nodes of ranvier (n)

small gaps in the myelin sheath of medullated axons

No Synonyms and anytonyms found

The nodes of Ranvier are specialized regions along the axon of a neuron where the myelin sheath is thinner.
The nodes serve as gaps between myelinated segments, allowing ions to flow in and out during the transmission of electrical signals.
The distribution of nodes along the axon determines the saltatory conduction of nerve impulses.
In certain neurological disorders, such as multiple sclerosis, the nodes of Ranvier are damaged, which disrupts nerve communication.
The voltage-gated sodium channels are highly concentrated at the nodes of Ranvier, enabling the rapid propagation of action potentials.
The length of the internodal segments between the nodes influences the speed of electrical conduction.
Myelinating cells, known as Schwann cells or oligodendrocytes, form the myelin sheath that insulates the axon and creates the nodes of Ranvier.
The gaps between the myelin sheaths at the nodes of Ranvier are essential for the proper functioning of the nervous system.
Researchers are investigating ways to repair or regenerate damaged nodes of Ranvier as a potential treatment for neurological diseases.
The nodes of Ranvier are named after the French physiologist Louis-Antoine Ranvier, who first described them in 1878.
