Question

3 multiple choice 4 points a nerve impulse travels fastest along _____ axons of ____ diameter. myelinated; small unmyelinated; small myelinated; large unmyelinated; large none of the choices; axon diameter does not affect impulse conduction.

Explanation:

Myelinated axons have a myelin sheath that acts as an insulator, allowing for saltatory conduction which is faster. Larger - diameter axons have less resistance to the flow of electrical current, facilitating faster nerve - impulse conduction.

Answer:

C. myelinated; large
