  2. Anatomical terms of location - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_location

    Central and peripheral refer to the distance towards and away from the centre of something. [33] That might be an organ, a region in the body, or an anatomical structure. For example, the central nervous system and the peripheral nervous systems. Central (from Latin centralis) describes something close to the centre. [33]

  3. Muscle weakness - Wikipedia

    en.wikipedia.org/wiki/Muscle_weakness

    Peripheral regulation therefore depends on the localized metabolic chemical conditions of the local muscle affected, whereas the central model of muscle fatigue is an integrated mechanism that works to preserve the integrity of the system by initiating muscle fatigue through muscle derecruitment, based on collective feedback from the periphery ...

  4. Central nervous system - Wikipedia

    en.wikipedia.org/wiki/Central_nervous_system

    The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.

  5. Peripheral vision - Wikipedia

    en.wikipedia.org/wiki/Peripheral_vision

    The distinctions between foveal (sometimes also called central) and peripheral vision are reflected in subtle physiological and anatomical differences in the visual cortex. Different visual areas contribute to the processing of visual information coming from different parts of the visual field, and a complex of visual areas located along the ...

  6. Neuropathic pain - Wikipedia

    en.wikipedia.org/wiki/Neuropathic_pain

    Central neuropathic pain is found in spinal cord injury [10] and multiple sclerosis. [11] Peripheral neuropathies are commonly caused by diabetes, metabolic disorders, herpes zoster infection, HIV-related neuropathies, nutritional deficiencies, toxins, remote manifestations of malignancies, immune mediated disorders and physical trauma to a ...

  7. Nervous system - Wikipedia

    en.wikipedia.org/wiki/Nervous_system

    A very important type of glial cell (oligodendrocytes in the central nervous system, and Schwann cells in the peripheral nervous system) generates layers of a fatty substance called myelin that wraps around axons and provides electrical insulation which allows them to transmit action potentials much more rapidly and efficiently. Recent findings ...

  8. Immune tolerance - Wikipedia

    en.wikipedia.org/wiki/Immune_tolerance

    Depending on the site of induction, tolerance is categorized as either central tolerance, occurring in the thymus and bone marrow, or peripheral tolerance, taking place in other tissues and lymph nodes. Although the mechanisms establishing central and peripheral tolerance differ, their outcomes are analogous, ensuring immune system modulation.

  9. Central chemoreceptor - Wikipedia

    en.wikipedia.org/wiki/Central_chemoreceptor

    Central chemoreception remains, in this way, distinct from peripheral chemoreceptors. The central chemoreception system has also been shown experimentally to respond to hypercapnic hypoxia (elevated CO 2, decreased O 2) and aqueous sodium cyanide injection into the whole animal [1] and in vitro slice preparation.
