Which of the following is a positive statement?
Action Potential Speed
The rate at which an action potential, or a short-lasting event of electrical charge reversal in a neuron, travels along a nerve fiber.
Saltatory Conduction
The process by which nerve impulses jump between the nodes of Ranvier in myelinated neurons, speeding up signal transmission.

Gaps in the myelin sheath of nerve fibers where the axonal membrane is exposed to the extracellular space, facilitating rapid signal transmission.
Action Potential
A rapid rise and subsequent fall in membrane potential across a cellular membrane, crucial for the propagation of electrical signals in nerve and muscle cells.
