Birth And Physical Development Flashcards
When does prenatal development begin
What is prenatal development
This development takes an average of how many weeks and these weeks consists of which stages
Which period does organogenesis occur ?
When does the second period start and when does it last?
At which period do most women realize they’re pregnant ?
Which period is the longest and when does it begin and end?
When do the body systems begin to work
During prenatal development what can influence genes to stop working or make them weaker
It begins When a sperm successfully fertilizes an egg,the many changes that transform the fertilized egg into a newborn human is prenatal development
Average is 38 weeks but it’s from 37-42 weeks
The weeks consists of the period of the zygote,period of the embryo and period of the foetus
Period of the embryo (that’s why women at this stage should take folic acid for organ development especially for the spine development to prevent spina bifida and other congenital abnormalities)
Starts 3rd week after conception and lasts until the end of the 8th week .
Period of the embryo
Period of the foetus
It’s the final and longest phase . Begins at the ninth week (when cartilage begins to turn to bone) and ends at births
Period of the foetus
Toxins,nutrition,stress
What observations are Made during prenatal development
What things influence prenatal development
Copulation Fertilization Implantation Organogenesis Multiple pregnancies Infertility
Nutrition-proteins vitamins minerals example folic acid and iron
Stress-leads to
Low birth weight in women w anxieties
Age of pregnant woman(extremes of age such as too old or too young can cause them to have problems ,congenital abnormalities can occur in older women who get pregnant)
Lifestyle factors:smoking (due to effect of nicotine leading to increased risk of abortion , baby may be small for the gestational age(SGA)
Alcohol intake can cause fetal alcohol syndrome
STIs
Teratogens example thalidomide ,chemotherapy drugs cause malformations and may lead to miscarriage ,antiepileptic drugs (phenytoin) increase the incidence of cleft lip and palate ,restricted growth,aspirin(deficits in intelligence),caffeine(low birth weight),nicotine(retarded growth)
Environmental hazards (nuclear bombs,chemical wastes,radiation,pollution)
Diseases both inherited and non inherited
Example: HIV/AIDS,rubella,cytomegalovirus,syphilis,diabetes)
What is the upper portion of the vagina called?
What is the part of the Fallopian tube that inserts into the womb
What are fimbrae
What are the parts of the Fallopian tube from the part that takes the egg to the part that connects to the womb
Ectopic pregnancy can be confused with what on scan?
Vault
intramural, or uterine
Fimbrae are hairlike structures that pick the egg
Fimbrae-infundibulum-ampulla-isthmus-intramural
Hemorrhagic cyst.
Pregnancy can be there with the hemorrhagic cyst instead of the ectopic and the bleeding may be due to the cyst and not the ectopic
So be very careful when diagnosing ectopic
What are the conceptions of age?
Define them
What are the stages of physical growth and give the ages)
Which physical stage is more rapid
Chronological age- number of years that have gone by since birth
Social age: social roles and expectations related to a persons age
Biological age:deterioration of organisms that leads inevitably to their death
Psychological age: it’s subjective. It’s the individuals adaptive capacities compared w those of other individuals of the same chronological age
Infancy- growth is more rapid
-growth required high mount of energy
(First 2 years of life (the first month is the neonatal or newborn period))
Early childhood(2 to 5 or 6 years (some prefer to describe as toddlers children who have begun to walk and are age 1 to 3))
Middle (
6 to about 12 (or until the onset of puberty) )and late childhood
Adolescence (Approximately 12 to 20 )
Early adulthood-20 to 40 years
Middle adulthood-40 to 65 years
Late adulthood-
65 years and older
What’s the composition of breast milk
What are the benefits of breast milk
It’s rich in protein, sugar, vitamins and minerals, plus numerous bioactive components – such as hormones, growth factors, enzymes and live cells – to support your baby’s healthy growth and development.
Advantages:
It boosts baby’s immune system.
It balances baby’s belly.
Breastmilk plants good bacteria into the digestive system to build a strong, healthy baby
Breastmilk is easily digestible.
Mother’s milk is perfect for baby’s developing digestive tract.
Name one domain of development and explain
Cognitive development focuses on a child’s development in terms of what things?
What theory is associated w cognitive development?
Cognitive development
Refers to how a person perceives ,thinks,and gains understanding of his or her world through the interaction of genetic and learned factors
Information processing Conceptual resources Perceptual skill Language learning Other aspects of the developed adult brain
Jean Piaget’s theory
What are the theories of cognitive and psychoanalytic development
Piaget’s theory also called theory of constructivism
Sigmund Freud Psychoanalytic theory
What does Piaget’s theory say?
Children actively construct new understandings of the world based on their own experiences
Humans do not acquire knowledge and understanding by passively perceiving it within a direct process of knowledge transmission,rather they contstruct new understandings and knowledge through experience and social discourse integrating new information with what they already know
Example: it is common for pre school kids to invent their own ideas by saying the sun is alive because it moves in the sky
How do kids construct accurate understandings of the world?
According to Piaget,kids understand the world with schemes. What are schemes?
By being: Curious Active explorers Watching what is going on around them Seeing what happens when they experiment on objects they encounter
Psychological structures that organize experience. They are mental categories of related events,objects and knowledge
What are the four major periods of cognitive development
These stages form what Piaget called?
Sensorimotor stage(birth to age 2)
Preoperational stage (2-7 years)
Concrete operations stage(ages 7-11)
Formal operations stage(11-12 or older)
An invariant sequence ;all children progress through the stages in the order they are listed without skipping stages or regressing to earlier stages
The ages are only guidelines cuz different kids progress at different rates
What is the sensorimotor stage?
What is object permanence?
How is object permanence seen?
What their senses tell them is what their motor does
Infants in this stage deal with the world directly through their (perceptions) and actions(motor skills)
They construct an understanding of the world by coordinating sensory experiences (such as seeing and hearing) with physical,motor actions
Object permanence is the understanding that objects continue to exist even when they can’t be seen,heard or touched
By watching an infants reaction when an interesting object disappears. If the infant searches for the object,it’s assumed the infant believes it’s still there or it continues it exist
What is the preoperational stage
Child has now developed the capacity for symbolic thought but isn’t yet capable of logical problem solving
According to Piaget,pre school children are egocentric thinkers who have difficulty adopting perspectives other than their own and they may cling to incorrect ideas simply because they want them to be true
The 4- or 5-year-old can use words as symbols to talk about a problem and can mentally imagine doing something before actually doing it.
Preschoolers use their capacity for symbolic thought to develop language, engage in pretend play, and solve problems. But their thinking is not yet logical; they are egocentric (unable to take others’ perspectives) and are easily fooled by perceptions, failing conservation problems because they cannot rely on logical operations.
What are concrete operations
School-age children acquire concrete logical operations that allow them to mentally classify, add, and otherwise act on concrete objects in their heads. They can solve practical, real-world problems through a trial-and-error approach but have difficulty with hypothetical and abstract problems.
They are more logical at this stage
They do well on problems that allow them to think about concrete objects
They can perform many logical actions in their head on concrete objects
For example they can mentally categorize or add or subtract objects
What are the characteristics of the preoperational stage
Egocentrism: Arises from egocentrism. Thinks that nothing changes. Thinks that nothing can be undone. A thing cannot be restored to the way it was before a change occurred
Symbolic representation
Which characteristic of preoperational thought involves a child assuming that the world is unchanging, so always remains just the way it is currently? A young child’s belief that natural objects are alive and animals have human characteristics is: static reasoning or conservation (Conservation is the understanding that something stays the same in quantity even though its appearance changes.)
Centration and conservation: Centration is the tendency to focus on only one aspect of a situation at one time. while ignoring all other properties or characteristics
Actually it’s:
Egocentrism-child believes everyone sees the world as he or she does
Example:
A child gestures during a telephone conversation not realizing that the listener can’t see the gestures
Centration:child focuses on one aspect of a problem or a situation but ignored other relevant aspects
Example:In conservation of liquid quantity the child pays attention to the height of the liquid in the beaker but ignores the diameter of the beaker
Appearance as reality: Child assumes that an object really is what it appears to be
Example: child believes that a person smiling at another person is really happy even though the other person is being mean
What is the formal operations stage
Adolescents can think about abstract concepts and purely hypothetical possibilities and can trace
the long-range consequences of possible actions. With age and experience, they can form hypotheses and systematically test them using the scientific method.
Adolescents who reach the formal operations stage are able to think more abstractly and hypothetically than school-age chil- dren. They can define justice abstractly, in terms of fairness, rather than concretely, in terms of the cop on the corner or the judge in the courtroom. They can formulate hypotheses or pre- dictions in their heads, plan how to systematically test their ideas experimentally, and imagine the consequences of their tests. It often takes some years before adolescents can adopt a thoroughly systematic and scientific method of solving problems and can think logically about the implications of purely hypothetical ideas.
