Human Development Flashcards
Fetal Sensorimotor Development
First trimester- sensory systems begin to develop
Second trimester- sensory systems become further refined
Third trimester- sensory systems are matured and functional, motor reflex are integrated by this time (palmar, plantar, rooting, MORO etc..)
Reflex that integrate during typical development
- rooting
- suck/swallow
- traction
- palmar grasp
- plantar grasp
- moro
- stnr
- atnr
- landau
-symmetric
-asymmetrical - tonic lab (prone/supine)
- galant
- neck righting/body righting
rooting reflex
stimulus- stroke mouth
response- movement of tongue, mouth or head during stimulus
purpose- help baby locate feeding source
28 weeks- 3 months
reflex starting at 28 weeks gestation
- rooting
- suck-swallow
- traction
- moro
- plantar grasp
suck swallow reflex
stimulus- finger inside mouth w/ head in midline
response- strong, rhythm sucking
purpose- facilitates sucking for swallowing liquid
28 weeks- 2 to 5 months
traction reflex
stimulus- grasp forearms and pull to sit
response- flexion of UE
purpose- create grasp to help child hold onto mother when being pulled
28 weeks- 2 to 5 months
moro reflex
stimulus- rapidly drop head backward
response- arm extension/abduction then arm flexion and adduction
purpose- develop proctective response, develop extensor tone when flexor tone is dominant
28 weeks- 4-6 months
plantar grasp
stimulus- apply pressure to ball of foot
response- toe flexion
purpose- increase input to sole of foot
28 weeks gestation- 9 months
galant reflex
stimulus- hold in prone and tap along spine w/ finger
response- lateral trunk flexion on stimulated side
purpose- stabilizing trunk
32 weeks- 2 months
asymmetric tonic reflex
stimulus- rotate head and hold for 5 sec
response- extension on face side, flexion on skull side
purpose- visual attention to UE, decreases rolling
37 weeks- 4-6 weeks
palmar grasp
stimulus- put finger in palm
response- finger flexion
purpose- increase palmar tactile input
37 weeks- 4 to 6 months
tonic-labyrinthine (supine)
stimulus- place in supine
response- increase extensor tone
purpose- full body extensor tone, allows posture to adapt to head
37 weeks- 4 to 6 months
tonic-labyrinthine (prone)
stimulus- place in prone
response- increase flexor tone
purpose- full body flexor tone, allows posture to adapt to head
37 weeks- 4 to 6 months
landau reflex
stimulus- hold in horizontal prone suspension
response- complete extension of head, trunk and extremities
purpose- regulates tone, promotes extension for flexor tone
3-4 months- 12 to 24 months
symmetric tonic neck reflex
stimulus-place in crawling position and extend head
response- flexion of hips and knees
purpose- promotes quadruped position for crawling, breaks up full body extension
4-6 months- 8-12 months
neck righting (on body)
stimulus- place in supine and fully turn head to one side
response- log rolling on whole body to maintain alignment
purpose- promotes rolling
4-6 months- 5 years
body righting (on body)
stimulus- place in supine, flex one hip and knee towards chest and hold
response- segmental rolling of the UE to maintain alignment
purpose- promote trunk and spinal rotation to facilitate sitting and quadruped positions
4-6 months - 5 years
reflexes that persist throughout life
- optical head righting
- parachute reflexes
- tilting reflexes
optical head righting
response- upright positioning of head
purpose- head management and postural stability
birth- 2 months
protective extension/parachute reflex
- reflex is used to break falls
downward parachute
- extension of LE
- 4 months
forward parachute
- extension of UE
- 6-9 months
sideward parachute
- arm extension and abduction to the side
- 7 months
backward parachute
- backward arm extension
- 9-10 months
tilting reflex
facilitates postural adjustment to maintain COG
prone tilting
- 5 months
supine/sitting tilting
- 7-8 months
quadruped
- 9-12 months
standing
- 12-21 months
Principles of motor development
- proximal to distal
- stability to controlled mobility
- ## gross motor to fine motor
