- A hormone (from Greek ὁρμή, impetus) is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.ormone synthesis may occur in specific tissues of endocrine glands or in other specialized cells. Hormone synthesis occurs in response to specific biochemical signals induced by a wide range of regulatory systems.

What is the purpose of hormones? Hormones are a kind of biochemical messengers. Most hormones are chemical substances produced by specialized tissue formations called endocrine glands. The substances are secreted directly into the bloodstream, other body fluids, or into adjacent tissues.The purpose of hormones is to regulate metabolic activity of some other organs or tissues of the body.Three different ways hormones act: 1. Alter the rate of synthesis of your cellular protein. 2. Change the rate of enzyme activity. 3. Change the rate of transport of nutrients through the cell wall.he purpose of hormones is to regulate metabolic activity of some other organs or tissues of the body.

Growth hormone Growth hormone, also known as somatotropin, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. It is a type of mitogen which is specific only to certain kinds of cells. Growth hormone is a 191-amino acid, single-chain polypeptide that is synthesized, stored and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland. GH is a stress hormone that raises the con

Hormones Hormones are molecules released by a group of cells in the body that influence the behavior of another group of cells. Hormones are the chemical signals of the endocrine system, the group of glands that, along with the nervous system, controls the body's responses to internal and external stimuli. Hormones are carried to their target cells in the bloodstream. All hormones bind at the target cell to a specific receptor, a protein made by the target cell. When the hormone binds to the receptor, it causes a change in the receptor's conformation , or shape.

- Testosterone (androgen) is a hormone. Hormones are powerful chemicals that help keep our bodies working normally. The term hormone is derived from the Greek word, hormo, which means to set in motion.And that’s precisely what hormones do. They stimulate, regulate, and control the function of various tissues and organs.Made by specialized groups of cells within structures called glands, hormones are involved in almost every biological process, including sexual reproduction, growth, metabolism, and immune function.njected into a growth-stunted child, the child grew taller. At that time, growth hormone was extracted from the pituitaries of cadavers. As heat destroyed this pituitary extract, it could not be pasteurized and the problem of transmitting disease also existed. In 1986 the Eli Lilly and Company developed Humatrope.

- What is estrogen? Estrogens are a group of hormones that play an important role in the normal sexual and reproductive development in women. They are also sex hormones. The woman's ovaries make most estrogen hormones, although the adrenal glands and fat cells also make small amounts of the hormones.

Human Physiology/The endocrine system A hormone is a chemical messenger produced by a cell that effects specific change in the cellular activity of other cells (target cells). Unlike exocrine glands (which produce substances such as saliva, milk, stomach acid and digestive enzymes), endocrine glands do not secrete substances into ducts (tubes).

Hormones - Anatomy & Physiology Hormones are signalling molecules produced by endocrine cells which convey information to target cells. When a hormone reaches a target cell, it binds to a receptor to initiate a response. Hormones can be classified by various means, including by their structure and function. Traditionally there are three classifications of hormones: Classical Hormones: secreted from endocrine cells directly into interstitial fluid. These diffuse into the bloodstream to be distributed to all parts of the body served by the circulatory system.
