Saltatory conduction in myelinated nerves Last Updated on Tue, 23 Mar 2021 | Membrane Potential In 1925 Lillie suggested that the function of the myelin sheath in vertebrate nerve fibres might be to restrict the inward and outward passage of local circuit current to the nodes of Ranvier, so causing the nerve impulse to be propagated from node Not only does saltatory conduction increase the speed of impulse transmission by causing the depolarization process to jump from one node to the next, it also conserves energy for the axon as depolarization only occurs at the nodes and not along the whole length of the nerve fibre, as in unmyelinated fibres. saltatory conduction: [ kon-duk´shun ] conveyance of energy, as of heat, sound, or electricity. aberrant ventricular conduction the temporary abnormal intraventricular conduction of supraventricular impulses; called also ventricular aberration . aerial conduction ( air conduction ) conduction of sound waves to the organ of hearing in the inner Rapid and efficient saltatory action potential conduction depends on the myelin sheath and clustered Na + channels at nodes of Ranvier. A new study convincingly shows that the periaxonal space is a necessary conductive component to accurately model myelinated axon physiology and saltatory conduction. Saltatory conduction in myelinated nerves Last Updated on Tue, 23 Mar 2021 | Membrane Potential In 1925 Lillie suggested that the function of the myelin sheath in vertebrate nerve fibres might be to restrict the inward and outward passage of local circuit current to the nodes of Ranvier, so causing the nerve impulse to be propagated from node Saltatory conduction (from the Latin saltare, to hop or leap) is the propagation of action potentials along myelinated axons from one node of Ranvier to the next node, increasing the conduction velocity of action potentials.
Seems to demarcate The pathophysiology associated with MS is the slowing or stopping of saltatory conduction of action potentials along myelinated axons in the CNS. This results Ranvier's nodes allow saltatory conduction, that is, jumping of impulses from node to node, which is faster and more energetically favorable than continuous Saltatory Conduction. Nodes of Ranvier tillåter aktionspotentialen att hoppa. Jonporter på andra sidan myelinet/Schwann Cellen öppnas så att potentialen förs Saltatory conduction.

Saltatory conduction depolarizes only a small fraction of the membrane (i.e., the cumulative exposed membrane surface in the nodes of Ranvier) when an action potential travels through the axon, as opposed to the whole membrane in an unmyelinated axon. Hence, less ions are transported across the membrane for any given action potential.

Even though strictly speaking, the signal doesn’t jump from one node to another, there is some moderately complex stuff going on in the background, during this type of conduction.
