The Pitutitary Gland

The Pituitary Gland is located at the base of the brain. It is the most important gland of the endocrine system, because it controls the functions of the other endocrine glands. The endocrine glands secrete all the important hormones which control the functions of all the body organs.

Human Growth Hormone or HGH, the most important hormone, is secreted by the Pituitary Gland. It is the primary hormone responsible for functions of the brain, enzyme production, tissue repair and healing, reproduction and replacement of cells, control metabolism thus maintaining physical and mental health.
You can naturally stimulate your own pituitary gland to produce more HGH by exercise, careful attention to diet, and reducing body weight to optimum levels.

PCOS (Polycystic Ovary Disorder) is a variable disorder that is marked especially by amenorrhea, hirsutism, obesity, infertility, and ovarian enlargement and is usually initiated by an elevated level of luteinizing hormone, androgen, or estrogen which results in an abnormal cycle of gonadotropin release by the pituitary gland — abbreviation PCOS called also polycystic ovarian disease polycystic ovarian syndrome polycystic ovary disease Stein-Leventhal syndrome


Anatomy of the pituitary gland:

The pituitary gland is sometimes called the "master" gland of the endocrine system, because it controls the functions of the other endocrine glands. The pituitary gland is no larger than a pea, and is located at the base of the brain. The gland is attached to the hypothalamus (a part of the brain that affects the pituitary gland) by nerve fibers. The pituitary gland itself consists of three sections:

* the anterior lobe
* the intermediate lobe
* the posterior lobe

Functions of the pituitary gland:

Each lobe of the pituitary gland produces certain hormones.

anterior lobe:

* growth hormone
* prolactin - to stimulate milk production after giving birth
* ACTH (adrenocorticotropic hormone) - to stimulate the adrenal glands
* TSH (thyroid-stimulating hormone) - to stimulate the thyroid gland
* FSH (follicle-stimulating hormone) - to stimulate the ovaries and testes
* LH (luteinizing hormone) - to stimulate the ovaries or testes

intermediate lobe:

* melanocyte-stimulating hormone - to control skin pigmentation

posterior lobe:

* ADH (antidiuretic hormone) - to increase absorption of water into the blood
by the kidneys
* oxytocin - to contract the uterus during childbirth and stimulate milk production
