Which of the following nerve fibers will have the highest conduction velocity when compared to an unmyelinated nerve fiber with conduction velocity = 0.35 m/sec.
A) a dendrite
B) a smaller unmyelinated nerve fiber
C) a myelinated nerve fiber the same size
D) a larger myelinated fiber
E) it is impossible to determine with the information provided.

Question

Quizplus · Accepted Answer

Larger myelinated fibers have the highest conduction velocity due to the combination of a larger diameter and myelination. This allows for faster propagation of action potentials compared to smaller unmyelinated fibers or myelinated fibers of the same size.
