 [make a copy] See also Engagement 4.1  Understanding the Effects of Teratogens (p. 114).    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 breathing   What are the maternal & fraternal ages most associated with miscarriage (see p.113 under Father s State)?  Women 35+, men 40-50 What are some delivery complications - anoxia, medications, etc. (p. 116-117)?  Anoxia – poor oxygen Sedatives going through to make the baby sluggish  Trauma through forceps or suction to aid delivery or overall prolonged labor Breech 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 development Lateralization -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? Proliferation make new neurons 50,00-100,000 per second, p. 96 weaaks 6-17 Migration area of brain and layer, development is inside to outside 8-15wks (p. 97) Aggregation (organize) like goes with like (those with like function group together) Differentiation Specialize structurally and functionally Which neurotransmitter will neuron produce What type of glial cell? Synaptogenesis Forming functional connection Increases 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 yrs increase in size, number of synaptic connections myelination continues development of PFC prefrotal cortex Pruning decrease in the number of connections and number of neurons use it or lose it Know height & weight changes across the lifespan.
