It is only pea-sized and weighs less than a gram. Nevertheless, it controls the entire human hormone system. If they get out of joint, it can lead to many diseases.
Two cloths with different functions
Like a drop, the pituitary gland, also referred to as the pituitary gland, attaches to the hypothalamus, an area of the brain. There it lies in a bony depression just above the base of the skull, the so-called Turkish saddle. It consists of two halves, the posterior pituitary and the anterior pituitary, which operate independently of each other.
The pituitary backbone is a storage organ. The hormones adiuretin (formerly called vasopressin) and oxytocin, which are formed in the hypothalamus, are stored there and released when needed. Adiuretine plays an important role in regulating the water balance of the body. Oxytocin triggers labor during pregnancy, and during breastfeeding ensures that breast milk is injected.
In the anterior pituitary a variety of hormones are formed. The superordinate hypothalamus releases "control hormones", which stimulate the pituitary gland to produce its own messengers, or inhibit its formation. In the pituitary gland, among other things, hormones are produced that affect the thyroid and adrenal glands, have an influence on the pigmentation of the skin and are responsible for the formation of estrogen, the maturation of the ovaries and the development of sperm.

Human hormone and nervous system are very complex and closely related.
