Ranvier's Nodes MeSH Descriptor Data 2025

MeSH Heading: Ranvier's Nodes
Tree Number(s): A08.637.800.500.700; A08.675.542.512.560.700; A08.800.800.690.500.700; A10.755.503.700; A11.284.149.165.760; A11.650.800.500.700; A11.671.501.512.560.700
Unique ID: D011901
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D011901
Annotation: regular gaps in myelin sheath; A 11 qualif except /‌cytol; /‌genet permitted
Scope Note: Regularly spaced gaps in the myelin sheaths of peripheral axons. Ranvier's nodes allow saltatory conduction, that is, jumping of impulses from node to node, which is faster and more energetically favorable than continuous conduction.
Entry Term(s): Nodes of Ranvier
