Neurons with a myelin sheath conduct nerve impulses  afaster than neurons without myelin sheaths bslower than neurons without myelin sheaths cthe same speed as neurons without myelin sheaths din greater numbers than neurons without myelin sheaths

One neuron (A) transmits a nerve impulse at 40 meters per second and another neuron (B) conducts the impulse at 1 meter per second. Which neuron has myelinated axon?

Which of the following does not influence the time necessary for a nerve impulse to be transmitted? diameter of the axon length of the axon presence or absence of a myelin sheath presence or absence of nodes of Ranvier whether or not the impulse begins in the CNS

A physiologist testing signal transduction rates in two different nerve fibers notices that one fiber conducts signals much faster than the other. Which is the most likely difference between the two?Multiple ChoiceThe faster nerve fiber is myelinated and the slower one is not.The slower nerve fiber is myelinated and the faster one is not.The faster nerve fiber has more dendrites.The faster nerve fiber has more axons.

Neurons carrying nerve impulses toward the CNS are neurons while neurons carrying nerve impulses from the CNS to the periphery are neurons.
