1 The phenotype may change constantly throughout the life of an individual because of environmental changes and the physiological and morphological changes associated with aging.
One special group of hormones is the tropic hormones that stimulate the hormone production of other endocrine glands. For example, thyroid-stimulating hormone (TSH) causes growth and increased activity of another endocrine gland, the thyroid, which increases output of thyroid hormones. hormone (from Greek á½ÏÎ¼Î®, impetus) is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.
Production of Blood Sugar. In the case of blood sugar, a hormone stimulates the liver as well as the kidneys. The sugar that fuels many of the body's processes exists as glucose. The liver stores excess glucose and also synthesizes new glucose if the body's supply is low.Researchers have determined that the kidneys can synthesize glucose as well. The kidneys and the liver are stimulated to do this by low levels of the hormone insulin.roduction of Blood Sugar. In the case of blood sugar, a hormone stimulates the liver as well as the kidneys.
