PITUITARY GLAND |

The pituitary gland is part of the endocrine system which consists of glands situated in different areas of the body. Each gland in this system produces different hormones which regulate the activity of other organs and tissues in the body. These hormones are released directly into the blood flowing through the gland, in contrast to exocrine glands, which release hormones down a tube or duct. The science concerned with the structure and functions of the endocrine glands and the diagnosis and treatment of disorders of the endocrine system is called endocrinology.
The pituitary gland is located at the base of the brain in a pocket inside the sphenoid bone known as the sella tursica. It weighs only 1/2 gram (.018 ounces) of which 85% is water and it produces 1/100,000th of a gram of hormones daily. The pituitary gland via hormone secretion directly affects the thyroid, adrenals, ovaries, testes, kidneys, breasts. According to An Endocrine Interpretation of Chapman’s Reflexes: the pituitary "also exerts a definite influence on the intestines, bladder, uterus, stomach, and spleen, its actions causing contraction of the plain, unstriped muscles of the entire body" (page 13).
PITUITARY HORMONES Pituitary secretions are in most part in response to signals from the hypothalamus. It communicates with the posterior pituitary via nerve fibers and the anterior pituitary via minute capillaries. The hypothalamus collects information from the body concerning hormone and electrolyte levels, pain, emotions, etc., and signals the pituitary accordingly with the optimum health of the body in mind.
There are seven major hormones secreted by the anterior pituitary: growth hormone (GH), adrenal corticotrophic hormone (ACTH), thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), luteinizing hormone (LH), melanocyte stimulating hormone (MSH), and prolactin. GH or human growth hormone (HGH) promotes an increase in the size and number of all cells in the body capable of growth and reproduction. It stimulates protein synthesis and muscle growth while stimulating the body to use up fat stores. It increases blood sugar levels (thus stimulating insulin production) by decreasing carbohydrate utilization. It also stimulates the production of a substance that promotes proper bone and cartilage growth, development, and repair. Growth hormone is also necessary for tissue repair, and plays a role in increasing our resistance to disease by stimulating the immune system. It can speed wound healing, decrease blood urea levels, and prevent or reverse osteoporosis. It is released in response to sleep, fasting, and exercise. Many people over 50 no longer produce any GH. ACTH stimulates cortisol secretion by the adrenal glands and can increase its secretion up to 2000%. It also has a small effect on aldosterone and perhaps estrogen secretion. ACTH can be stimulated by low blood sugar, infection, surgery, chronic disease, norepinephrine and similar medications, intense heat or cold. TSH signals the thyroid to secrete thyroxine and triiodothyronine. It also increases the production of these hormones and increases the size and number of thyroid cells. Two factors that cause abnormally high TSH secretion are intense cold and emotional trauma. FSH in males aids in formation of sperm and in females aids in the development of the egg and production of estrogen (see chapter on ovaries for more information). LH in males stimulates the formation of testosterone and in females it is necessary for follicular growth, ovulation and progesterone and estrogen production (see ovary chapter for more details). MSH controls darkening of the skin and possibly plays a role in retention of visual stimulation and memory. Prolactin aids in breast development during pregnancy, stimulates the mammary gland cells to synthesize fat, lactose, and casein, thus producing milk. Prolactin formation is normally inhibited until pregnancy and it reaches a maximum after giving birth.
The posterior pituitary secretes oxytocin and antidiuretic hormone (ADH). Oxytocin is actually produced by the hypothalamus but stored in the posterior pituitary. It stimulates the pregnant uterus to begin the onset of labor, and also causes milk to travel from the alveoli to the ducts making it available for the nursing child. ADH is also produced in the hypothalamus and stored in the posterior pituitary. It controls the permeability of the renal tubules. Secretion of ADH causes the kidneys to conserve water and electrolytes. ADH is usually excreted in high volumes during periods of blood loss.

The Pituitary Gland, HGH and Anti-AgingScientific medical research has discovered incredible new links to the disease we all suffer from. This disease is known as aging or growing old. We all know that maturing through the years is a reality that must be faced, but it is also a widely accepted fact that our bodies were designed to function and live at optimum health for 120 to 130 years. So why is this not happening for the majority of the population of the world? The answer is body balance. Because of changes occurring all around the world that are effecting our environment, our fluid consumption, our food intake, and most of all, the introduction of new and harsh toxins that our bodies are being subjected to every day, we cannot maintain this state of balance. However, through natural supplementation it has been found that the body can be nourished with the nutrients it needs so that it can return itself to a state of balance. In the past, this was achieved by a process involving a regimen of preventative measures. THEN…. the scientific basis of a new and incredible find involved the natural stimulation of the master gland of our hormonal system known as the pituitary gland. Medical case studies involving over 10,000 participants showed impressive results when a mixture of natural nutrients traditionally known to stimulate the pituitary gland and its production of human growth hormone (HGH) were administered. In his book "Grow Young With HGH", Dr. Ronald Klatz quotes a New England Journal of Medicine study showing that HGH produced naturally by our pituitary increases until about age 21, then declines with age. At age 70, our HGH level, as measured in blood tests, is only 20% of that at age 21. Building on these studies, research scientists discovered that when increasing the levels of HGH in the body, the conditions associated with the aging process actually began to reverse over a period of 3 to 6 months. These results were originally produced using a synthetic mixture that was administered hypodermically. The results were spectacular, but the cost and side effects to the synthetic hormone were also staggering. HERE …. are actual findings from the studies. BODY FLUCTUATION Improvement
SKIN AND HAIR Improvement
HEALING, FLEXIBILITY AND RESISTANCE Improvement
SEXUAL FUNCTION Improvement
ENERGY, EMOTIONS AND MEMORY Improvement
These improvements were reported to occur within 1 to 3 months with a tendency to continue improving over a 6 month timeframe. For further confirmation, read Dr. Klatz’s book. Dr. Klatz is President of the American Academy of Anti-aging Medicine. Or review the New England Journal of Medicine. Studies have been documented in several medical journals around the world with respect to HGH. In the near future, HGH will be front cover news for many popular magazines and journals. NOW….
The world renown research team at Unicity developed Enjuvenate™,
as a safe response to the demand to slow and even reverse the effects of
aging for men and women, isolated the nutritional ingredients that are
necessary to naturally and safely stimulate the pituitary gland so that the
body can increase its own production of HGH without negative side effects.
The methodolgy used is amino acid precursors. Enjuvenate™ naturally helps to
restore levels of HGH that decline significantly as we age. The Enjuvenate™
formula is the highest quality of any product in its category. Diabetics
should modify
recommended use. PLEASE…. do yourself a favour and investigate HGH. It’s now within your power to add quality to your life by rolling back the aging process. We believe HGH also has the power to extend our journey.
Experience
VIAGRA-LIKE benefits. Enjuvenate™ contains ideal
amounts of tribulus terrestris (puncture vine), a plant used by naturopaths
and homeopaths to improve sexual health for men and
women and to help impotency. The natural formulation of Enjuvenate has become a number one selling product for Unicity, one of the largest nutritional company in the world promoting the health of individuals through natural supplementation and herbal products.
