Any hormone that stimulates the nervous system.
(physiology) Any substance produced by one tissue and conveyed by the bloodstream to another to effect physiological activity.
a hormone that is released by nerve impulses (e.g., norepinephrine or vasopressin)
(pharmacology) A synthetic compound with the same activity.
A neurohormone is any hormone produced and released by neuroendocrine cells (also called neurosecretory cells) into the blood. By definition of being hormones, they are secreted into the circulation for systemic effect, but they can also have a role of neurotransmitter or other roles such as autocrine (self) or paracrine (local) messenger.The hypothalamus releasing hormones are neurohypophysial hormones in specialized hypothalamic neurons which extend to the median eminence and posterior pituitary.
Any similar substance in plants.
To treat with hormones.
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..
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.
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.
the secretion of an endocrine gland that is transmitted by the blood to the tissue on which it has a specific effect
A hormone (from the Greek participle ὁρμῶν, ) is any member of a class of signaling molecules in multicellular organisms, that are transported to distant organs to regulate physiology and behavior. Hormones are required for the correct development of animals, plants and fungi.
