Rapid impulse conduction from one node to the next on myelinated fibers is called _____ conduction.
A) synaptic
B) nodal
C) saltatory
D) transmission
E) neurilemmal

Question

Quizplus · Accepted Answer

Saltatory conduction is the rapid impulse conduction from one node of Ranvier to the next on myelinated fibers. This is because the myelin sheath prevents ion flow across the membrane, so the action potentials "jump" from node to node, allowing for faster transmission. Synaptic transmission, while involved in cell-to-cell communication, does not refer specifically to rapid conduction on myelinated fibers. Nodal and neurilemmal are not terms typically used to describe conduction, and transmission is too general.
