Document Summary

Homeostasis: introduction to the autonomic nervous system and endocrine system (sept. 30, oct. 3). Define and identify the main characteristics of homeostasis. Compare the functional differences between the sympathetic and parasympathetic divisions of the ans. Distinguish between exocrine and endocrine glands, and localize the major endocrine glands. Describe the different structural classes of hormones and their mechanisms of action. Describe the functional organization of the hypothalamic-pituitary axis: homeostatic: ans & endocrine system. Most disease seen as a disturbance of homeostasis imbalance. Aging associated with progressive decrease in our ability to maintain homeostasis.
