Document Summary

We talked about some of the elements that are most important to survival. Osmoregulation is the most fundamental of all the survival processes. Osmoregulation was the first set of stressors that an organism would have perceived. The second set of stressors and the second set of the most important elements that are associated with survival are nutrients. We tend to put more emphasis on high quality food than on low quality food. Some foods will be easier to detect than others. It all has to be integrated on a regular basis. Every time you eat, and throughout the day, you are going through this integration. Finally, there is an integration that is made, and you will decide to eat. The hypothalamus acts to coordinate all of the neuroendocrine and endocrine components associated with eating. Gastrin and cholesystokinin play a role with the gut. These are also found in the brain where they play a role with stress and motivational behaviour.
