Cells typically communicate using chemical signals. These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. There, they can float – like messages in a bottle – over to neighboring cells.

WebWhat do hormones do? Hormones are chemical messengers that affect and manage hundreds of bodily processes. Often, a bodily process involves a chain reaction of several different hormones. A hormone will only act on a part of your body if it “fits” — if the cells in the target tissue have receptors that receive the message of the hormone.

IP3, DAG, and Ca are second messengers in the phosphoinositol pathway. The pathway begins with the binding of extracellular primary messengers such as epinephrine, acetylcholine, and hormones AGT, GnRH, GHRH, oxytocin, and TRH, to their respective receptors.
