Description of homeostasis

Question

Give a brief description of homeostasis? What are the controllers, sensors and effectors of the homeostasis?

Answer 1

Homeostasis comprises the procedures by which the organism controls adequate intra and extracellular situation to keep probable the normal reactions of metabolism.

Homeostatic sensors are structures which detect information from inner and outer environment of body. These sensors might be nervous receptor cells, cytoplasmic or membrane proteins and other specialized molecules.

Controllers are structures liable for processing and interpreting information received from sensors. Controllers in general are specialized regions of central nervous system however on the molecular level there are also some of them, like DNA, a molecule which can receive information from proteins to inhibit or stimulate expression of some genes. Effectors are elements commanded by controllers that have the function of bringing about actions that in fact maintain and control the equilibrium of the organism, such as glands, muscles, cellular organelles, and so forth., and in the molecular level structures which participate in genetic translation, produced proteins, and so forth.
