in which a hormone binds to receptors on and affects the function of the cell type that produced it.nParacrine:a type of hormone function in which hormone synthesized in and released from endocrine cells binds to its receptor in nearby cells of a different type and affects their function.nEndocrine:applied to organs and structures that release their products into the blood or lymph,and to substances(hormones)that exert specific effects on other organs.分泌的種類Autocrine:a mode of
