Hyperfunction

 

the intensification of the activity (function) of a given organ, tissue, or system. In some cases hyperfunction may be an adaptive reaction to living conditions. (For example, in athletes there may be an increase in the size—hypertrophy—of the cardiac muscle and increase in the strength of its contractions.) In other cases it is a disorder leading to illness of the organism. (For example, hyperthyroidism results from hyperfunction of the thyroid gland—increased production of the hormone thyroxine.)
