Act @ at distance from the release site. Opposite of exocrine which is secreted outside of the body (mammary gland, lumen of digestive. Endocrine : refers to a hormone that is tract, etc. ) Paracrine: acts on nearby cells, doesn"t" have to travel in the bloodstream. Neuroendocrine: synthesized by nervous tissue and carried in the blood. Gland: cluster of cells organized for synthesis/release of compound (can be endocrine or exocrine. Regulatory chemicals produced in an endocrine gland or scattered, secreted into the blood and carried to its target cell that responds by altering its metabolism. Subjected to tight regulation by feedback from target organs. Regulation of hormones synthesis and mode of action differ greatly based on their structure. Cyclic systems (loops) that control the amount of hormone released. Hypothalamus produces neurohormone that gets secreted into the blood. As the metabolism is increasing, don"t go overboard and go past your point.
