The pituitary, a pea-sized gland at the base of the brain, produces a number of hormones. Each of these hormones affects a specific part of the body (a target organ or tissue). Because the pituitary controls the function of most other endocrine glands, it is often called the master gland.
function of pituitary gland
It secretes a variety of hormones into the bloodstream which act as messengers to transmit information from the pituitary gland to distant cells, regulating their activity. For example, the pituitary gland produces prolactin, which acts on the mammary glands in the breasts to induce milk production. The pituitary gland also secretes hormones that act on the adrenal glands, thyroid gland, ovaries and testes, which in turn produce other hormones. Through secretion of its hormones, the pituitary gland controls metabolism, growth, sexual maturation, reproduction, blood pressure and many other vital physical functions and processes.
the anterior pituitary gland produces the following hormones and releases them into the bloodstream:
Adrenocorticotropic hormone, which stimulates the adrenal glands to secrete steroid hormones, principally cortisol
Growth hormone, which regulates growth, metabolism and body composition via acting on the liver, bones, adipose tissue (fat deposit) and muscle
Luteinising hormone and follicle stimulating hormone, also known as gonadotrophins. They act on the ovaries or testes to stimulate sex hormone production, and egg and sperm maturity
Prolactin, which stimulates milk production in the mammary glands
Thyroid stimulating hormone, which stimulates the thyroid gland to secrete thyroid hormones.
Each of these hormones is made by a separate type of cell within the pituitary gland, except for follicle stimulating hormone and luteinising hormone, which are made together by the same cell.
Two hormones are produced by the hypothalamus and then stored in the posterior pituitary gland before being secreted into the bloodstream. These are:
Anti-diuretic hormone (also called vasopressin), which controls water balance and blood pressure
Oxytocin, which stimulates uterine contractions during labour and milk secretion during breastfeeding.
Between the anterior pituitary and the posterior pituitary lies the pars intermedia, also called intermediate pituitary gland. Cells here produce:
Melanocyte-stimulating hormone, which acts on cells in the skin to stimulate the production of melanin, which is a pigment that protects against ultraviolet (UV) radiation
