Question

One neuron transmits a nerve impulse at 40 meters per second; another conduct at the rate of 1 meter per second. Which neuron has a myelinated axon?

Answer 1

Answer:

According to this information: One neuron transmits a nerve impulse at 40 meters per second; another conduct at the rate of 1 meter per second.

The neuron that has a myelinated axon is:

The first one/ the one that can emit a nerve impulse at 40 meters per second.

Explanation:

A myelinated axon is an axon that is covered by a myelin sheath that is made of Schwann cells. Thanks to this cover the axon is insulated, providing it the ability to increase the transmission of the action potential. Therefore, we can deduct that the axon that can emit a nerve impulse at 40 meters per second is myelinated.

Answer 2

Both are myelinated, however, the oligodendrocyte myelinates up to 40 axons and the schwann cells myelinates a section of one axon.
