Answer:
e. whether or not the impulse begins in the CNS
Explanation:
Nerve impulse is action potential movement through the axon. Nerve impulse propagation has its velocity (speed at which nerve impulse travels down the axon) which depends on many factors. For example, myelination increases the conduction velocity. Also, the larger the diameter of an axon, the higher the velocity is. Nodes of Ranvier present on the axons, and myelin sheath between the nodes act as a good electrical insulator which also increases the velocity.
