Of all the body systems, the nervous system is the major control system of homeostasis. It provides monitoring, response, and regulation of all systems in the human body and other organisms. It functions from the tiny level of individual cells to affecting the whole body at once.

Abstract. A major function of the nervous system is to control the relative constancy of the internal environment of the organism. That is, to provide the right chemical environment for living processes to take place. This control of the internal environment is known as homeostasis.

Homeostatic control A negative feedback mechanism is an important type of control that is found in homeostasis. A negative feedback control system responds when conditions change from the ideal or set point and returns conditions to this set point. There is a continuous cycle of events in negative feedback.

Usually, your hypothalamus and autonomic nervous system keep your body within a degree or two of your normal temperature. However, there are times when your body heat rises. This condition is known as heat stress. Heat stress may be due to extreme heat, certain foods, or other factors.

Any interruption to the flow of blood may bring brain damage or death. The nervous system maintains homeostasis by controlling and regulating the other parts of the body. A deviation from a normal set point acts as a stimulus to a receptor, which sends nerve impulses to a regulating center in the brain.

Human body include mechanisms that help regulate the body, this includes organs, glands, tissues and cells. The adjusting of these enables the body to constantly be in a steady state. The main mechanisms of homeostasis are body temperature, body fluid composition, blood sugar, gas concentrations, and blood pressure.

The biological definition of homeostasis is “the tendency of an organism or cell to regulate its internal environment and maintain equilibrium, usually by a system of feedback controls, so as to stabilize health and functioning”. Generally, the body is in homeostasis when its needs are met and its functioning properly.

Cell membranes enable organisms to maintain homeostasis by regulating the materials that may enter or leave a cell. Some materials easily cross the cell membrane without the input of energy; other materials require energy input in order to cross through the cell membrane.
