GENERAL HISTOLOGY

Detailed explanation-1: -Saltatory conduction describes the way an electrical impulse skips from node to node down the full length of an axon, speeding the arrival of the impulse at the nerve terminal in comparison with the slower continuous progression of depolarization spreading down an unmyelinated axon.

Detailed explanation-2: -However, nodes of Ranvier interrupt the insulation at intervals, and this discontinuity enables impulses to jump from node to node in a process known as saltatory conduction.

Detailed explanation-3: -The myelin sheath is wrapped around an axon in such a fashion, that there are a few gaps in between, these are called the Nodes of Ranvier. Simply put the impulse jumps from one node to the other node, hence called Saltatory Conduction.

Detailed explanation-4: -The Nodes of Ranvier are only present when the axon of a neuron is myelinated. Myelination allows for an increased rate of action potential transmission due to action potentials “jumping” between Node of Ranvier, this is called saltatory conduction.

Detailed explanation-5: -Answer and Explanation: An action potential (nerve impulse) is an electrical signal that travels down the axon of a neuron, resulting in the release of neurotransmitters into the synapse. An action potential occurs when the membrane potential of a specific cell rapidly changes.
