Myelin sheath increase speed
WebMyelin can greatly increase the speed of electrical impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length. What is the effect of myelin on conduction velocity? Myelination improves the conduction velocity—the speed with which action potentials travel—in axons. Web2 sep. 2024 · The fatty sheath increases the speed of the nerve impulses along the neuron. Myelination is the process of myelin developing around the axon fibres. It continues from birth to adolescence.
