hormone, endocrine, internal secretion(noun)
the secretion of an endocrine gland that is transmitted by the blood to the tissue on which it has a specific effect
(Physiological Chem.) a chemical substance, whether natural or synthetic, that functions like a hormone in a living organism. Thus, synthetic steroid hormones may be more effective than their natural counterparts.
(Bot.) A substance that controls growth rate or differentiation in plants; also called phytohormone. The most well-known are the auxins that stimulate growth at the growing tips of plants, and control root formation and the dropping of leaves; and the gibberellins, which are used in agriculture to promote plant growth.
(Physiological Chem.) A chemical substance formed in one organ and carried in the circulation to another organ on which it exerts a specific effect on cells at a distance from the producing cells; thus, pituitary hormones produced in the brain may have effects on cells in distant parts of the body..
Origin: [From Gr. "orma`ein to excite.]
Any substance produced by one tissue and conveyed by the bloodstream to another to effect physiological activity.
A synthetic compound with the same activity.
Any similar substance in plants.
A hormone is a chemical released by a cell, a gland, or an organ in one part of the body that affects cells in other parts of the organism. Generally, only a small amount of hormone is required to alter cell metabolism. In essence, it is a 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. Endocrine hormone molecules are secreted directly into the bloodstream, typically into fenestrated capillaries. Hormones with paracrine function diffuse through the interstitial spaces to nearby target tissues. A variety of exogenous chemical compounds, both natural and synthetic, have hormone-like effects on both humans and wildlife. Their interference with the synthesis, secretion, transport, binding, action, or elimination of natural hormones in the body can change the homeostasis, reproduction, development, and/or behavior, just as endogenously produced hormones do.
A type of substance naturally created by a living organism and naturally created within the body of an animal or human being.
Both animals and human beings naturally create their own hormones essential for growth, regulation with their bodies etc.Submitted by MaryC on January 30, 2020
