Myelin is important for action potential propagation. Multiple sclerosis is an autoimmune disease where the myelin sheath surrounding CNS axons is progressively lost. How will this degradation affect the generation of action potentials?

Solution Summary

This solution helps with a problem regarding action potentials.

Solution Preview

Firstly, consider what myelin does to propagate action potentials in axons.

Action potentials in neurons rely on ion channels along the membrane of the neuron (both soma and axon) which allow certain ions to flow in or out. The change in electrical voltage allows more channels downstream to open, eventually until neurotransmitter release at the end of the neuron is induced via ...

    This speeds up action potential travel down an axon about 20 fold as compared to axons lacking myelin. Events at a chemical synapse The action potential arrives at an axon terminal where there are Ca+ voltage-gated channels.

  • Discussion on various A&P questions

    When the myelin sheath is not present the action potential will move along an axon like a wave. But when the axon is myelinated, the action potential "hops" along the axon from gap to gap (nodes of Ranvier) between the myelin.

    Propagation of an Action Potential. An action potential travels away from its point of origin. An action potential is self-propagating. Threshold and the all-or-none phenomenon - Coding of stimulus intensity. a.

  • Myelin and the Myelination Process in CNS and PNS

    Gaps between myelin sheaths are called nodes of Ranvier. It is at these nodes that the action potential jumps along the axon making transmission velocities very high. CNS: Oligodendrocytes participate in myelination in the CNS.
