Endocrine System

Functions of the Endocrine System
1. Compare the means by which the nervous and endocrine systems regulate body functions.
Chemical Signals
2. Describe the relationship among chemical signals, receptor molecules, and receptor sites.
3. Describe how membrane-bound and intracellular receptor molecules mediate responses to intercellular chemical signals.
4. List the mechanisms by which intercellular chemical signals produce responses in their target tissues.
5. List the major categories of hormones on the basis of their chemical structure.
6. Describe how hormones interact with tissues to produce a response.
7. Describe three methods of regulating the release of hormones.
Endocrine Glands and Their Hormones
8. State the location of each of the endocrine glands in the body.
9. Describe how the hypothalamus regulates hormone secretion from the pituitary.
10. Describe how the pituitary gland regulates the secretion of hormones from other endocrine glands.
11. Choose a hormone and use it to explain how negative feedback results in homeostasis.
12. For each of the major hormones in the chapter, describe the endocrine gland from which it is secreted, its target tissue, the response of the target tissue, and the means by which its secretion is regulated.
13. List the effects of over- and under-secretion of the major hormones.
Other Hormones
14. Describe the functions of hormones secreted by the stomach and small intestine, the functions of prostaglandins, and the functions of erythropoietin.
Age-Related Changes in the Endocrine System
15. Describe the major age-related changes that occur in the endocrine system.
