Question

The conduction of impulses through a myelinated fiber is called saltatory conduction.

• A. True
• B. False

Answer 1

The correct option is A

True

When a nerve impulse is conducted along a myelinated fiber, it “jumps” from node to node. This type of conduction is called saltatory conduction. An unmyelinated axon conducts an impulse over its entire surface, whereas, myelin prevents almost all flow of ions through the membrane that it encloses.
