Myelination of the nervous system: mechanisms and functions

WebQ: What does the myelin sheath protect? A: Myelin sheath protects the nerves and enhances nerve transmission. Q: How does myelin affect learning? A: Myelination is a significant factor in how fast the neurons in our brain communicate. Information passes through axons covered in myelin much faster. WebThe best thing to do would be to surround this entire axon with a good insulator. And for the most part, that is true. It is surrounded by a good insulator. That is what the myelin sheath is. So let's say we want to surround this whole thing with just one big grouping of Schwann's cells, so one big myelin sheath-- which is a good insulator. drill for jewelry stones

At the Nodes of Ranvier the sheath thins. The action potential jumps from node to node, moving much more quickly than it would if it were propagated along the axon as a wave of depolarization. WebAdditionally, larger diameter axons tend to have thicker myelin. Figure 1.7. The diameter of the axon and the amount of myelination varies. Large diameter axons typically have thicker myelin sheath, which results in fast action potential speed. Small diameter axons may have no myelin present, resulting in slow action potential speed. e ottenfeld artist 1929 painting
