Chapter 2 - Theories of Aging
(Eliopoulos: Gerontological Nursing,
Ninth Edition)
Growing old
the technique of developing vintage that starts at beginning
Nonstochastic theories
give an explanation for organic getting old as resulting from a complex, predetermined
method
stochastic theories
view the outcomes of biological growing old as as a consequence of random assaults from
each the inner and outside surroundings
Throughout records, there were numerous searches for a fountain of young people, the most
well-known being:
Ponce de León
This turned into thought to be an historic "existence extender"...
Extracts organized from tiger testicles
Cross-Linking Theory
Proposes that cell division is threatened as a result of radiation or a chemical response
wherein a cross-linking agent attaches itself to a DNA strand and prevents everyday parting
of the strands in the course of mitosis.
Loose radical idea
shows that growing old is due to oxidative metabolism and the results of loose radicals
Beta-Carotene and Vitamins C and E
antioxidants which could provide protection in opposition to unfastened radicals
Lipofuscin
, Granular pigment with no recognized function (age-pigment) a lipoprotein by-product of
oxidation that can be seen only underneath a fluorescent microscope, within the getting old
manner.
A negative relationship exists between an individual's age and the amount of lipofuscin
inside the body. True or False.
False. A superb dating exists among an man or woman’s age and the amount of lipofuscin
inside the body. Investigators have observed the presence of lipofuscin in other species in
amounts proportionate to the existence span of the species (e.G., an animal with one 10th
the lifestyles span of a individual accumulates lipofuscin at a price about 10 times greater
than human beings).
Put on and tear theories
characteristic growing old to the repeated use and injury of the frame over time as it plays its
surprisingly specialised functions.
Stresses to the body will have destructive consequences and cause situations including:
Select all that follow.
A. Gastric ulcers
b. Heart assaults
c. Thyroiditis
d. Hiatal hernia
e. Inflammatory dermatoses.
F. Migraines
a,b,c,e
Stresses to the body will have negative outcomes and result in conditions which include
gastric ulcers, heart assaults, thyroiditis, and inflammatory dermatoses.
Evolutionary Theories of Aging
associated with genetics and hypothesize that the differences inside the getting old system
and sturdiness of diverse species arise due to interplay between the approaches of mutation
and natural selection
mutation accumulation idea
indicates that aging takes place due to a declining force of natural selection with age. In
other phrases, genetic mutations that affect kids will ultimately be removed because the
victims will not have lived lengthy sufficient to breed and pass this to future generations.
Genetic mutations that seem past due in lifestyles, but, will acquire because the older
individuals they affect can have already passed these mutations to their offspring.
