On top of that, they also give structure and support to our neurons and they protect and cushion those neurons so that they aren't damaged in any way. Now, Schwann cells are very similar to oligodendrocytes in a sense that they create the myelin on the neurons found in the peripheral nervous system. So these Schwann cells basically attach physically attached to our sections on our axon and then they secrete that myelin material onto our axon. So these are the Schwann cells. So notice that they're different from oligodentrocytes which are separated from the axon. So this is the body of the ligamentrocyte while this is the body actually attached onto the axon of that neuron.
