This forms a kind of insulating layer around the nerve fibers and thus guarantees rapid transmission Sensory perceptions and stimuli.

The body suffers from one vitamin B12 deficiency, This myelin layer can no longer be sufficiently preserved and is gradually destroyed. As a result, the transmission function of the nerves is impaired and slowed down. But the protective layer around the nerve fibers is also missing, which causes further damage.
