Saltatory conduction

Definition

Saltatory conduction is the process by which nerve impulses jump between the nodes of Ranvier along myelinated axons, significantly speeding up electrical transmission. This method allows for faster communication between neurons without increasing the size of the axon.

Related terms

Nodes of Ranvier:

Gaps in the myelin sheath of a neuron's axon where saltatory conduction occurs.

Myelin Sheath:

A fatty layer that covers the axon of some neurons, providing insulation and increasing communication speed within the nervous system.

Action Potential:

A rapid rise and subsequent fall in voltage or electrical charge across a cellular membrane, primarily found in neurons, signaling down the axon
