Explain why the velocity of nerve impulse conduction in species B is more than species A?

To understand why the velocity of nerve impulse conduction in species B is greater than that in species A, we need to delve into the principles of nerve physiology, particularly focusing on how nerve impulses propagate along axons.

Nerve impulses, also known as action potentials, are electrochemical signals that travel along the length of neurons. The velocity of nerve impulse conduction is influenced by several factors, including axon diameter and myelination.

1. Axon Diameter: The diameter of the axon plays a crucial role in determining the velocity of nerve impulse conduction. Larger diameter axons offer less resistance to the flow of ions during action potential propagation compared to smaller ______ ______ _________ __________ _________.
