     Title: Hormones



1.   a.   How do hormones affect long-term coordination of body activities?




     b. In what ways are hormones distinguished from each other?




2.   The pineal gland secretes melatonin. Explain the function of melatonin.




3.   a.   What stimulates Parathyroid Hormone secretion?




     b. Bone osteoclasts are one PTH target. Describe the affect of PTH on
        these cells, and the corresponding affect on body homeostasis.




     c.   Kidney nephrons are also PTH targets. Describe the affect of PTH on these structures, and the
          corresponding affect on body homeostasis.
4.   What are the functions of each of the following hypothalamic hormones?

     a.   Releasing Hormones




     b. Oxytocin




     c.   Antidiuretic Hormone (ADH)




5.   What are the functions of each of the following pituitary hormones?

     a.   Human Growth Hormone (hGH)




     b. Thyroid Stimulating Hormone (TSH)




     c.   Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH)




     d. Prolactin (PRL)




     e.   Adrenocorticotropic Hormone (ACTH)




     f.   Melanocyte-Stimulating Hormone (MSH)
6.   Describe the functions of thyroid hormones (T3 and T4).




7.   Describe the function of thymic hormones.




8.   The heart secretes Atrial Natriuretic Hormone (ANP). Describe its
     functions.




9.   The G cells of the gastric mucosa produce the hormone gastrin and the duodenal
     mucosa produces secretin and cholecystokinin (CCK). What are the functions of
     these hormones?

     a.   Gastrin




     b. Secretin




     c.   Cholecystokinin (CCK)
10.   Pancreatic alpha cells secrete glucagon, while the beta cells secrete
      insulin. Describe the functions of these hormones.

      a.   Glucagon




      b. Insulin




11.   Ovarian follicle cells and corpus luteum produce estrogens, progesterone,
      relaxin, and inhibin. Describe the function of these hormones.

      a.   Estrogens




      b. Progesterone




      c.   Relaxin




      d. Inhibin




12.   Within the testes, the Leydig cells produce testosterone while the Sertoli cells produce inhibin.
      Describe the function of these hormones.

      a.   Testosterone




      b. Inhibin
13.   How do lipid soluble hormones work to alter cell function?




14.   How do water soluble hormones work to alter cell function? (This includes an
      explanation of “second messenger” function.)




15.   Explain how circulating hormones affect their targets.




16.   Explain how eicosanoids, growth factors, and nitric oxide are examples
      of local hormones.
