CHAPTER 13 BLM 13.1.2 OVERHEAD Glands and Their Secretions Endocrine gland hypothalamus anterior pituitary posterior pituitary thyroid parathyroid adrenal cortex adrenal medulla pancreas ovaries Hormone secreted hypothalamic releasing- and inhibiting-hormone human growth hormone (hgh) thyroid-stimulating hormone (TSH) adrenocorticotropic hormone (ACTH) follicle-stimulating hormone (FSH) luteinizing hormone (LH) prolactin (PRL) antidiuretic hormone (ADH) oxytocin (OCT) thyroxine (T 4 ) calcitonin parathyroid hormone (PTH) glucocorticoids (e.g., cortisol) mineralocorticoids (e.g., aldosterone) gonadocorticoids epinephrine and norepinephrine insulin glucagon estrogen progesterone Effects of hormone on target tissues/organs regulates anterior pituitary hormones stimulates cell division, bone and muscle growth, and metabolic functions stimulates the thyroid gland stimulates the adrenal cortex to secrete glucocorticoids stimulates production of ova and sperm from the ovaries and testes stimulates sex hormone production from the ovaries and testes stimulates milk production from the mammary glands promotes the retention of water by the kidneys stimulates uterine muscle contractions and release of milk by the mammary glands affects all tissues increases metabolic rate and regulates growth and development targets bones and kidneys to lower blood calcium from bone and reabsorption of calcium by kidneys raises blood calcium levels by stimulating the bone cells to release calcium, the intestine to absorb calcium from food, and the kidneys to reabsorb calcium stimulate tissues to raise blood glucose and break down protein promote reabsorption of sodium and water by the kidneys promote secondary sexual characteristics fight-or-flight hormones raise blood glucose levels lowers blood glucose levels and promotes the formation of glycogen in the liver raises blood glucose levels stimulates uterine lining growth and promotes development of the female secondary sexual characteristics promotes growth of the uterine lining and prevents uterine muscle contractions testes testosterone promotes sperm formation and development of the male secondary sexual characteristics
CHAPTER 13 BLM 13.1.3 OVERHEAD Secretion of ADH A negative feedback mechanism controls the secretion of ADH from the hypothalamus.
CHAPTER 13 BLM 13.1.4 OVERHEAD Regulatory Pathway of Tropic Hormones The generalized regulatory pathway of tropic hormones. The target gland hormone will affect other tissues in the body such as the bones and muscles. How are tropic hormones regulated by negative feedback?
CHAPTER 13 BLM 13.2.1 OVERHEAD hgh Targets The targets of hgh in the body. Why is hgh considered a tropic hormone?
CHAPTER 13 BLM 13.2.2 HANDOUT Hormones of the Pituitary Gland Provide labels for the following diagram. 1. 7. 13. 2. 8. 14. 3. 9. 15. 4. 10. 16. 5. 11. 17. 6. 12. 18.
CHAPTER 13 BLM 13.2.4 HANDOUT Thyroid Gland Provide labels for diagram A above: 1. 2. What is shown in diagrams B and C above? What structures or substances are represented by A E in the diagram to the right? A. B. C. D. E. 1. 2. 3. 4. 5.
CHAPTER 13 BLM 13.2.5 HANDOUT Parathyroid Glands Negative feedback mechanisms regulate the concentration of calcium in the blood by parathyroid hormone (PTH). When blood concentration of calcium (Ca 2+ ) is low, PTH is released by the parathyroid glands. PTH directly stimulates the breakdown of bone and the reabsorption of Ca 2+ by the kidneys. It indirectly promotes the absorption of Ca 2+ in the intestine by stimulating the production of vitamin D.
CHAPTER 13 BLM 13.3.1 HANDOUT The Adrenal Glands Provide labels for the following diagrams. 1. 6. 2. 7. 3. 8. 4. 9. 5. 10.
CHAPTER 13 BLM 13.3.2 OVERHEAD Hormonal and Nervous System Interaction in the Stress Response Interactions between the sympathetic nervous system and the endocrine (hormonal) system in the short-term stress response.
CHAPTER 13 BLM 13.3.3 HANDOUT Short- and Long-term Stress Responses Provide labels for the following diagram. 1. 8. 2. 9. 3. 10. 4. 11. 5. 12. 6. 13. 7. 14.
CHAPTER 13 BLM 13.4.1 HANDOUT The Pancreas Provide labels for the following diagram. 1. 7. 2. 8. 3. 9. 4. 10. 5. 11. 6. 12.
CHAPTER 13 BLM 13.4.2 HANDOUT Regulating Blood Glucose Provide labels for the following diagram. 1. 7. 2. 8. 3. 9. 4. 10. 5. 11. 6.
