Myelin sheath, a sleeve that protects a part of your nerve cells, and how it's related to multiple sclerosis. Read to learn more about its functions and how to protect it from damage.

The myelin sheath is a protective covering that surrounds fibers called axons, which are the long thin projections that extend from the main body of a nerve cell or neuron. This sheath is composed ...

The length of the myelin sheath along the axon is approximately 1 mm in the PNS. Between two adjacent myelin segments, there are approximately 1-μm-long gaps called nodes of Ranvier (Figure 1A ...

Sometimes it is shown as irregular bands radiating through the myelin sheath to the neurilemma, sometimes as a network particularly at the surface of the fibre or around the axon.

Brain injuries can also cause damage to myelin. Finding a way to help the sheath to repair itself could open the door to game-changing treatments for these conditions.

The myelin sheath that surrounds and protects nerve cells is made by cells called oligodendrocytes. In a person with MS, these cells are lost, so damaged myelin sheaths cannot be repaired.

In this image, an axon appears in green, while abnormal protein clumps (amyloid, red) lodge in tiny channels within the myelin sheath. Amyloid aggregates form filament-like strands across the ...

“If we learn how the proteins that make up the myelin sheath are affected in the diseased state compared to a non-diseased state, we might be able to figure out what’s going on when the disease ...
