Developmental homeostasis is a process in which animals develop more or less normally, despite defective genes and deficient environments. [1] It is an organism's ability to overcome certain circumstances in order to develop normally. This can be a circumstance that interferes with either a physical or mental trait.
Short overview of thyroid homeostasis. [1]The hypothalamic–pituitary–thyroid axis (HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress.
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.
A thermostat operates by switching heaters or air-conditioners on and off in response to the output of a temperature sensor. Cruise control adjusts a car's throttle in response to changes in speed. [87] [88] An autopilot operates the steering controls of an aircraft or ship in response to deviation from a pre-set compass bearing or route. [89]
Autoregulation is a process within many biological systems, resulting from an internal adaptive mechanism that works to adjust (or mitigate) that system's response to stimuli. While most systems of the body show some degree of autoregulation, it is most clearly observed in the kidney , the heart , and the brain . [ 1 ]
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
Shivering (also called shuddering) is a bodily function in response to cold and extreme fear in warm-blooded animals. When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy.
In psychology, a drive theory, theory of drives or drive doctrine [1] is a theory that attempts to analyze, classify or define the psychological drives. A drive is an instinctual need that has the power of driving the behavior of an individual; [2] an "excitatory state produced by a homeostatic disturbance".
