The homeostatic mechanism which controls the plasma sodium concentration is rather more complex than most of the other homeostatic mechanisms described on this page. The sensor is situated in the juxtaglomerular apparatus of kidneys, which senses the plasma sodium concentration in a surprisingly indirect manner.
Acid–base homeostasis is the homeostatic regulation of the pH of the body's extracellular fluid (ECF). [1] The proper balance between the acids and bases (i.e. the pH) in the ECF is crucial for the normal physiology of the body—and for cellular metabolism. [1] The pH of the intracellular fluid and the extracellular fluid need to be ...
Energy homeostasis. In biology, energy homeostasis, or the homeostatic control of energy balance, is a biological process that involves the coordinated homeostatic regulation of food intake (energy inflow) and energy expenditure (energy outflow). [1][2][3] The human brain, particularly the hypothalamus, plays a central role in regulating energy ...
Homeostatic capacity refers to the capability of systems to self-stabilize in response to external forces or stressors, or more simply the capability of systems to maintain homeostasis. [ 1][ 2] For living organisms, it is life's foundational trait, consisting of a hierarchy and network of traits endowed by nature and shaped by natural selection.
After a few technical hiccups with short-circuits causing burn-outs, the homeostat was finally completed on 16 March 1948. [1] It was an adaptive ultrastable system, consisting of four interconnected Royal Air Force bomb control units [2] with inputs, feedback, and magnetically driven, water-filled potentiometers.
In neuroscience, homeostatic plasticity refers to the capacity of neurons to regulate their own excitability relative to network activity. The term homeostatic plasticity derives from two opposing concepts: 'homeostatic' (a product of the Greek words for 'same' and 'state' or 'condition') and plasticity (or 'change'), thus homeostatic plasticity means "staying the same through change".
Calcium metabolism. The body regulates calcium homeostasis with two pathways; one is signaled to turn on when blood calcium levels drop below normal and one is the pathway that is signaled to turn on when blood calcium levels are elevated. Calcium metabolism is the movement and regulation of calcium ions (Ca 2+) in (via the gut) and out (via ...
