Almost any kind of threat to homeostasis or stress will cause plasma glucocorticoid levels to rise. The increased levels have traditionally been ascribed the physiological function of enhancing the organism's resistance to stress, a role well recognized in glucocorticoid therapy. How the known physiological and pharmacological effects of glucocorticoids might accomplish this function, however, remains a mystery. A generalization that is beginning to emerge is that many of these effects may be secondary to modulation by glucocorticoids of the actions of numerous intercellular mediators, including established hormones, prostaglandins and other arachidonic acid metabolites, certain secreted neutral proteinases, lymphokines, and a variety of bioactive peptides. These mediators participate in physiological mechanisms--endocrine, renal, immune, neural, etc.--that mount a first line of defense against such challenges to homeostasis as hemorrhage, metabolic disturbances, infection, anxiety, and others. Contrary to the traditional view that glucocorticoids enhance these defense mechanisms, however, it has become increasingly clear that glucocorticoids at moderate to high levels generally suppress them. This paradox, which first emerged when glucocorticoids were discovered to be antiinflammatory agents, remains a major obstacle to a unified picture of glucocorticoid function. We propose that stress-induced increases in glucocorticoid levels protect not against the source of stress itself but rather against the body's normal reactions to stress, preventing those reactions from overshooting and themselves threatening homeostasis. This hypothesis, the seeds of which are to be found in many discussions of particular glucocorticoid effects, immediately accounts for the paradox noted above. Furthermore, it provides glucocorticoid physiology with a unified conceptual framework that can accommodate such apparently unrelated physiological and pharmacological effects as those on carbohydrate metabolism, inflammatory processes, shock, and water balance. It also leads us to suggest that some of the enzymes rapidly induced by glucocorticoids, such as glutamine synthetase, detoxify mediators released during stress-induced activation of primary defense mechanisms. These mediators would themselves lead to tissue damage if left unchecked.

Q. Last year my doctor diagnosed that my kidney was not functioning well. Can anyone help me? I’m 50 year old male. Last year my doctor diagnosed that my kidney was not functioning well. I intake western medicine for past one year, but I’m not satisfied with that. I like to move to some other treatment. Can anyone help me? A. Hello Jude, I understand your problem and I do have a similar issue. Initially I was trying with the western meds and it did not give me the desired results. I have skipped them now and have been taking Chinese herbal medicine and trust me I feel much better. Consult a TCM doctor before taking any supplements to improve your kidneys. I wish you to get well soon!!!

Human physiology seeks to understand the mechanisms that work to keep the human body alive and functioning, [3] through scientific enquiry into the nature of mechanical, physical, and biochemical functions of humans, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems within systems. The endocrine and nervous systems play major roles in the reception and transmission of signals. that integrate function in animals. Homeostasis is a major aspect with regard to such interactions within plants as well as animals. The biological basis of the study of physiology, integration refers to the overlap of many functions of the systems of the human body, as well as its accompanied form. It is achieved through communication that occurs in a variety of ways, both electrical and chemical. [ citation needed ]

Now, in the Organ of Corti, we have a number of different hair cell s. We have inner hair cell s, which would be this one here; and we have outer hair cell s, which would be these four here. Now, as you can ima gine, if the entire Organ of Corti is moving up-and-down, the tectorial membrane is moving in a windshield-wiper-like fashion, that tectorial membrane is going to cause this outer part of the hair cell s to vibrate. And these outer parts are called cilia . So, it’s going to cause the cilia to bend. And that’s the process that’s going to cause a signal to go via the auditory nerve to the brain.
