Question

Duct tape is to its cardboard roll as the myelin sheath is to the
A)dendrite.
B)axon.
C)soma.
D)interneuron.

Accepted Answer

The myelin sheath is a layer of insulation that wraps around the axon of a neuron, much like duct tape wraps around a cardboard roll. The axon is responsible for carrying electrical impulses away from the neuron's cell body (soma), so option B is the best choice.
