AAMC Fl 2 P/S Flashcards
iris
the coloured part of the eye
composed of the constrictor and dilator pupillae
lens (eye)
lies right behind the iris
focuses the light onto the retina
vitreous
the gel like substance within the eye
retina
at the back of the eye
contains rods and cones
converts photons of light to electrical signals
cones (eye)
used for colour vision and sense fine detail
rods (eyes)
only sense light and dark (good for low light conditions)
low sensitivity to details and do not sense colour
fovea (eye)
has a high concentration of cones (no rods)
visual acuity is best at the fovea
pathophysiology of Alzheimer’s (3)
build-up of beta-amyloid plaques (extracellular)
neurofibrillary tangles (intracellular)
hyperphosphorylation of tau proteins
which type of memory deteriorates first in AD?
episodic memories formed later in life are forgotten first (they have less time to consolidate)
semantic memories are more impaired than procedural memory
dependency ratio
an age-based measurement takes people <14 and >65 who are not in the labour force, and compares that to # of people who are
Higher the ratio, more dependent people there are.
Life Course Theory
Age Stratification Theory
social capital
the networks of relationships among people who live and work in a particular society, enabling that society to function effectively
cultural capital
knowledge, education, and skills transmitted across generations
what is the “silent generation”
the group of people born during the great depression (lower fertility rates at this time?)
older than the baby boomers
Intersectionality
discrimination based on multiple factors
Social Stratification
a society’s categorization of its people into groups based on socioeconomic factors like wealth, income, race, education, etc.
meritocracy
a society where advancement up the social ladder is based on their own ability and achievements; everyone has equal opportunity (birth/parental background doesn’t matter)
plutocracy
a society that is ruled or controlled by people of great wealth or income
absolute poverty vs relative poverty
absolute poverty → threatens survival (same no matter where you are in the world)
relative poverty → a % level below the median income of the country (will change depending on where you are in the world)
marginal vs structural poverty
marginal poverty → when an individual can’t find/keep a job
structural poverty → people are poor because of how society is structured rather than individual reasons
primary group vs secondary group
primary group → closest members of the group to you, ex. in a wedding the bridesmaids/groomsmen
secondary groups → formal and business-like relationships; based on a limited purpose/goal; usually short term
impression management
a conscious or subconscious process in which people attempt to influence the perceptions of other people about a person, object or event by regulating and controlling information in social interaction
front stage vs back stage self
front stage → when people are in a social setting Ex. someone watches baseball with friends even if he doesn’t like baseball. Manipulating how he’s seen to make friends.
Back stage – more private area of our lives, when act is over. You can be yourself.
