This hormone is involved in the growth, cell reproduction and regenerative property of a cell. Hence, it helps in the total growth and development of the body of an individual. This hormone is found in large quantities among children than among adults. It has no role in targeting other endocrine glands as they help only in the process of growth and development. Hence, the given statement seems to be false.
