Newborns Flashcards
unlearned responses triggered by specific stimuli
newborn’s reflexes
many reflexes have survival value
-rooting, sucking, eye blinks
what does reflexes reflect on
the health of the child’s nervous system
what is the test to assess the newborn
APGAR
APGAR stands for
- appearance
- pulse
- grimace
- activity
- respiration
comprehensive evaluation of the well-being of a newborn
neonatal behavioral assessment scale (NBAS)
who made NBAS
berry brazelton
what does NBAS conclude
28 behavioral and 18 reflex items
what does NBAS assesses
- autonomic
- motor
- state
- social
the newborn’s states
- alert inactivity
- waking activity
- crying
- sleeping
calm, eyes open and attentive
alert inactivity
open but unfocused eyes
waking activity
motion is agitated and uncoordinated
crying
degree of activity and breathing alternate
sleeping
Starts softly and builds in volume and intensity
basic cry
more intense version of basic cry
mad cry
Starts with a loud wail, followed by a long pause, then gasping
pain cry
newborns sleeps
16-18 hrs a day
when a healthy baby dies suddenly for no apparent reason
sudden infant death syndrome
what is SID related to
sleep apnea and result of weak arousal reflex
risk factors of SIDS
- Premature
- low birth weight
- parents who smoke
- excessive blankets/overheating
specializes in sending and receiving information using electricity and chemicals
neurons
flat group of cells present in prenatal development that becomes the brain and spinal cord
neural plate
cells align them-selves with others cells and form structures.
aggregation
The number of synapses peaks at
12 months post conception
Gradual reduction in the number of synapses, beginning in infancy and continuing until early adolescence.
synaptic pruning
the study of brain waves recorded from electrodes that are placed on the scalp
electroencephalography (EEG)
The ____ detect, amplify, and record electrical activity in the brain.
electrodes
method of studying brain activity by using magnetic fields to track blood flow in the brain
functional magnetic resonance imaging (fMRI)
- Fewer synapses and dendritic spines in primary visual cortex
- Deficits in depth and pattern vision
visual deprivation
- Thicker cortexes
- Greater dendritic development
- More synapses per neuron
enriched environment
Baby’s toes spread out into a fan when bottom of foot is stroked in a forwards motion
babinski
Eye’s close in response to bright light or loud noise
blink
Baby extends arms outwards then inward forming a “C” with the hands when “falling”
moro
Baby will grasp objects placed in the hand
palmar
Lightly touching the infant’s cheek will cause it to turn towards the stimulus
rooting
When held upright and moved forward the baby will begin to move legs
stepping
baby will suck on objects that touch its lips
sucking
consistent style/pattern of behavior
temperament
Temperament reflects both
heredity and environmental experience
Infant temperament reflects mostly _______, while older children are more so influenced _____.
- hereditary factors
- by the environment
Once cells have been created through cell division in the neural tube , they will ______ to ______ either using ____ or _____
- migrate
- different places
- foot
- glial cells
