| Hormones | Chemical substances that are secreted by endocrine cells into the extracellular fluids and regulate the metabolic activity of the other cells in the body. |
| Steroids | Include sex hormones made by the gonads and the hormones produced by the adrenal cortex. |
| Prostoglandins | Local hormones made from highly active lipids released from nearly all the cell membranes. |
| Pituitary Gland | Endocrine gland about the size of a pea. |
| Tropic Hormones | Made up of the thyrotropic hormone, adrenocorticotropic hormone, and the two gonadtropic hormones, these stimulate the target organs to secrete their hormones. |
| Growth Hormone | A general meatbolic hormone resposible for increase in size of skeletal muscles and long bones. |
| Prolactin | Hormone that stimulates milk production following childbirth. |
| Adrenocortioctropic Hormone | Regulates the endocrine activity of the cortex portion of the adrenal gland. |
| Follicle-Stimulating Hormone | Stimulates follicle development in the ovaries. |
| Luteinizing Hormone | Triggers ovulation of an egg from the ovary and causes the ruptured follicle to produce progesterone and some estrogen. |
| Neurosecretory Cells | Translate neural signals into chemical stimuli. |
| Oxytocin | It simluates powerful contractions of the uterine muscle during labor, during sexual relations, and breastfeeding. |
| Antidiuretic Hormone | A chemical that inhibits or prevents urine production. |
| Vasopressin | Hormone that can stimulate contraction of arteries and capillaries. |
| Thyroid Hormone | Mixture of thyroxine and triiodothyronine that controls the rate at which glucose is burned. |
| Calcitonin | Produced by the thyroid gland, this hormone decreases blood calcium levels by by causing calcium to be deposited in the bones. |
| Parathyroid Hormone | Stimulates the release of calcium ions from bone tissue into the blood. |
| Corticosteroids | A group of steroids produced in the adrenal cortex made up of mineralocorticoids, glucocorticoids, and sex hormones. |
| Aldosterone | Regulates concentrations of sodium and potassium ions in blood. |
| Catecholamines | The group of hormones produced by the adrenal medulla which consists of epinephrine and norepinephrine. |
| Insulin | Hormone that removes glucose from the blood to store as gycogen. |
| Glucagon | A hormone secreted by the pancreas which increases blood glucose levels. |
| Melatonin | Secreted by the pineal gland; it maintains the body's circadian rhythm. |
| Thymosin | A hormone produced by the thymus which is used for the development of white blood cells called T lymphocytes. |
| Estrogens | Responsible for the development of sex characteristics in women. |
| Progeserone | Prepares the uterine wall for embryo implantation. |
| Testoserone | Responsible for sperm formation and male sex characteristics. |
| Human Chorionic Gonadotropin | Produced by the developing embryo. It stimulates the ovaries to continue producing estrogen and progesterone. |
| Human Placental Lactogen | Prepares the breast for lactation. |
| Relaxin | Allows the mother's pelvic ligaments to become more flexible in birth. |
| Menopause | The point at which menstruation ceases, and marks the end of a woman's fertility. |
