PRIMITIVE REFLEXES Flashcards
are inborn reflexes which are present at birth and occur in a predictable fashion.

a normally developing neonate will respond by throwing out the arms and legs then pulling them towards the body
Moro Reflex

inhibited by 16 weeks
Moro Reflex
when does moro reflex emerges?
8-9 weeks
when is moro reflex inhibited?
16 weeks
stimulated when an object is placed into the baby’s palm
a normally developing neonatal responds by grasping the object
palmar grasp
a persistent palmar grasp reflex may cause issues such as
swallowing and delayed speech
when does palmar grasp emerges
11 weeks in utero
when does palmar grasp inhibits
2 to 3 months after birth
stimulated by stroking the sole of the foot
babinski (plantar) reflex

asymmetric tonic neck reflex
asymmetric tonic neck reflex is present at what weeks-old
18 weeks in utero
when does asymmetric tonic neck reflex disappear
6 months after birth
arms and legs extend when head moves backward

tonic labyrinthine reflex
when does tonic labyrinthine reflex emerge
emerges in utero until four months post-natally
The neonates back is stimulated
their trunk and hips should move toward the side of the stimulus.
This turning of the torso aides in neonatal and toddler movement, such as crawling and walking.
galant reflex
when does galant reflex emerges?
20 weeks in utero
when does galant reflex inhibits
9 months
if the galant reflex persists, what can it effect to the infant?
the walking posture
This turning of the torso aides in neonatal and toddler movement, such as crawling and walking.
galant reflex
Neonate will make walking motions with legs and feet when held in an upright position with the feet touching the ground.

it appears at birth and lasts for 3 to 4 months
when does stepping reflex reappear?
12-24 months
When neonate is placed on stomach, their back arches and head raises.
Landau’s Reflex
If landau’s reflex does not occur, it is an indication of a
a motor development issue
generalized intellectual impairment
cerebral palsy
when does landau’s reflex emerges
3 months post natally
until what age is landau’s reflex
until the child is 12 months old.
The baby’s cheek is stroked:
they respond by turning their head towards the stimulus
they start sucking, thus allowing for breastfeeding.
