Allostasis is the process of achieving stability, or homeostasis, through physiological or behavioral change. This can be carried out by means of alteration in HPA axis hormones, the autonomic nervous system, cytokines, or a number of other systems, and is generally adaptive in the short term (McEwen & Wingfield 2003).
Homeostasis is the internal maintenance of a stable internal environment-temperature, amount of water and amount of glucose. If temperature is too high, the enzymes could become denatured.Too low, and metabolic processes will be too slow.omeostasis is the internal maintenance of a stable internal environment-temperature, amount of water and amount of glucose.
