Exam 3: Theories of Aging

The stochastic theories of aging are founded on a programmed perspective that is related to genetics or one's biological clock.

There is decreased immune function in the elderly due to altered lymphocyte function, decreased cell-mediated and humoral immune response, and what gland shrinking to 15% of its capacity?

As women grow older, which of the following becomes the major source of estrogen?

Because a free radical molecule is unpaired, it is able to enter reactions with other membranes, especially along membranes and with nucleic acids.

Selective optimization with compensation is one example of a theory that emerged from the Stages of Personality Development Theory.

What theory highlighted the importance of cohorts and the associated socioeconomic and political impact on how individuals age?

What pigment, commonly referred to as the age pigment, is considered to be a threat to multiple cellular systems including the ubiquitin/proteasome pathway, which leads to cellular death?

Borrowing from what branch of social science, Havighurst and colleagues created Continuity Theory, which hypothesizes that personality influences the roles we choose and how we enact them?

What theory proposes that aging would not occur if destructive factors such as radiation did not exist and cause mutations and regulatory disorders?

What theory states that people tend to view life through either their own "lens" (introverts) or the lens of others (extroverts)?

Melatonin, considered to be the hormone linked to sleep and wake cycles because there are large numbers of melatonin receptors in the suprachiasmatic nucleus, is secreted by what gland?

What enzyme, also called the "cellular fountain of youth," allows human cells grown in the laboratory to continue to replicate long past the time they normally stop dividing?

What theory assumes that quality of life, functional capacity, and dependency are connected and that positive consequences are possible despite age-related limitations?

What theory borrows from disengagement theory but does not accept its idea that social disengagement is a necessary and natural development?

Older adults are more vulnerable to free radical damage because free radicals are attracted to cells that have transient or interrupted perfusion.

What theory proposes that aging would not occur if destructive factors such as radiation did not exist and cause mutations and regulatory disorders?

Gerotranscendence borrows from disengagement theory but does not accept its idea that social disengagement is a necessary and natural development.

What theory has been described as "the only aging theory to have stood the test of time"?

It is thought that people who limit calories, fat, and specific proteins in their diet may increase the formation of free radicals.
