Question

Which of the following does NOT influence the time necessary for a nerve impulse to be conveyed by a particular neuron?

A. length of the axon

B. presence or absence of a myelin sheath

C. diameter of the axon

D. presence or absence of nodes of Ranvier

E. whether axon is sensory or motor

Answer 1

The diameter of the axon does not influence the time necessary for a nerve impulse to be conveyed by a particular neuron.

Step-by-step explanation:

The diameter of the axon does not influence the time necessary for a nerve impulse to be conveyed by a particular neuron. The length of the axon, the presence or absence of a myelin sheath, the presence or absence of nodes of Ranvier, and whether the axon is sensory or motor all play a role in the speed of nerve impulse transmission.
