Natural hormones
I. Natural hormones are active substances formed in living tissues of humans or animals, capable of inhibiting or stimulating the functions of various organs in very small quantities by directly acting on them or controlling the synthesis or secretion of secondary or tertiary hormonal systems. The main defining characteristic of a hormone is its ability to stereospecifically bind to a receptor molecule to perform the hormonal action. Secretion of these substances, usually by endocrine glands, is regulated by the sympathetic and parasympathetic systems. Hormones are transported
by blood, lymph, or other bodily fluids. They may also be produced in endocrine and exocrine glands or in various cellular tissues. The transport of hormones via blood is not necessary for the hormonal effect. The effect can occur after the release of hormones into the intercellular fluid and their subsequent binding to receptors on neighboring cells (paracrine regulation) or to receptors on the cells releasing the hormone (autocrine regulation)
