Question

The myelination of central and peripheral axons occurs rapidly through the first few years of life. how can this development process explain the improved motor abilities of infants and toddler

Answer 1

without myelination, information about limb movement moves slowly to the CNS and motor commands move slowly back to the muscles. by the time the motor command has reached the muscle, it may no longer be appropriate. as the neurons become myelinated, the speed of action potential increases which is why we observe improved balance, coordination, and movement.
