  2. Hypothalamic–pituitary–thyroid axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    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.

  3. Energy homeostasis - Wikipedia

    en.wikipedia.org/wiki/Energy_homeostasis

    Energy intake is measured by the amount of calories consumed from food and fluids. [1] Energy intake is modulated by hunger, which is primarily regulated by the hypothalamus, [1] and choice, which is determined by the sets of brain structures that are responsible for stimulus control (i.e., operant conditioning and classical conditioning) and cognitive control of eating behavior.

  4. Central governor - Wikipedia

    en.wikipedia.org/wiki/Central_governor

    This hypothesis was disregarded and further research upon exercise fatigue was modeled in terms of it being due to a mechanical failure of the exercising muscles ("peripheral muscle fatigue"). This failure was caused either by an inadequate oxygen supply to the exercising muscles, lactic acid buildup, or total energy depletion in the exhausted ...

  5. Central nervous system fatigue - Wikipedia

    en.wikipedia.org/wiki/Central_Nervous_System_Fatigue

    Central nervous system fatigue, or central fatigue, is a form of fatigue that is associated with changes in the synaptic concentration of neurotransmitters within the central nervous system (CNS; including the brain and spinal cord) which affects exercise performance and muscle function and cannot be explained by peripheral factors that affect muscle function.

  6. Homeostatic feeling - Wikipedia

    en.wikipedia.org/wiki/Homeostatic_feeling

    emotional affect: e.g., anger, fear. [4] Some homeostatic feelings motivate specific behavior aimed at maintaining the body in its ideal state. For example, hunger motivates eating, fatigue motivates resting and hyperthermia motivates stepping into the shade. [5] [6] [7] Sheep respond to hunger, fatigue and hyperthermia by grazing and resting ...

  7. Homeostatic capacity - Wikipedia

    en.wikipedia.org/wiki/Homeostatic_capacity

    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.

  8. Homeostasis - Wikipedia

    en.wikipedia.org/wiki/Homeostasis

    Thus, to Barcroft homeostasis was not only organized by the brain—homeostasis served the brain. [13] Homeostasis is an almost exclusively biological term, referring to the concepts described by Bernard and Cannon, concerning the constancy of the internal environment in which the cells of the body live and survive.

  9. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.
