24
Q

Teratogen

Study These Flashcards
A

A teratogen is something that can cause birth defects or abnormalities in a developing embryo or fetus upon exposure.

25
Epigenisis
The emergence of new structures and functions in the course of development
26
Gametes
reproductive cells, egg and sperm, contain half genetic material
27
Zygote
fertilized egg
28
Embryonic stem cells
embryonic cells that can develop into any type of body cell
29
Androgens
A class of hormones that include testosterone, leads to male genetalia
30
Identical (monozygotic) twins
twins, split half zygote, zelfde genen
31
Faternal (dizygotic) twins
twins, two eggs fertilized, half of genes each
32
Neural tube
a groove formed in the top layer of differentiated cells in the embryo that eventually becomes the brain and spinal coard
33
Amniotic sac
a transparent, fluid filled membrane that surrounds and protects the fetus
34
Placenta
A support organ for the fetus, circulatory system between mother and child, semipermeable membrane --> exchange materials (zuurstof, nutriens, co2 en afval stoffen)
35
Umbilical cord
A tube containing the blood vessels connecting the fetus and placenta
36
Cephalocaudal development
Dingen rond het hoofd ontwikkelen eerder dan de rest
37
Phylogenetic continuity
Mensen delen bepaalde karakteristieken , gedrag en developmental processes with non-human animals, especially mammals
38
Habituation
a simple form of learning that involves a decrease in response to repeated or continued stimulation
39
Dishabituation
The introduction of a new stimulus rekindles interest following habitation to a repeated stimulus
40
sensitive period
the period of time during which a developing organism is most sensitive to the effects of external factors
41
dose-response relation
The greater the fetus exposure to a potential teratogen, the more likely the fetus will suffer damage
42
sudden infant death syndrome (SIDS)
sudden, unexpected death of an infant less than 1 year old that has no identifiable cause.
43
fetal alcohol spectrum disorder (FASD)
the Harmful effects of maternal alcohol consumption on a developing fetus.
44
Maternal Factors
- Age - Nutrition - Disease - Maternal emotional state
45
The squeezing that fetus experience during birth serves several important functions.
- Head reduces in size --> pass safely past pelvic bone - Withstand oxygen deprivation and regulate breathing - Pushing out amniotic fluid
46
State
Level of arousal and engagement in the environment, ranging from deep sleep to intens activity
47
Rapid Eye Movement (REM) Sleep
active sleep state characterized by quick, jerky eye movements under closed lids and associated with dreaming adults
48
Non-rem sleep
a quiet or deep sleep state characterized by the absence of motor activity or eye movements and more regular, slow brain waves, breathing and heart rate.
49
Swaddling
Wrapping baby in cloths, soothing technique
50
Colic
Excessive, inconsolable crying by a young infant for no apparent reason
51
Apgar score
Method for evaluating the health of the newborn immediately following birth based on skin tone, pulse rate, facial response, arm and leg activity, and breathing
52
Developmental resilience
Successful development in spite of multiple and seemingly overwhelming developmental hazards
