  2. Regeneration (biology) - Wikipedia

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

    While reparative regeneration is a rare phenomenon in mammals, it does occur. A well-documented example is regeneration of the digit tip distal to the nail bed. [ 83 ] Reparative regeneration has also been observed in rabbits, pikas and African spiny mice.

  3. Regeneration in humans - Wikipedia

    en.wikipedia.org/wiki/Regeneration_in_humans

    Regeneration in humans is the regrowth of lost tissues or organs in response to injury. ... regeneration generally occurs before scarring. [8] In 2008, ...

  4. Neuroregeneration - Wikipedia

    en.wikipedia.org/wiki/Neuroregeneration

    Guillain–Barré syndrome – nerve damage. Neuroregeneration in the peripheral nervous system (PNS) occurs to a significant degree. [5] [6] After an injury to the axon, peripheral neurons activate a variety of signaling pathways which turn on pro-growth genes, leading to reformation of a functional growth cone and regeneration.

  5. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    There are three phases to the light-independent reactions, collectively called the Calvin cycle: carboxylation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Though it is also called the "dark reaction", the Calvin cycle does not occur in the dark or during nighttime.

  6. Wallerian degeneration - Wikipedia

    en.wikipedia.org/wiki/Wallerian_degeneration

    Wallerian degeneration occurs after axonal injury in both the peripheral nervous system (PNS) and central nervous system (CNS). It occurs in the section of the axon distal to the site of injury and usually begins within 24–36 hours of a lesion. Prior to degeneration, the distal section of the axon tends to remain electrically excitable.

  7. Bone remodeling period - Wikipedia

    en.wikipedia.org/wiki/Bone_remodeling_period

    Each vertebrate species exhibits a distinct duration of bone regeneration and remodeling, and it appears as though there is an inversely proportional relationship between the rate of bone regeneration and the phylogenetic evolution of the animal. [7] Each remodeling period lasts 3–6 months in humans, 3 months in dogs, and 6 weeks in rabbits. [8]

  8. Healing - Wikipedia

    en.wikipedia.org/wiki/Healing

    Acute tubular necrosis (ATN) in the kidney is a case in which cells heal completely by regeneration. ATN occurs when the epithelial cells that line the kidney are destroyed by either a lack of oxygen (such as in hypovolemic shock, when blood supply to the kidneys is dramatically reduced), or by toxins (such as some antibiotics, heavy metals or carbon tetrachloride).

  9. Epimorphosis - Wikipedia

    en.wikipedia.org/wiki/Epimorphosis

    During regeneration, only cartilage cells can form new cartilage tissue, only muscle cells can form new muscle tissue, and so on. The dedifferentiated cells still retain their original specification. [12] To begin the physical formation of a new limb, regeneration occurs in a distal to proximal sequence. [17]
