Hormone secretion can be stimulated and inhibited by: 1  Other hormones (stimulating- or releasing -hormones) 2  Plasma concentrations of ions or nutrients, as well as binding globulins. 3  Neurons and mental activity.  Environmental changes, e.g., of light or temperature.
For example, the pituitary gland (endocrine gland) secretes thyroid-stimulating hormone, which acts on the target organ, the thyroid gland, to stimulate production of the thyroid hormones T3 and T4.The pituitary then monitors the circulating levels of thyroid hormones.n negative feedback, the endocrine gland has a natural tendency to over-secrete its hormone. The hormone then stimulates the target tissue to perform a function. Thus, the important factor is not the rate of secretion of the hormone but the rate that the target function is performed.
