So you put those gaps in here, so these are the myelin sheath. And this right over here is a node of Ranvier. These are nodes of Ran-Veer, or Ranvier. And right in those little nodes, right in those nodes, right where the myelin sheath isn't, we can put these voltage-gated channels to essentially boost the signal.

Webb6 sep. 2024 · Oligodendrocytes generate myelin. Myelin, in turn, forms a protective sheath covering each nerve cell’s axon – the threadlike portion of a cell that transmits electrical signals between cells. Damage to myelin is associated with MS, stroke, brain injuries, and certain forms of dementia such as Alzheimer’s disease. WebbMultiple sclerosis (MS) literally means “many scars,” which refers to the lesions that accumulate in the brain and spinal cord throughout the course of the disease. These scars, or lesions, consist mostly of dead nerve cells, whose axons have been denuded of the myelin sheaths that normally protect them and permit the conduction of nerve impulses. … WebbSchwann cell, also called neurilemma cell, any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons. Schwann cells are named after German physiologist Theodor Schwann, who discovered them in the 19th century.
