Question

Which of the following effects does myelination have on the nervous system? It increases the speed and efficiency of information traveling through the nervous system. It increases the blood-flow to the brain, spinal cord, and surrounding areas. It improves the quality of sleep in children. It aids the functioning of connective tissues in the bodies of infants and young children.

Answer 1

The correct answer is "It increases the speed and efficiency of information traveling through the nervous system".

Step-by-step explanation:

Myelination is a complex process that results in the ensheathment of axons by adding myelin to particular regions of the axons, which increases the speed and efficiency of information traveling through the nervous system. Myelin acts like an electrical insulator, speeding up the action potential conduction of the neurons' electrochemical signals. Myelinated axons can conduct at velocities up to 150 m/s, while unmyelinated axon conduction velocities could be as low as 0.5 m/s .
