Ranvier's Nodes (Noun)
Meaning
Small gaps in the myelin sheath of medullated axons.
Classification
Nouns denoting body parts.
Examples
- Ranvier's nodes are small gaps in the myelin sheath of medullated axons where the action potential can jump from node to node.
- The myelin sheath is interrupted at regular intervals by gaps called Ranvier's nodes, which allow the action potential to propagate.
- Ranvier's nodes are critical for the proper functioning of the nervous system, as they enable the rapid transmission of electrical signals.
- The nodes of Ranvier are the gaps in the myelin sheath where the axon is exposed and the action potential can jump from node to node.
- In the peripheral nervous system, Ranvier's nodes are the sites where the myelin sheath is interrupted, allowing the action potential to propagate.
