  2. Hyperthermia - Wikipedia

    en.wikipedia.org/wiki/Hyperthermia

    Hyperthermia is generally diagnosed by the combination of unexpectedly high body temperature and a history that supports hyperthermia instead of a fever. [2] Most commonly this means that the elevated temperature has occurred in a hot, humid environment (heat stroke) or in someone taking a drug for which hyperthermia is a known side effect ...

  3. Endotherm - Wikipedia

    en.wikipedia.org/wiki/Endotherm

    The resting human body generates about two-thirds of its heat through metabolism in internal organs in the thorax and abdomen, as well as in the brain. The brain generates about 16% of the total heat produced by the body. [8] Heat loss is a major threat to smaller creatures, as they have a larger ratio of surface area to volume.

  4. Fever - Wikipedia

    en.wikipedia.org/wiki/Fever

    A pyrogen is a substance that induces fever. [89] In the presence of an infectious agent, such as bacteria, viruses, viroids, etc., the immune response of the body is to inhibit their growth and eliminate them. The most common pyrogens are endotoxins, which are lipopolysaccharides (LPS) produced by Gram-negative bacteria such as E. coli.

  5. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.

  6. List of enzymes - Wikipedia

    en.wikipedia.org/wiki/List_of_enzymes

    Function: Amylase is an enzyme that is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates to be turned into simple sugars that will be easier to absorb. Clinical Significance: Amylase also has medical history in the use of Pancreatic Enzyme Replacement Therapy (PERT). One of the components is ...

  7. Thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Thermoregulation

    Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.

  8. Heat stroke - Wikipedia

    en.wikipedia.org/wiki/Heat_stroke

    Substances that inhibit cooling and cause dehydration such as alcohol, stimulants, medications, and age-related physiological changes predispose to so-called "classic" or non-exertional heat stroke (NEHS), most often in elderly and infirm individuals in summer situations with insufficient ventilation.

  9. Histamine N-methyltransferase - Wikipedia

    en.wikipedia.org/wiki/Histamine_N-methyltransferase

    Histamine N-methyltransferase is encoded by a single gene, called HNMT, which has been mapped to chromosome 2 in humans. [5]Three transcript variants have been identified for this gene in humans, which produce different protein isoforms [6] [5] due to alternative splicing, which allows a single gene to code for multiple proteins by including or excluding particular exons of a gene in the final ...
