| Question | Answer |
|---|---|
| Thyroid glands | Produces calcitonin and thyroxine |
| simple goiter | Enlargement of thyroid |
| PTH | Increases blood calcium |
| Mineralocorticoids | Increases blood sodium and decreases body potassium |
| Luteinizing hormone | Ovulating hormone |
| Testerone | Masculinizing hormone |
| Thymosin (Thymus) | Development and function of immune system |
| Melatonin (Pineal) | Regulates the body's internal clock |
| Hyper-secretion | Oversecretion of hormones |
| GH (Anterior Pituitary) | Growth hormone |
| Hormones | chemical mechanism used in endocrine system |
| Endocrinology | study of endocrine system |
| Diabetes mellitus | insulin hypersecretion |
| Prostaglandins | tissue hormone |
| negative feedback | mechanism that reverses direction of change |
| Nonsteroid hormones | hormone synthesized primarily from amino acids |
| Tropic hormones | Tropic hormones: hormones that target other endocrine glands and stimulate their growth and secretion. |
| Sex hormones | hormones that target reproductive tissues. |
| Anabolic hormones | hormones that stimulate anabolism in target cells. |
| Nonsteroid hormones A | which must have cellular receptor proteins at the surface of the plasma membrane. |
| Nonsteroid hormones B | The interaction between nonsteroid hormones and receptor proteins activates a cascade of chemical reactions resulting in the target cell's response to the hormone. |
| Nonsteroid hormones C | Nonsteroid hormones have a quick response |
| Steroid hormones | lipid soluble and can pass directly through the cell membrane of the target cell to react with the receptors inside the cell. |
| Synergism: | this phenomenon occurs when combinations of hormones acting together have a greater effect on a target cell than the sum of the effects that each would have if acting alone. |
| Permissiveness: | this occurs when a small amount of one hormone allows a second one to have its full effects on a target cell. |
| Antagonism: | occurs when a small amount of one hormone produces the opposite effects of another hormone; used to "fine tune" the activity of target cells with great accuracy. |
| Steroid hormones B | are manufactured by endocrine cells from cholesterol. |
| Anabolic steroid | hormones are synthetic substances that are related to the male sex hormones |
| Anabolic steroid B | promote the release of the growth hormone, which stimulates growth, especially skeletal growth. |
| Adrenal Medulla | inner portion of AG secretes epinephrine and noepinephrine |
| Hypothalamus | secretes releasing hormones ADH and Oxytocin |
| Pineal Gland | secretes Melatonin |
| Tropic hormone | stimulates another endocrine gland to grow and secrete hormones |
| Oxytocin | stimulates contraction of uterine muscle |
| sella turcica | small depression of the sphenoid bone shaped like a saddle |
| Antidiuretic hormone (ADH): | prevents the formation of a large volume of urine, thereby helping the body to conserve water |
| Parathyroid hormone (PTH) | acts on bone and the kidneys |
| Pancreatic Islets Alpha cells | secrete the hormone glucagon, which raises the blood glucose levels. |
| Pancreatic Islets Beta cells | secrete the hormone insulin, which serves an antagonistic function to glucagon by lowering blood glucose levels. |
| ovaries secrete | ovaries secrete estrogen, the "feminizing hormone," |
| corpus luteum secretes | progesterone, which assists with the preparation of the uterus for pregnancy. |
| testes produce | the male sex hormone testosterone |
| Thymosin | is a group of hormones produced by the thymus that play a significant role of the body's immune system |
| Melatonin | hormones that the pineal gland, is thought to be related to the body's internal clock and sleep cycle. |
| chorionic gonadotropins | are excreted in the urine. This tropic hormone is secreted by cells of the placenta, and its presence is detected by most pregnancy tests marketed today. |
