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).
11. Homeostasis is the body process that attempts to maintain balance of internal environment variables such as pH, temperature, and blood sugar levels because cells and organs function properly in only a narrow range of conditions. 12.All cells have a cell membrane.he body attempts to maintain internal temperatures within this range though the process of homeostasis. However, in cases of exposure to extreme heat or cold, the homeostatic balance is disturbed, and cell die-off, organ damage, or even death can result. 2.
