Detailed explanation-1: -Myelin 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. Myelin damage causes several neurological diseases, such as multiple sclerosis.
Detailed explanation-2: -A myelin sheath is a sleeve (sheath) that’s wrapped around each nerve cell (neurons). It’s a protective layer of fat (lipids) and protein that coats the main “body” section of a neuron called the axon.
Detailed explanation-3: -High-fat diet in combination with exercise training increases myelin protein expression. PLP and MBP levels were highest in the group that exercised and consumed a high-fat diet. Exercise training or high fat consumption alone also increased PLP.
