Action potentials are conducted more rapidly along an axon with a Blank______ diameter.Multiple choice question.largersmaller

Break Down the Problem

1. Identify the nature of action potentials in axons.
2. Understand the impact of axon diameter on conduction velocity.

Relevant Concepts

1. The conduction velocity of an action potential is influenced by both the diameter of the axon and the presence of myelination.
2. Larger axons have less internal resistance and allow for faster conduction of action potentials.

Analysis and Detail

1. Axon Diameter: The larger the diameter of an axon, the lower the internal resistance to the flow of electrical current (ions). This allows the action potentials to propagate more quickly.
2. Myelination: In addition to diameter, myelinated axons conduct action potentials faster than unmyelinated axons, but here we are specifically focusing on the diameter.

Verify and Summarize

• A larger diameter reduces resistance and enhances conduction speed, while a smaller diameter would have the opposite effect.

Final Answer

Action potentials are conducted more rapidly along an axon with a larger diameter.
