equilibrium
protective
righting
primtive
________ and ________ reactions are complex postural responses that continue to be present even in adulthood.
equilibrium
protective
righting
primtive
Extremity movements in response to quick displacements of the center of gravity out of the base of support are called ________.
equilibrium
protective
righting
primtive
The righting reactions which persists are
neck (immature)
labyrinthine
optical
neck (mature)
Only few protective reactions persist
True
False
Only few equilibrium reactions persist
True
False
asymmetry during this reaction may indicate a brain lesion or injury or peripheral nerve problems to the upper extremity
Sucking
Rooting
Moro
Crossed Extensor
___________ is a primitive reflex which enables the child to hold onto the mother when being pulled
Sucking
Rooting
Moro
Crossed Extensor
Traction
this reflex is referred to as the "readiness tester". Integrates at the same time that independent gait first becomes possible.

often seen with children with athetoid CP

Plantar grasp
Flexor withdrawal
Crossed Extensor
Traction
____________ - prerequisite for spontaneous stepping reflex
Palmar grasp
Plantar grasp
Positive Supporting
Crossed Extensor
Traction
premature infants will tend to walk in a roe-heel fashion while more mature infants will walk in a heel-toe pattern.
Palmar grasp
Plantar grasp
Positive Supporting
Spontaneous Stepping
Traction
-_______ necessary to achieve quadruped crawling
STNR
ATNR
Positive Supporting
Spontaneous Stepping
Traction
persistence will impede activities which required graded coactivation of flexor and extensor muscles
STNR
TLR
Positive Supporting
Spontaneous Stepping
Traction
In testing for TLR, lift infant from prone to evaluate for presence of (a) tone.
In testing for TLR, lift infant from supine to sitting to observe for presence of (a) tone.
in order to move around in space, this reflex is necessary to allow the body to turn freely around the head
ATNR
TLR
LHR
STNR
necessary for the preservation of the center of gravity in prone
(a)
