본문내용

* neural myelination
: begins between the 10th and 15th week of gestation
: is complete by about 5 years of age

* axon reach the adult diameter
: at 8-10 years of age

* the large ulnar motor axons
: 3.5-4 um in 1 months preterm infants
: 4-6 um in term infants
: 9-13 um in adults

* no correlation between birth weight and NCV

* ulnar nerve conduction velocity
: 20m/s for premature infants
: 28m/s for term newborns
(half of the average adult value 60m/s
: normal NCV values
- are achieved by 3-5 years of age

* median CMAP amplitude
: average 4mV at 1 months of age
: increase to 14.1mV at 6-11 years of age

* increased temperature
 increase NCV
: critical in infants
