Due to its distinguishing features and the crucial role that it plays in performing different processes, it has acquired a significant position in physiology. The internal mechanisms of human body are controlled by the constancy of the overall environment called homeostasis. In broader terms it can be said that the different mechanisms of human body perform their functions with the help of constant PH, concentrations of electrolyte and internal body temperature. Homeostasis is basically a controlling system of all the mechanisms which facilitates their smooth activity while maintaining a suitable environment for different functions of brain.
Human brain is the most sensitive area of human body which is easily and frequently affected by the fluctuations in the external environment. However, due to the unique characteristics of homeostasis it remains protected from the external adverse impacts. Recent researchers have identified astonishing factors about homeostasis which further strengthens its position as a key system supporting the brain activities. The internal functions of brain, for instance, transfer of messages through neurons and performance of various other tasks are subject to hypo or hyperactivity if not protected by a supporting and regulating system.
This function of regulating the internal environment and protecting neural circuits from stepping in to a hypo or hyperactive state is actually performed by homeostasis. This substantiates that homeostasis is crucially required for the normal and performance of physiological processes in addition to maintaining an internal body environment which is significantly suitable for all other brain functions (GINA G. TURRIGIANO et al., 2004). Physiological Processes It refer to all the physical processes which supports and guards various activities of living organisms including all the unicellular and multi cellular organisms from their birth to the end of their life.
There are different physiological processes going on simultaneously in the human body including growth and development, bacterial shedding, nutrition processes, movement etc. (PHYSIOLOGICAL PROCESSES, 2009). Homeostasis is yet another type of physiological process which actually maintains a suitable working environment for other physiological processes. The working pattern of homeostasis is further divided into different procedures. For instance, it maintains the acid-base equilibrium and regulates the body temperature through a process called thermogenesis.
Furthermore, it gets the feedback on different body movements through the active involvement of sensory nerves while maintaining a sound water-electrolyte balance through the kallikrein-kinin system (HOMEOSTASIS, 2013). There are various physiological changes which are directly affiliated with homeostasis. For instance, consider an example of aging which is experienced by every individual. It is a physiological change accompanied by other changes as well including increased blood pressure, decreased cardiac activity, etc.
Physiological changes which are particularly related to the mechanism of nervous system include temporary stress and tension, excitement etc. In addition to this other physiological changes which show up as human age increases includes low transference of messages, poor memory, loss of neurons, etc. Homeostasis plays a
