1 Name: Chapter 13 worksheet The Endocrine System Please label the: hypothalamus pineal gland pituitary gland thyroid gland parathyroid gland thymus heart stomach liver adrenal glands kidneys pancreas small intestines ovaries, uterus testes skin Where do the exocrine glands secrete their products and what are some examples? Where do the endocrine glands secrete their products and what are some examples? What are target cells? What do they have that other cells don t which allow hormones to affect them? Please list the lipid soluble hormones: What are steroid hormones made from?
2 What are water soluble hormones made from? Where are the receptor cells located for lipid soluble hormones? Where are the receptor cells located for water soluble hormones? Hypothalamus and Pituitary Gland What is considered the master gland? What is the link between the nervous and the endocrine systems? What nine hormones do cells in the hypothalamus synthesize? Circle the anterior pituitary. Draw a square around the posterior pituitary. Draw the hypothalamic neurosecretory cells
3 Location Hormone Action Anterior Pituitary Human Growth (hgh) Thyroid-stimulating (TSH) Follicle-stimulating (FSH) Luteinizing (LH) Prolactin (PRL) Posterior Pituitary Adrenocorticotropic (ACTH) corticotropin Melanocyte-stimulating (MSH) Oxytocin Antidiuretic (ADH) Vasopressin Please use the table on p. 323 to summarize the actions of these hormones. Where are the posterior pituitary hormones synthesized and packaged? How do they get to the posterior pituitary? How is the amount of ADH regulated? How is osmotic pressure related to solutes dissolved in the blood? Thyroid Gland What thyroxine and how many atoms of iodine does it require? Why is iodized salt important in one s diet? How many atoms of iodine does triiodothyrodine contain? Where is calcitonin produced in the body? What effect does the thyroid hormones have on the body? The first domino that falls affects the other dominoes in a line. The effect of the first one falling is that the other dominoes fall. What regulates thyroid production from the hypothalamus? What regulates thyroid production from the anterior pituitary?
4 What affect does calcitonin have on the body? Review the steps of the regulation of secretion thyroid hormones using the diagram on the left. What is the effect of thyroid hormone on metabolic rate? Which cells secrete T4 and which secrete T3? Which cells secrete calcitonin? Parathyroid Gland Where is the parathyroid gland located? What are the secretory cells called? What is the parathyroid hormone (PTH) responsible for? What happens if levels are high? What does it prevent? Parathyroid Hormone (PTH) vs. Calcitonin osteoclasts blood calcium *affects kidneys and intestines, too (please fill in the blanks) osteoclasts blood calcium
5 Pancreatic Islets Where is the pancreas? What cells are involved in the endocrine functions? What do alpha cells secrete? What do beta cells secrete? What are the actions of glucagon? What are the actions of insulin? Hyperglycemia cells secrete converts blood sugar Hypoglycemia cells secrete converts blood sugar Please label the spleen, the pancreas, the capillary cells, the exocrine cells, the endocrine alpha cells, and endocrine beta cells. Draw a line across the islet.
6 Adrenal Glands Where are the adrenal glands located? What is the outer region called? What is the inner region called? Label the adrenal gland right and left, renal artery right and left, renal vein right and left, inferior vena cava, and the abdominal aorta. What hormone does the outer region produce? What does it effect? What does the middle region produce? What does it effect? What does the inner region produce? What affect does it have? What does aldosterone regulate? What drug is used to decrease the risk of tissue rejection with transplants? Besides the adrenal glands, where else are androgens released? How is the adrenal medulla part of the nervous system?
7 Ovaries and Testes What do the ovaries and tested secrete? What are gonads? Where are FSH and LH produced? Pineal Gland Where is it located? What does it secrete? When? What does it help regulate? Other Hormones What are leukotrienes? What is their function? What are prostaglandins? What is their function? How do NSAIDS work?
