Saltatory conduction is made possible by________.
A) diphasic impulses
B) the myelin sheath
C) erratic transmission of nerve impulses
D) large nerve fibers

Question

Quizplus · Accepted Answer

Saltatory conduction is the rapid conduction of nerve impulses along axons that have a myelin sheath. The myelin sheath interrupts the continuity of the axon and forms small gaps called nodes of Ranvier. Saltatory conduction occurs when the impulse jumps from one node to the next, skipping the myelinated portion of the axon. This allows for faster conduction and conserves energy. Therefore, option B is the correct answer.
