  2. Physiology - Wikipedia

    en.wikipedia.org/wiki/Physiology

    Physiological state is the condition of normal function. In contrast, pathological state refers to abnormal conditions, including human diseases. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for exceptional scientific achievements in physiology related to the field of medicine.

  3. Homeostasis - Wikipedia

    en.wikipedia.org/wiki/Homeostasis

    An effector is the target acted on, to bring about the change back to the normal state. At the cellular level, effectors include nuclear receptors that bring about changes in gene expression through up-regulation or down-regulation and act in negative feedback mechanisms. An example of this is in the control of bile acids in the liver. [4]

  4. Life - Wikipedia

    en.wikipedia.org/wiki/Life

    Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from matter that does not. It is defined descriptively by the capacity for homeostasis, organisation, metabolism, growth, adaptation, response to stimuli, and reproduction.

  5. Allostasis - Wikipedia

    en.wikipedia.org/wiki/Allostasis

    The allostatic state represents the integrated totality of brain-body interactions. Health itself is an allostatic state of optimal anticipatory oscillation, hypothesized to relate to the state of criticality… Diseases are allostatic states of impaired anticipatory oscillations, demonstrated as rigidifications of set points across the brain ...

  6. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    In this state, the distinction between liquid and gas disappears. A supercritical fluid has the physical properties of a gas, but its high density confers solvent properties in some cases, which leads to useful applications. For example, supercritical carbon dioxide is used to extract caffeine in the manufacture of decaffeinated coffee. [3]

  7. Emergence - Wikipedia

    en.wikipedia.org/wiki/Emergence

    In terms of physical systems, weak emergence is a type of emergence in which the emergent property is amenable to computer simulation or similar forms of after-the-fact analysis (for example, the formation of a traffic jam, the structure of a flock of starlings in flight or a school of fish, or the formation of galaxies).

  8. Emotion - Wikipedia

    en.wikipedia.org/wiki/Emotion

    Expressing emotions through facial expressions, body language, and vocalizations helps convey information to others about one's internal state. This, in turn, facilitates cooperation, bonding, and the maintenance of social relationships. For example, a smile communicates happiness and friendliness, while a frown may signal distress or disapproval.

  9. Stress (biology) - Wikipedia

    en.wikipedia.org/wiki/Stress_(biology)

    For example, studies have found that caregivers, particularly those of dementia patients, have higher levels of depression and slightly worse physical health than non-caregivers. [ 14 ] When humans are under chronic stress, permanent changes in their physiological, emotional, and behavioral responses may occur. [ 15 ]
