Motor development, control and learning Flashcards
When the posterior neural tube does not close it results in
Spinal bifida
Develops into the brain, spinal cord, or the CNS
The neural tube
Fibers begin in dorsal root ganglia and exit the spinal cord.
messages along these fibers carry____information
Afferent, Sensory
Fibers begin in ventral horn and carry____messages to the appropriate target.
Efferent, Motor
Lobe controls cognitive, impulse control and contains motor cortex
Frontal
Lobe control visual
Occipital
Lobe controls language centers
Temporal
Lobe receives messages from all sensory neurons
Parietal
Influences sexual behaviors, feeding, hormone output of the pituitary gland and body temp. regulation
Hypothalamus
The NS that can regenerate and what it is know as?
PNS regenerates after injury known as plasticity
Infant & toddler
0-3
Childhood
3-12
Adolesence
12-20
Young adulthood
20-40
Middle adulthood
40-65
Late adulthood
> 65
Motor development in neonatal and infants in 3 directions
Cephalocaudal, proximal-distal, flexion into extension
Landau reflex
airplane going from flexion to extension
what happens in a clonus fails to integrate and what motor skill is impacted>
there walking is affected and motor skill ambulation affected
Allows child to attain adequate nutrition? and when does it integrate?
the suck and swallow reflex
3-5months
Head control
4m
rolling
6-8m
Sitting
5-7m
Ambulation
12-15m
Cruising
10-11m
Crawling
9-10m
Aids in development of crawling and postural control. it is also felt to facilitate pelvic/hip movement.
Galant
Involuntary response to flex toward stimulates side
integrated?
if not integrated?
Galant reflex, 12m , muscular deformities
Curling of toes c pressure on ball and foot
Palmar grasps c pressure on the palm
Grasp reflex intergrated @ 9m
Fencing reflex seen at 3-5 months?
what learning takes place c this relfex?
Asymmetric tonic neck reflex, reaching out
Ipsilateral extremities extension contralateral extremities flexion on opposite side
establishes trust c caregivers and learns to be autonomous and uses sensory info to cue movement…developmental time?
Infancy
classifies objects according to certain characteristics this progression of thinking abilities is called concrete operations…development period
Childhood
practicing logic decision is present and has moved into the formal operations stage in which abstract problems can be solved…developmental time?
Adolescence
ability to separate movement in one body part from movement in another body part
dissociation
does a baby roll from supine<>prone or prone <>supine first
prone <>supine b/c extensor control precedes flexor control
