The scientific study of aging and the problems associated with it, whether it is sociological, psychological, pathological, biophysical, etc.
An individual who studies the aging process on both older people and the social structure.
aging on the basis of years from birth
chronological aging
physical changes that reduce the efficiency of the organ system
biological aging
changes that occur in sensory and perceptual processes, mental functioning, adaptive capacity, and personality.
psychological aging
individual’s changing role and relationships in the social structure
social aging
A specialized part of the field of health care addressing the social, psychological and biophysical health aspects and problems of elderly persons.

Focused on how to prevent or manage the diseases of aging
Health care provider specializing in the care of elderly patients
process of gradual and spontaneous change resulting in maturation and then decline is called
what is programmed aging
something inside of us that controls the mechanisms of elderliness and deterioration
what is wear and tear aging
sum of the effects of environmental assaults
what is senescence
loss of cell dvision, growth, and fxn over time

degenerative processes of aging
changes attributed to aging itself
normal aging
complex of diseases and impairemnts that characterize the elderly
usual aging
deleterius effects are minimized, preserving function until senescence makes continued life impossible; remain fxn physically and mentally
successful aging
what 3 things occurs in normal aging
glucose intolerance
cognitive loss
tooth loss
what are diseases of elderly that look like normal aging
Heart Disease
what does the Haylick limit say
cells lose their ability to divide over time
what is inhibition
fibroblasts stop diving after a certain number of divisions
what is the ability to replicate based on
biological age
what happens to telomeres in cell division
shorten each time cell divides; stops dividing when become too short
mRNA promotes
increase in life span by acting as tumor supression gene

if mutated get uncontrolled cell division
name the types of cells that don not divide
cells that divide very little
cells that divide frequently and not affected by Hayflick limit
endothelial lining of intestinal tract
hayflick limits is based on
cellular and molecular aging
process due to physical or chemical insult which cause proteolysis and rupture of cell and its contents; cell can no longer transform external energy
a regulated process (genetics) by which cell commits suicide via fragmentation of DNA by deoxyribonuclease
apoptosis is seen in what diseases
name the 9 theories of aging
Free Radical
Cellular Garbage
Wear and Tear
Cross Linkage
Rate of living
Weak link
Error Catastrophe
Master Clock
theory that states that entropy producing agent slowly wears away at cell causing deleterious and irreversible damage
free radical theory
what are free radicals
by product of oxidation that has unpaired electron; highly reactive causing changes in membrane structure and chromosomes

oxidative damage increases overtime
role of glucose in senescence
promotes it thru nonenzymatic attachment to proteins and nucleic acids

causes glycation of proteins
reduces bgl
theory that states that a gradual accumulation of inert substances made in cell metabolism interfere with normal fxn cells causing displacement of cytolasmic contents
cellular garbabge theory
name the major cellular waste product
what does lipofusin do to promote aging
lots of cross links
lipofusin is what
brown yellow pigment
where in the eye is lipofusin seen
theory that states the aging is porgrammed in us and is controlled and cell death is inherent
aging by program theory
in the aging by program theory what is the structure that controls aging

decreases in fxn with age
what gland decreases in size w/ age
thymus gland
the aging by program theory states what about mRNA, tRNA, enzymes
made early in life and can not be replenished once used
theory that states that each person has a specific amount of metabolic energy available and the rate wat which this energy is used determines length of life

harmful byproducts accumulate
wear and tear theory
what does the wear and tear theory state in relation to caloric intake
decrease intake - increases life span in rats
theory that states that smaller animals have higher BMR and thus die earlier
rate of living theory
theory that states that a specific physilogical system is most vulnerable during senescence and when that system fails a cascade of effects accelerated the dysfxn of the entire organism
weak link theory
name 2 examples that are weak links
neuroedocrine system
immune system
theory that states that errors in DNA transcription or RNA translation lead to genetic errors that promote senescence
error catastrophe theory
theory that states that aging is under direct genetic control; survival of the fittest
master clock theory
young old
middle old
old old
>= 85
what has happened to the elderly population in the US btw 1900-2000
in the year 2011 when the baby boomers turn 65, what will happen to the elderly pop in the US
growth rate of elderly will be > than the total pop
which group has grown more rapidly than any other grouo and will be even greater in 2050
old old
probability estimate based on env conditions like dz and health care
life expectancy
max # yrs a given species could expect to live if env hazards are eliminated
max life expectancy
MLE for women
MLE influenced by what factors
medical tx
env toxins
