Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and spinal cord). In the PNS, one Schwann cell forms a ...
It causes demyelination, where the immune system attacks the myelin sheath, a protective layer of fat around brain and spinal cord nerve cells. This prevents the nerves from sending impulses or ...
Just like electric wires, your nerve cells have to be insulated in order to properly transfer messages. A fatty white substance known as myelin provides ... on the spinal cord and/or brain ...
The CNS consists of the brain and spinal cord ... ions into the cell, raising the voltage and depolarizing the membrane. As the voltage increases along the axon, additional sodium channels open, ...
You disconnect your cell phone from its charger as you get ready for a busy day. But even though it has been connected all night, the battery is only partially charged. You look at ...

Types of Neurons and Their FunctionNeurons are cells in the body that are responsible ... Motor neurons carry impulses away from the central nervous system (made up of the brain and spinal cord) and control the movement of the ...
Prior to that, he researched the role oligodendrocytes—the cells in the brain and spinal cord that produce myelin—play after spinal cord injury. He has several publications in peer-reviewed ...
OPCs are naturally occurring precursors to the cells that provide electrical insulation for nerve axons in the form of a myelin sheath. SCI most often occurs when the spinal cord is subjected to a ...
