    Definition of Myelination and conduction speed

    Check what you remember

    Read the wording for your board, then hide it and explain Myelination and conduction speed in your own words. Rough notes are fine. This is a self-check, with no mark or grade.

    Reference: Pearson Edexcel

    The myelin sheath insulates the membrane so depolarisation occurs only at nodes of Ranvier, and the impulse jumps from node to node in saltatory conduction, which is faster than continuous conduction in unmyelinated axons.
