Stress and Health: Biological and Psychological Interactions is a brief and accessible examination of psychological stress and its psychophysiological relationships with cognition, emotions, brain functions, and the peripheral mechanisms by which the body is regulated. Updated throughout, the Third Edition covers two new and significant areas of emerging research: how our early life experiences alter key stress responsive systems at the level of gene expression; and what large, normal, and small stress responses may mean for our overall health and well-being.

Homeostatic Regulation: Normal Function and Stress Responses
Homeostatic Regulation: Normal Function and Stress Responses
Chapter objectives
  • Understand the concept of homeostasis as the result of systems that regulate the state of the vital organs to maintain life.
  • Recognize that homeostasis is maintained by layers of physiological regulation from individual organs up through the brainstem and hypothalamus.
  • Understand the basic organization of the autonomic nervous system and its control by the brainstem.
  • Learn the endocrine response to stress and its regulation by the hypothalamus.
  • Understand the role of the hypothalamus in integrating autonomic and endocrine responses to stress.

In preparation for a discussion of stress, we should first review the mechanisms the body uses to maintain homeostatic function during more normal periods. We can divide homeostatic regulation into five layers beginning ...
