Question

Which is true about a neuron with a large diameter, myelinated axon as compared to a neuron with a small diameter, unmyelinated axon?

Answer 1

The true statement about a neuron with a large diameter, myelinated axon is that it conducts faster impulses than the  small diameter, unmyelinated axon.

A neuron is the nerve cell that conducts signals from the brain to the whole body and vice versa. The structure of the nerve cell comprises of a cell body with the hair-like dendrites emerging from it. One side of the nerve cell has a long axon that ends at the axon terminal.

Myelinated axon is the one that that is covered by myelin sheath all along its length. The sheath is composed of proteins and lipids. The myelinated axon conducts faster signal because the impulses jump upon the sheath rather than covering the whole length of the axon.
