Stimulates the thyroid gland For each target gland/tissue here fill in the correct anterior pituitary hormone Label this diagram with the correct functions of Thyroid Hormone 4. (Page 3.) What are the three targets of PTH? 5. (Page 3.) What is the main ion regulated by PTH? 6. (Page 3.) Match the following adrenal hormones with their functions. _____Cortisol a. Responsible for the reabsorption of Na+ and the secretion of K+ _____Aldosterone b. Responsible for some secondary sex characteristics in females _____Androgens c. Most well known for its role in the immune response _____Epinephrine d. the primary “fight or flight” hormone 7. (Page 3.) All of the hormones secreted by the adrenal cortex are of this chemical composition: 8. (Page 3.) Which of the hormones from the pancreas lowers blood glucose by stimulating glucose uptake by cells? 9. (Page 3.) In the pancreatic islets __________ cells secrete insulin and ________ cells secrete glucagon 10. (Page 3.) Match the following hormones with their functions: _____Inhibin a. Important during pregnancy _____Estrogen b. Responsible for male libido _____Progesterone c. Important in triggering ovulation at the midpoint of the menstrual cycle _____LH d. Important for gamete production and maturation of the female reproductive organs _____Testosterone e. Regulates secretion of FSH by the anterior pituitary 11. (Page 4.) Give the targets and responses of the following hypothalamic hormones: o ADH o TRH o CRH o GnRH o Oxytocin o PIH 12. (Page 4.) How does atrial natriuretic peptide help regulate blood pressure? 13. (Page 4.) Of the following intestinal hormones: CCK, Secretin, GIP, or Motilin, which is responsible for creating peristaltic waves along the length of the intestines? 14. (Page 4.) Which hormone of the kidney stimulates blood cell formation? Actions of Hormones on Target Cells Go to: http://goo.gl/xywW2n 1. (Page 1.) How do hormones influence their target cells? 2. (Page 3.) What are the two ways in which the chemical message of a hormone is converted into a cell response inside the cell? 3. (Page 3.) o a. List the 5 ways in which cells respond to activation by hormones. o b. o c. o d. o e. 4. (Page 3.) Receptors for water-soluble hormones are found on the _______________ of target cells, while receptors for lipid-soluble hormones are found in the ________ or________ of cells. Target cells tend to ______________ ________________ the number of their receptors when there are sustained high levels of hormone present. 5. (Page 3.) 6. (Page 3.) True or False: All cells have receptors for all hormones. 7. (Page 4.) Put the steps of the cAMP second messenger system in the correct chronological sequence. (#1 to #5) ______G-protein binds to adenylate cyclase which converts ATP into cAMP. ______Activated protein kinases elicit the cell response. ______Hormone binds with Receptor. ______cAMP phosphorylates protein kinases. _______Receptor changes shape and activates G-protein. 8. (Page 4.) ______________ is the process whereby a single hormone can elicit the response of many second messengers within single target cell. 9. (Page 4.) Complete this sequence: hormonereceptorG-protein______________ IP3 and ___________. 10. (Page 4.) When insulin binds to a tyrosine kinase receptor on its target cell what is the main result? 11. (Page 5.) o a. List the main stimuli for insulin secretion. o b. o c. o d. 12. (Page 5.) How is insulin transported through the blood? 13. (Page 5.) What are the two major functions of insulin? 14. (Page 6.) ________ diabetes is characterized by insulin absence or deficiency, while ________ diabetes is caused by resistance of target cells to the action of insulin. 15. (Page 6.) Excess glucose in the urine is known as __________ 16. (Page 7) When a lipid soluble hormone binds to its receptor molecule it acts as a 17. (Page 7) Put these events in the correct chronological sequence. (#1 to #%) ______mRNA is transcribed. ______New protein is synthesized in the cell. ______Cortisol binds to receptor-chaperone complex. ______Hormone-receptor complex binds to DNA. ______Cell response is initiated.
