hormone that can't penetrate a cell wall, must bind to
receptors and activate a "secondary messenger hypothalamus synthesize releasing or inhibiting
system" - ANSWER -protein (nonsteroidal) hormones that stimulate or inhibit this gland to
hormone secrete or suppress secretion of the hormones it
produces - ANSWER -anterior pituitary gland
factors that affect target cell activation by a hormone
