Which two factors affect the speed at which the action potential is conducted along a neuron's axon?
A) the diameter of the axon and whether the axon is wrapped in a myelin sheath
B) the number of dendrites and the size of the cell body
C) the type and number of axons projecting from the neuron
D) the size of the positive electrical charge just before an action potential occurs and the number of adjacent neurons

Quizplus · Accepted Answer

The diameter of the axon and whether the axon is wrapped in a myelin sheath affect the speed at which the action potential is conducted along a neuron's axon. A wider diameter and the presence of a myelin sheath increase the speed of conduction by reducing resistance and allowing for saltatory conduction. The other options mentioned do not directly affect the speed of conduction along an axon.
