Growth hormone: This hormone is a protein. The growth hormone stimulates growth of all the body cells including the skeletal and muscular tissues. Under secretion of the growth hormone during the years of skeletal growth of an individual results in dwarfism, whereas an over secretion of the growth hormone prior to adulthood result in gigantism.
Thyroid hormone: The thyroid hormones stimulate the rate of oxygen consumption and resulting heat production of the various cells and tissues of the body. The metabolic action of the thyroid hormones is directly related to the regulation of the body temperature in mammals.
Follicle-Stimulating Hormone (FSH): It is so-called because it stimulates the development and maturation of the ovarian follicles producing the egg cell and one of the female sex hormones, estrogen. In the male the FSH induces spermatogenesis in the testes.
Luteinizing Hormone (LH): It is also responsible for stimulating the development of the corpus luteum that in turn secretes progesterone.
