| Steroid Hormones | A class of hormones each of which is composed of four interconnected rings of carbon atoms |
| nongenomic effect | an effect of a steroid hormone that is not mediated by direct changes in gene expression |
| Tropic hormones | A class of anterior pituitary hormones that affect the secretion of other endocrine glands |
