Drugs: alcohol, FAS (video), nicotine, cocaine, thalidomide.Infectious diseases: rubella, syphilis (know specific effects at specific times), HIV.Environmental hazards: radiation (video). Low-birth weight infants (p. 12-123), folic acid. APGAR (Table 4.7 and text, p. 122-123). What is surfactant (p. 123)? A substance that prevents the air sacs of the lungs from sticking together and therefore aids breathingWhat are the maternal & fraternal ages most associated with miscarriage (see p.113 underFather’s State)? Women 35+, men 40-50What are some delivery complications - anoxia, medications, etc. (p. 116-117)? Anoxia – poor oxygenSedatives going through to make the baby sluggish Trauma through forceps or suction to aid delivery or overall prolonged laborBreech or other odd presentation (emergency cesarean) What is kangaroo care (p. 123-125)? Having baby skin-to-skin (usually on the chest) helps maintain body temperature, heart rate, and oxygen levels in the blood.Chapter 5: Nervous system development / Motor developmentLateralization -specializations of each hemisphere, what is the corpus callosum, plasticity (re-wiring, Sharon video), know results of Rosenzweig’s and Greenough’s experiments. Neuron proliferation, migration, aggregation/organization and differentiation (p. 96-97) ,
which process is most affected by alcohol . . .by radiation? Know about synaptogenesis & myelination. Nervous system development: neural plate (16 days), neural tube, neural crest cells (become the PNS), CNS (developed at 25 days), PNS (peripheral nervous system, developed from neural crest cells). Anencephaly (failure of anterior tube closure, fatal), spina bifida (failure of posterior tube closure). What happens in the nervous system during the third trimester & first 1-2 yrs. of life? Proliferationmake new neurons50,00-100,000 per second, p. 96 weaaks 6-17Migrationarea of brain and layer, development is inside to outside8-15wks (p. 97)Aggregation(organize) like goes with like (those with like function group together)Differentiation Specialize structurally and functionallyWhich neurotransmitter will neuron produce What type of glial cell? SynaptogenesisForming functional connectionIncreases rapidly after birth Young children have more synapses than adults Myelination Sheath formed in neurons in fetal period (third trimester, mo 7/8/9)continues throughout early adulthood 1-2 yrsincrease in size, number of synaptic connections myelination continues development of PFC prefrotal cortex Pruning decrease in the number of connections and number of neuronsuse it or lose it Know height & weight changes across the lifespan.
In adolescence, increase in dopamine neurotransmitter due to hormonal influence
