Hormones are chemicals released by cells that affect cells in other areas of the body. Only a small amount of a hormone is required to alter cell metabolism. hormones are chemical messenger that transports a signal from one cell to another. All multicellular organisms produce hormones; plant hormones are also called phytohormones. Hormones in animals are often transported in the blood. Cells respond to a hormone when they express a specific receptor for that hormone. The hormone binds to the receptor protein, resulting in the activation of a signal transduction mechanism that ultimately leads to cell type-specific responses.
Hormones carry messages from glands to cells to maintain chemical levels in the bloodstream that achieve homeostasis. "Hormone" comes from a word that means, "to spur on." This reflects how the presence of hormones acts as a catalyst for other chemical changes at the cellular level necessary for growth, development, and energy.

As members of the endocrine system, glands manufacture hormones. Hormones circulate freely in the bloodstream, waiting to be recognized by a target cell, their intended destination. The target cell has a receptor that can only be activated by a specific type of hormone. Once activated, the cell knows to start a certain function within its walls. Genes might get activated, or energy production resumed. As special categories, autocrine hormones act on the cells of the secreting gland, while paracrine hormones act on nearby, but unrelated, cells.
There are two types of hormones known as steroids and peptides. In general, steroids are sex hormones related to sexual maturation and fertility. Steroids are made from cholesterol either by the placenta when we're in the womb, or by our adrenal gland or gonads (testes or ovaries) after birth. Cortisol, an example of a steroid hormone, breaks down damaged tissue so it can be replaced. Steroids determine physical development from puberty on to old age, as well as fertility cycles. If we are not synthesizing the correct steroidal hormones, we can sometimes supplement them pharmaceutically as with estrogen and progesterone.
Peptides regulate other functions such as sleep and sugar concentration. They are made from long strings of amino acids, so sometimes they are referred to as "protein" hormones. Growth hormone, for example, helps us burn fat and build up muscles. Another peptide hormone, insulin, starts the process to convert sugar into cellular energy.
Hormones so perfectly and efficiently manage homeostasis due to negative feedback cycles. Our goal is to keep the concentration of a certain chemical, such as testosterone, at a constant level for a certain period of time, the way that a thermostat works. Using negative feedback, a change in conditions causes a response that returns the conditions to their original state. When a room's temperature drops, the thermostat responds by turning the heat on. The room returns to the ideal temperature, and the heater turns off, keeping the conditions relatively constant.
Endocrine hormone molecules are secreted (released) directly into the bloodstream, while exocrine hormones (or ectohormones) are secreted directly into a duct, and from the duct they either flow into the bloodstream or they flow from cell to cell by diffusion in a process known as paracrine signalling. Hormones work as your body's chemical messengers. They travel in your bloodstream to tissues or organs. They work slowly, over time, and affect many different processes, including:
Endocrine glands, which are special groups of cells, make hormones. The major endocrine glands are the pituitary, pineal, thymus, thyroid, adrenal glands and pancreas. In addition, men produce hormones in their testes and women produce them in their ovaries.
Hormones are powerful. It takes only a tiny amount to cause big changes in cells or even your whole body. That is why too much or too little of a certain hormone can be serious. Laboratory tests can measure the hormone levels in your blood, urine or saliva. Your health care provider may perform these tests if you have symptoms of a hormone disorder. Home pregnancy tests are similar - they test for pregnancy hormones in your urine.
ANTI-AGING EXPERTS AND HORMONE REPLACEMENT THERAPY
Parathyroid Hormone (PTH) is a peptide hormone produced by the parathyroid glands. It binds to receptors in the bone and kidney. A decrease in serum calcium concentration and an increase in serum phosphorous concentration stimulate PTH secretion. PTH also:
- stimulates osteoclastic bone resorption indirectly to release calcium from bone.
- stimulates bone formation that is coupled to bone resorption.
- increases renal tubular reabsorption of calcium.
- stimulates the renal production of 1,25 dihydroxyvitamin D to increase calcium absorption from the intestine.
- enhances renal phosphate and bicarbonate excretion.
Calcitonin is ade hormone produced by cells within the thyroid gland. Calcitonin secretion is stimulated by high blood calcium concentrations, and it acts as a physiologic antagonist to PTH. Osteoclasts have receptors for calcitonin, but the effects are transient. Calcitonin also:
- inhibits osteoclast resorption
- delays calcium absorption from the intestine
- increases calcium urinary excretion
Dihydroxyvitamin D -
1,25 dihydroxyvitamin D is an active hormone which is produced by the kidney, under the control of PTH, from precursors of dietary vitamin D intake and UV skin-production of vitamin D. It is not really a vitamin, but the name was given many years ago, before anybody knew the function of this molecule. Vitamin D receptors are present in bone, kidney, intestines, and other cells. The chemical name is 1,25-dihydroxy-cholecalciferol, and it:
- promotes gastrointestinal absorption of calcium and phosphorus.
- is necessary for bone mineralization.
- stimulates bone resorption when given in high doses.
Gonadal steroid Hormones
Gonadal steroids are produced by the ovaries and testes and are very important in maintaining bone balance. They are also important in normal growth and development and in the development of peak bone mass. The mechanism of action is unclear but receptors for estrogen and androgen are found in bone.
- are the principal circulating sex steroids in females.
- are also necessary for bone strength in males.
- help regulate the rates of bone formation and bone resorption.
- decrease after menopause, contributing to development of osteoporosis.
Androgens (such as testosterone):
- are necessary for bone strength in males.
- decrease with aging, at a rate of 10% - 14% in males after the age of 25
- may increase bone formation in females.
Human Growth Hormone HGH
Human Growth Hormone is the largest protein produced by the pituitary gland made up of 191 amino acids. Proteins are made of building blocks known as amino acids. HGH - Growth hormone is produced by the pituitary gland, a pea-sized structure at the base of the brain — to fuel childhood growth and help maintain tissues and organs throughout life. Beginning in middle age 35 - 40 yrs of age, the pituitary gland slowly reduces the amount of growth hormone it produces and we beging to experience the effects of the aging.
Thyroid hormone is produced by the thyroid gland. Bone cells have receptors for thyroid. This hormone also:
- is necessary for growth and maturation of the skeleton.
- causes increased osteoclastic bone resorption and osteoporosis when levels are too high.
