement or overgrowth of an organ.
A term used to describe an increase in the size, girth, or function of muscle tissue.
Increase in size of tissue, organ, or cell, independent of general body growth.
Abnormal increase in size of an organ (cell numbers remain constant).
Increase in size or volume of an organ or other body structure that is produced entirely by an increase in the size of existing cells, not by an increase in the number of cells.
Enlargement of an organ or structure.
An enlargement or overgrowth of an organ or tissue.
An enlargement or outgrowth of a bodily part or organ because of enlargement of its constituent elements.
An increase in the number or size of cells in a tissue.
Increase in the size of an organ or other part, resulting from enlargement of the individual cells (compare atrophy; hyperplasia).
Enlargement or overgrowth of a body part or organ due to an increase in the size of its cells. Organs such as the heart, liver, and muscles are prone to hypertrophy, a condition that can cause medical problems. Treatment is aimed at the underlying cause.
Increase in the size of a tissue or organ brought about by the enlargement of its cells rather than by cell multiplication (as during normal growth and tumor formation). Muscles undergo this change in response to increased work.
The increase in size which takes place in an organ as the result of an increased amount of work demanded of it by the bodily economy. For example, when valvular disease of the heart is present, compensation occurs by an increase in thickness of the heart muscle, and the organ, by beating more powerfully, is able to overcome the strain thrown upon it. Similarly, if one kidney is removed, the other hypertrophies or grows larger to take over the double workload.
An increase in the size of an organ or structure, or of the body owing to growth rather than tumor formation. This term generally is restricted to an increase in size or bulk that results not from an increase in number of cells, but rather from an increase in cellular components, such as proteins. It sometimes is used to apply to any increase in size as a result of functional activity.
Hypertrophy is an increase in muscle size due to enlargement of existing muscle fibers. Muscles exhibit hypertrophy when exercised.
This condition refers to the abnormal and extreme increase in size resulting from the expansion of individual cells, such as those found in the root deformities of Cruciferae plants. This enlargement occurs in conjunction with hyperplasia and is triggered by the infection of the plant with Plasmodiophora brassicae.
Hypertrophy refers to the expansion of an organ or tissue, a result of the growth in size, not the quantity, of its individual cells. For instance, skeletal muscles may grow larger due to heightened physical demands.
A growth in the size of a tissue or organ resulting from the expansion of its individual cells.
