A type of chemical messenger (peptide), occurring both in plants and animals, that acts to inhibit or excite metabolic activities (in that plant or animal) by binding to receptors on specific cells to deliver its “message.” A hormone’s site of production is distant from the site of biological activity (i.e., where the message is delivered).<\/p>\n
Chemical substances secreted by a variety of body organs that are carried by the bloodstream and usually influence cells some distance from the source of production. Hormones signal certain enzymes to perform their functions. In this way, hormones regulate such body functions as blood sugar levels, insulin levels, the menstrual cycle, and growth.<\/p>\n

A substance released from a gland (such as the adrenal or thyroid gland) or cells in one part of the body that is transported in the blood and affects distant organs or cells. Examples include epinephrine, norepinephrine, and thyroxin.<\/p>\n
A chemical substance produced by a group of cells or an organ, called an endocrine gland, that is released into the blood and transported to another organ or tissue, where it performs a specific action. Examples of hormones are insulin, estrogen, testosterone, and adrenalin.<\/p>\n
Chemicals that are manufactured and secreted by the endocrine glands that are essential for regulating specific body functions.<\/p>\n
A substance which is produced by one part of the body, especially the endocrine glands and is carried to another part of the body by the bloodstream where it has particular effects or functions.<\/p>\n
Chemical substances secreted by various endocrine or ductless glands directly into the blood stream to regulate the functions of other organs.<\/p>\n
A chemical substance that is secreted into body fluids and transported to another organ, where it produces a specific effect on metabolism.<\/p>\n
A substance synthesized and released by an endocrine cell, carried by the blood and having its site of action distal to its site of origin. There are some \u201clocal\u201d hormones that are secreted and have as their site of action the same tissue. The eicosanoids are typical of this group of hormones.<\/p>\n
A hormone is a chemical produced in an endocrine gland that exhibits its effects at another site. Hormones can be polypeptides, amino acid derivatives, or lipid derivatives.<\/p>\n
A wide variety of chemicals produced by organs to help control various body functions, including metabolism, growth (see growth and growth disorders, development of secondary sex characteristics, a woman\u2019s menstrual cycle, a man\u2019s sperm production, the changes involved in pregnancy and lactation, and the general circulatory system. Some hormones are produced by body organs such as the kidneys or intestines (and during pregnancy, the placenta), but most are produced by the endocrine system, among them the hypothalamus, pituitary gland, thyroid gland, parathyroid glands, thymus, adrenal glands, and the sex organs called gonads (testes in the male and ovaries in the female).<\/p>\n
Complex chemical produced and secreted by endocrine (ductless) glands that travels through the bloodstream and controls or regulates the activity of another organ or group of cells\u2014its target organ. (For example, growth hormone released by the pituitary gland controls the growth of long bones of the body.) There are two main types of hormones\u2014 steroids (e.g., estrogen, testosterone, aldosterone, cortisol) and nonsteroidal. Secretion of hormones is regulated by feedback mechanisms and neurotransmitters.<\/p>\n
Chemical messenger found in the blood.<\/p>\n
A chemical, produced by certain cells or organs of the body, that specifically regulates various physical processes.<\/p>\n
Chemicals produced by glands in the endocrine system and released directly into the bloodstream to perform specific functions elsewhere throughout the body. Hormones balance each other in the bloodstream and control many vital functions of the body. Interference or disturbance in a person’s hormonal equilibrium can affect normal growth and overall health and may even endanger survival.<\/p>\n

Hormones balance each other in the bloodstream and control many vital functions of the body. Interference or disturbance in a person’s hormonal equilibrium can affect normal growth and overall health and may sometimes endanger survival.<\/p>\n
A substance that is produced in one part of the body (by an endocrine gland, such as the thyroid, adrenal, or pituitary), passes into the bloodstream and is carried to other (distant) organs or tissues, where it acts to modify their structure or function. Examples of hormones are corticosteroids (from the adrenal cortex), growth hormone (from the pituitary gland), and androgens (from the testes).<\/p>\n
A chemical substance, produced in the body and secreted internally, usually into the blood, which has effects on organs other than those in which it is produced. Most hormones are produced by endocrine organs.<\/p>\n
These are \u2018chemical messengers\u2019 that are dispersed by the blood and act on target organs to produce effects distant from their point of release. The main organs involved in hormone production are the pituitary gland, pancreas, ovary, testis, thyroid gland, and adrenal glands. The release of many hormones is, ultimately, under the control of the central nervous system via a series of inhibiting and releasing mechanisms from the hypothalamus. Hormones are involved in maintaining homeostasis: for example, insulin regulates the concentration of glucose in the blood. They also participate in growth and maturation: for example, growth hormone promotes growth and helps to regulate fat, carbohydrate, and protein metabolism; and the sex hormones promote sexual maturation and reproduction.<\/p>\n
A substance originating in an organ, gland, or body part, conveyed through the blood to another body part, and chemically stimulating that part to increase or decrease functional activity or to increase or decrease secretion of another hormone.<\/p>\n
According to the classical definition, a chemical secreted in the blood which acts on cells elsewhere in the body. However, the revised definition is a chemical secreted by body cells (including brain cells) which diffuses into the body fluids to act on other cells both near and distant.<\/p>\n
A substance produced in the body by an organ or cells of an organ and transported to another organ where it has a specific regulatory effect.<\/p>\n
Substance that is secreted by a cell that acts to regulate the activity of other cells.<\/p>\n
Chemical messenger released into the bloodstream that controls many body activities.<\/p>\n
Secretions, such as insulin, adrenaline, and estrogen, that stimulate functional activity or other secretions in the body. Hormones influence the welfare of the entire body.<\/p>\n
A chemical made by glands in the body. Hormones circulate in the blood-stream and control the actions of certain cells or organs. Some hormones can also be made in a laboratory.<\/p>\n
A substance that acts as a chemical messenger in the body.<\/p>\n
Biochemical messengers secreted into the bloodstream by organs and glands that act on their respective target cells and organs.<\/p>\n
Chemical substances produced in one part or organ of the body that trigger or regulate the activity of an organ or group of cells in another part of the body.<\/p>\n
A chemical substance, usually a protein or steroid, that is secreted by an endocrine gland and transported by the circulatory system throughout the body. Upon making physical contact with a target cell, the hormone enters the cell and induces changes in metabolism, growth rate, protein synthesis, or synthesis of other compounds. The changes the hormone induces can have profound effects on body function.<\/p>\n
A biochemical communicator generated by a specific cell type, which circulates within the bloodstream to modify the metabolic processes of another distinct cell type.<\/p>\n
A hormone is a type of chemical messenger discharged into the bloodstream by glands or tissues to produce specific effects on other tissues within the body, thereby modifying their activity. These hormones play a vital role in regulating various bodily functions, such as cellular metabolism, growth, sexual development, and the body’s response to stress or illness.<\/p>\n
Numerous hormones are synthesized by endocrine glands. The major endocrine glands, such as the pituitary, thyroid, parathyroid, adrenal glands, pancreas, ovaries, and testes, have a primary function of producing various hormones. Additionally, hormones are secreted by other organs, including the brain, kidneys, intestines, and, during pregnancy, the placenta.<\/p>\n
Chemical compounds produced by the endocrine glands, released into the bloodstream, where they travel and enact specific alterations in distant organs.<\/p>\n
Chemical compounds naturally produced by the body that regulate various physiological processes, depending on the specific hormone. Some hormones are responsible for the physical changes that occur during puberty, and these are the ones associated with the development of acne.<\/p>\n
