The axon has several roles in the neuron except:

A. action potential.

B. carring a neural impulse.

C. encased by myelin sheath.

D. receiving messages from other cells.

E. epolarization.

Receiving messages from other cells (D)

Explanation:

The Axon is a long slender projection of the nerve cell that transmits electrical impulses from the the cell body to the dendrites and other tissues in the body of a vertebrate like the bones, muscles and glands

while the dendrite is charged with receiving messages from other cells in the body of a vertebrate. the axon carrying a neural impulse and also depolarization (a change within a cell caused by change in electric charge distribution) and this change cause a decrease in the negative charge inside the cell. are some of the functions of the Axon as well.

The Axon is usually encased by myellin sheath

D. Receiving messages from other cells

Explanation:

The axon does not receive messages from other cells but rather transmits messages from cell body to the dendrites of other neurons or to other body tissue such as muscle, bone and so on. The dendrites are the one that receive messages from other cells. The axon is a long single fibre found in vertebrate animals. It is the part of the neuron that sends signals to synapses. Along with being long, they are slender, thin and tendril-like.
