In which type of axon will velocity of action potential conduction be the fastest?

Myelinated axons with the largest diameter

Explanation:

Axons are parts of a nerve cell in which impulses are conducted from the cell body to other cells while myelin is a fatty substance that surrounds the axon.

This is because the large diameter facilitates the flow of depolarizing current through the cytoplasm. The myelin sheath insulates the axons and prevents current from leaking across the plasma membrane.

Myelinated axons with the largest diameter

Explanation:

Axons are fibers of the nerves that are responsible for the transmission or movement of impulses or signals away from the cells of the body.

Myelinated axons are axons that have an external wrapping or cover know as the myelin sheath. The effect of the myelin sheath on axons is that it increases the rate at which electrical nerve signals are transmitted along the fibers of the nerves. The transmission of signals in myelinated axons is in saltare( hop) movement.
