infants with CNS damage have ___ primitive reflexes and ____ postural reactions
stronger and more sustained primitive reflexes
delayed development of postural reflexes
primitive reflex
these develop during gestation and are present at birth. usually disappear between 3-6 months of age.
postural reactions
not present at birth- they are acquired.
4 primitive reflexes
moro, hand grasp, atonic neck reflex, rooting
moro reflex
abduction and extension of arms with trunk extension. then adduction of upper extremities. present at birth, gone by 4 months
hand grasp reflex
grasp anything placed in palm. present at birth, gone by 1-3 months
atonic neck reflex

rooting reflex
turn head toward same side as stimulus when corner of mouth is stimulated. present at birth and gone by 6 months.

head righting
ability to keep head vertical despite body being tilted. appears at 4-6 months and persists
parachute
outstretched arms and legs when body is moved head first in down direction. seen at 8-9 months and persists
fine motor milestone at birth
hands kept tightly fisted
