Which of the following is a benefit of saltatory conduction of myelinated nerves?
A) Speed of conduction is significantly lower.
B) More space is needed for myelinated nerves to conduct impulses.
C) Conduction amplitudes are much greater and last longer.
D) Amount of energy needed to propagate a nerve impulse is considerably less.

Question

Quizplus · Accepted Answer

Saltatory conduction of myelinated nerves allows for propagation of nerve impulses to occur more efficiently and with less energy. The myelin sheath insulates the axon, forcing the nerve impulse to jump from one node of Ranvier to the next rather than propagating continuously along the axon. This results in a faster speed of conduction and the ability for nerves to transmit signals over longer distances without loss of signal strength.
