life span exam 1 Flashcards
How much brain weight is Loss at ages 20through40
5% to 10% of weight
Lifespan defined
Maximum number of years and individual can live
Life expectancy
Number of years average person will prob live
synapsing pruning
un-used connections are deactivatedI
Rental cortex is responsible for
reasoning/ self control
amygdala hels control
emotions /anger
Cardio vascular System causes what in the elderly
Cholesterol begins to accumulate on artery walls, blood pressure increases, and decreased in lung capacity
Give example of gene length abnormalities
Diabetes and hemophilia
Prenatal development order
germinal period (implantation,blastocye develops into embryo,22% of zygote fail to implant)
Embryonic(organ formation, 31% results in miscarriage)
& fetal(2 moth after conception until birth, stillborn ratio 1:160)
What happens during the germinal period
cell division, Attachment of zygote to uterine wall(10-14days)
Embryos support system includes
Amnion umbilical cord placenta
What a teratogen & example
Agent that causes birthdefects /negative altercations
Example: drugs environment pollution incompatible blood
mother has Rh- father has Rh+ Whats the result!
Rh+ fetus, moms immune system will attack baby =miscarriage
what’s included in a new born assessment
Apgar scale, 1-5min after birth
includes heart rate, respiration, reflex, body color, muscle mass
define plasticity
the ability to change / adapt
3 kinds of influences
Normative age-graded
Normative history graded
Non normative life graded
define and give example of SES
Social Economical Status
Economics, social or persona status, education
Give example of each: Biological age psychological age sociological age chronological age
Biological age: health related, how well your organisms are taken care of(nutrition/exercise)
psychological age: level of maturity
sociological age: social rules implanted by society( when to retire, get married, buy house , go to college..)
chronological age : actual age from birth
Define cognitive process
change in individuals thoughts and language
Define socio emotional
change in personality based on relationship w/ plp
example of evolutionary psychology
weight gain/ loss depending on what’s best for survival, speed
nature vs nurture
nature: biological, genes, inheritance
nurture: environment, exposure
what’s Cephalocaudal
growth of head first
what occurs during proximal pattern
growth starts at torso(center)
what’s the average weight and height of infant
7.5lb, 20in
what’s puberty
rapid physical maturation involving hormonal & bodily changes
what determines puberty
endocrine system, weight, body fat, leptin hormone
what’s amemorhea
absence / suppression of mensuration
example anorexia,under nourishment, can delay puberty
what occurs in the cardiovascular system when aging?
cholesterol begins to accumulate on artery wall, blood pressure increase, decrease in lung capacity.
Who proposed natural selection
Darwin
what’s the evolution theory
the adaptive behavior is behavior that promotes survival rate
genes are passed on to new cells when
they go under mitosis/meiosis
its a way of reproduction/ replication of cells
egg+sperm=
zygote
sex chromosomal abnormalities produce what kind of syndromes?
down syndrome(extra 21) , XYY, Klinefelter, turner
teratogens include(3)
dosage ( the amount taken) Genetic susceptibility(incompatible blood) Timing of exposure (within one month of birth)
Example of:
Normative age graded
Normative History graded
Non Normative life event
Normative age graded: something that a same age group goes though (menopause, retire, go to college, puberty)
Normative History graded (historical event a certain generation goes through, civil war, WW1,WW11)
Non Normative life event (something that w has only occurred to one person)
genetic foundation of development includes
nucleus, chromosome, gene
Passive heredity
child inherit tendencies from parents
parents who have histories of antisocial behaviour (which is moderately heritable) are at increased risk of abusing their children
Evocative heredity
environmental tendencies
arguing with a spouse may result in someone becoming depressed, it is equally plausible that individuals who are prone to depression tend to provoke arguments
active heredity
supports kids interest, For example, individuals who are characteristically extroverted may seek out very different social environments than those who are shy and withdrawn.
fraternal twins
dizygotic, separate sperm and egg
Identical twin
monozygotic, single zygote, split into 2
genotype
is the genetic make up
phenotype is
the physical appearance
recessive
is the hidden gene that experts its self when both parents have a recessive gene
Whats an amnion
a yolk sac that helps protect the embryo
What does the umbilical cord do
it connects the moon to the embryo and delivers nutrition and removes waste
The placenta does what
its a temporary organ that allows the blood vessels of the fetus and mom intertwined wit each other not CONNECTED
During what month can a fetus survive out side of womb
7 months w/ support
paternal factors
male exposure to lead, radiation,pesticides
Environmental factors for fetus
exposed mom to radiation, carbon monoxide, lead
Whats preterm
born prior to 38wks
