EXAM Flashcards
Periods of parental developement and their characteristics?
Germinal 1-2 weeks: Implantation of blastocyte (Developement of ambilical cord and placenta)
Embryonic 3-8 Weeks: Central nervous system, internal organs, muscles, and skeletan begin to form
Foetal Week 9 to end broken into Three Sections:
- First trimester: organs, muscles, ect - Second: Mother can feel movement, synapses form rapidly - Third: reaches viability, extensive body growth
Three types of medical interventions of pregnancy?
Analgesic (e.g., epidural) to relieve pain and
help a mother relax. Tends to weaken
contraction and prolongs labour. Exposed
newborns tend to have lower Apgar scores.
Instrument delivery (forceps, suction cup). Used when the mother’s pushing does not move the baby through the birth canal.
Induced labour is started artificially by
breaking the water amnion and providing a
synthetic hormone that stimulates
contractions. May be chosen when well-being of
mother or baby is threatened with continued
pregnancy.
What is anoxia?
Oxygen deprivation at birth
What is considered a premature baby?
Preterm infants are babies born before 35 weeks of
pregnancy. small-for-date infants are babies born below their expected weight given the length of the pregnancy.
What is infant mortality and what is a precurser in this?
Infant mortality: the number of deaths
in the first year of life per 1000 lives
births.
Two leading factors for death of newborns are serious physical defects and low birth weight. The former does not differ much across ethnicity or income levels, but the latter does. Low birth weight is associated with poverty and weak health care system.
Infant mortality tends to be higher in
developing societies, where fertility rate
is also high. Infant mortality has been
declining in many societies.
What is the apgar scale?
Apgar score is a method to quickly summarize the health of newborn children
Score of 7 or better: good condition
Score between 4 and 6: baby needs assistance
Score of 3 or lower: baby is in serious danger and needs medical attention
What is postnatal depression?
Severe or prolonged symptoms of depression (clinical depression) that last more than 1 week or 2, and interfere with the ability to function on a daily basis with normal routines including caring for a baby
What is the rooting reflex?
: when cheek near corner of mouth is stroked, baby turns head toward source of stimulation.
Disappears after about 3 weeks. Helps a breastfed baby find the mother’s nipple.
What is the moro reflex?
Stimulation: sudden loss of support on back or loud
noise
Response: back arch, arm extended outward and inward toward the body. -Age of Disappearance: 6 months -Function: may have helped infant cling to mother.
What is the The Babinski reflex?
- Stimulation: stroke sole of foot from toe toward heel
- Response: toes fan out and curl as foot twists in.
- Age of Disappearance: 6-12 months
- Function: unknown
Two main factors of physical growth?
Heredity: when diet and health are adequate, height and rate of physical growth are largely determined by heredity.
Nutrition. Breast milk is an ideal source of nutrition. WHO recommends breastfeeding until age 2 with solid food added at 6 months.
What is Experience-expectant brain growth?
Depends on ordinary experiences “expected” by brain
for normal growth
Occurs early and naturally
what is Experience-dependent brain growth?
Results from specific learning experiences
Varies widely across individuals and cultures
Rushing early learning overwhelms the brain’s neural
circuits.
Fine motor developement?
Newborns: bring their hands into their field of vision. Also, show uncoordinated swipes (prereaching) that rarely contact the object. These behaviours suggest that babies are biologically prepared to coordinate hand with eyes in the act of exploring. 3-4 months: reaching appears more purposeful and accurate. Grasp reflex replaced by the ulnar grasp. 4-5 months: with infants beginning to sit up, hands become coordinated in exploring objects. ~1 year: use the thumb and index finger to manipulate objects (pincer grasp
Stages of developement vision?
Focus: 2 months
Color Vision: 4 months
Visual Acuity: 4 year
Tracking objects: 6 months
