Hormonal regulation of hormone release involves a hormone binding to its receptor on an endocrine cell to regulate hormonal secretion. A hormone that stimulates hormone secretion is called a tropic hormone. Tropic hormones may also stimulate proliferation of endocrine cells.Recall that endocrine secretion is whatever occurs to increase the amount of hormone in the circulation). An example is the hormone adrenocorticotropic hormone (ACTH) that stimulates secretion of the steroid hormone cortisol by cells of the zona fasciculata in the adrenal cortex.
