PRIMITIVE REFLEXES Flashcards
are inborn reflexes which are present at birth and occur in a predictable fashion.
a normally developing newborn should respond to certain stimuli with these reflexes, which eventually becomes inhibited as the child matures
Neonatal Reflexes
stimulated by a sudden movement or loud noise
a normally developing neonate will respond by throwing out the arms and legs then pulling them towards the body
Moro Reflex
emerges 8-9 weeks in utero
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
what happen to the toes during the babinski (plantar) reflex?
the toes of the foot should fan out
the foot itself should curl in
when does babinski reflex emerge?
18 weeks in utero
when does babinski reflex disappear
6 months after birth
the child is placed on their back and will
- make fist
- turn their head to the right
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
and will curl in when the head moves forward
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.
stepping reflex
