reflex and stereotypes Flashcards
in what months does movements of infancy occur as reflexive
4 months before birth to 4 months after birth
what does subcortically mean and what about it
it means below the cortex of brain, and it is where reflexes occur
what are the primitive reflexes
are those that appear during gestation or at birth and are suppressed by six months age
what is postural reflex
reflexes related to the development of later voluntary movement
primitive reflexes include
palmar grasp
sucking
rooting or search reflex
moro
startle
asymmetric tonic neck
symmetric tonic neck
plantar grasp
Babinski]
babkin [palmar mandibular reflex]
galant
postural reflexes
stepping reflex
crawling
swimming
head and body righting reflex
parachuting [proping reflex]
labyrinthine
pull up
which reflex start at 5 months of gestation and endures to 4 to 6 months after birth
palmar grasp
which reflex start at 5 months of gestation and endures to 4 to 6 months after birth
palmar grasp
they are often stimulated by touching of lips, normally present prenatally and remain a reflex through 3 to 4 months and after will be voluntary
sucking reflex and rooting or search reflex
what is moro reflex and how long it lasts
sudden extends of limbs as a result of loud Noice or touch and release, usually presence at birth and last to 4-6 mnths
which reflex is most useful in diagnosing infant’s neurological maturation
asymmetry of this reflex may indicate injury of one side of brain
also, may indicate sensorimotor problem
moro reflex
what does startle reflex do
it acts the same as moro reflex but it allows flexion instead of extension and it may not appear until after 2 to 3 months after moro disappears and usually suppress by 1 year of age
asymmetry tonic neck reflex
commonly in premature babies
elicited when baby in prone or supine
when turning the head to one side the limbs on that side flex while the opposite limbs flex
up to 3months
help to developed eye hand coordination
symmetry tonic neck
in supported sitting
if baby tipped backward arms extends legs flex but if tipped forward opposite occurs
from birth to 3 months
plantar grasp
from birth through a year
slight pressure on foot ball
it will be suppressed before walking
Babinski
a faithful test for pyramidal tract
first year of life 9 to 12 months
from birth
result in dorsiflexion of great toes or all fingers
babkin
normally at birth
on palm
mouth open, eye closed neck flex head tilting forward
disappear at 3 months
galant reflex
in prone
firm sharp stimulation applied
onset 32 weeks of gestation
9 to 12 months
stepping reflex
few weeks
5 or 6 months
crawling
from birth
3 to 4 months
it is essential for furthering development of sufficient muscular tone for future voluntary creeping
swimming
2nd neonatal week
5 months
head and body righting reflex
head righting at 1st month by turning the body to certain direction than the head follows normally disappeared at 6 months.
body righting until 5th month last through 1 yr
parachuting or proping
protective movement in the direction of potential falling
downward 4 months
sideward 6 months
backward 10 months
labyrinthine
2 to 3mnths
1st year
tilting head to the opposite direction as the body
pull up
3rd month
1st year
stereotypes
they increase throughout the year
frequency of occurring increase throughout the first year
