Question

What is saltatory conduction?

• A. The conduction of impulses through an unmyelinated fiber.
• B. The conduction of impulses through a myelinated fiber.
• C. The conduction of impulse all through out the body.
• D. None of the above

Answer 1

The correct option is B

The conduction of impulses through a myelinated fiber.

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.
