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

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 is a factor in the velocity of nerve impulse conduction?

The speed of action potential conduction along an axon Blank______ on the myelination of the axon.Multiple choice question.dependsdoes not depend

Which of the following statements about transmission of nerveimpulse is incorrect?(a) Nerve impulse travels from dendritic end towards axonal end(b) At the dendritic end electrical impulses bring about the releaseof some chemicals which generate an electrical impulse at theaxonal end of another neuron(c) The chemicals released from the axonal end of one neuron crossthe synapse and generate a similar electrical impulse in adendrite of another neuron(d) A neuron transmits electrical impulses not only to anotherneuron but also to muscle and gland cells

In __________Blank axons, impulse conduction is uninterrupted along the entire axon; while in __________Blank axons, action potentials only occur at nodes of Ranvier.Multiple Choicemyelinated; unmyelinatedunmyelinated; myelinated
