Loss of myelin—the fatty substance that surrounds the axons of nerve cells—is one of the reasons nerve cells fail to recover after injury and in some diseases. WebThe myelin sheath is not actually part of the neuron. Myelin is produced by glial cells. Along the axon there are periodic gaps in the myelin sheath. These gaps are called nodes of Ranvier and are sites where the signal is “recharged” as it travels along the axon. WebThe myelin sheath is the product of the Schwann cells which are trapped inside, it's very easy for people to get confused between the two. An analogy would be a very hairy dog.
