Hormone specificity explains how each hormone can have specific effects in widespread parts of the body. Many hormones produced by the endocrine system are classified as tropic hormones.A tropic hormone is a hormone that is able to trigger the release of another hormone in another gland.Tropic hormones provide a pathway of control for hormone production as well as a way for glands to be controlled in distant regions of the body.
