👉 In medical terminology, "exocrinology" refers to the study of the function and regulation of hormones in the body. Specifically, it is a branch of medicine that studies how the body's cells, organs, and tissues respond to hormones, including those produced by the pituitary gland, adrenal glands, thyroid gland, pancreas, and other glands. The focus is on understanding the mechanisms behind hormonal signaling, which can affect various bodily functions such as growth, metabolism, and energy production.
