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

Question

Quizplus · Accepted Answer

Saltatory conduction is the rapid conduction of nerve impulses along myelinated axons, which occurs because the myelin sheath insulates and speeds up the transmission of impulses by forcing them to "jump" from one node of Ranvier to the next. Large nerve fibers may contribute to faster conduction, but they alone do not enable saltatory conduction. There is no evidence to suggest that erratic transmission or diphasic impulses are involved in saltatory conduction.
