Early development and preterm birth Flashcards
(14 cards)
what are the 3 stages of early development
germinal stage - 0-2w
embryonic stage - 3-8w
foetal stage - 9-40w
what are the main occurrences in the germinal stage
cell division
zygote (fertilsed egg) formation through conception
zygote turns into a blastocyst
blastocyst implants into the uterus
what are the main occurrences in the embryonic stage
bones develop
organs develop
brain matures for muscle movement
what are the main occurrences in the foetal stage
continued development
neuronal development
what are some reflexes
crying, sucking, grasping
what are the 2 perspectives on reflexes
traditional - evolutionary value
recent - disappear after birth
who found that 1w olds have a visual preference for patterns
Fantz 1975
what are preterm births
before 38w
low birth weight unless diabetic
what are some factors affecting preterm birth
previous
illness
drugs
age of mother
stress
why has the survival rate increased for preterm births
improved antenatal care
improved care units
equipment
drugs - prepare lungs
who found that preterm babies were less secure
ruiz 2018
who found that preterm babies have delayed language due to no background noise in hospital
Zambrana 2015
who found that preterm babies have delayed pragmatic and lexical development
Guarini 2016
how can we help the development of preterm babies
skin to skin contact
reading and interacting
