to stay the same

secretions that leave the body, secretions onto external surface of body (sweat, sebrum, cerumen, saliva, digestive secretions)

secretions into surround fluid or into the bloodstream

Any detectable change in the environment

any substance secreted by a group of cells that have a tropic effect (changes in physiology) on a distant cell

any cell that has receptors for a specific hormone

intergral membrane proteins on surface of target cell. When a hormone binds to receptor it causes a signal using a 2nd messanger system (G-protein)

a protein in cytoplasm in a target cell. When a hormone binds it alters protein synthesis of a target cell

proteins in the nucleus of a target cell. When a hormone binds it alters protein synthesis of a target cell

converting a signal into a phisological response
