This is a good video describing the anatomy of a nerve.

The reason I posted this is because I have seen a few posts about the Myelin sheath. I think it is easy to get the impression that the myelin sheath is the outer most layer that surrounds the length of the pudendal nerve itself.
I don't think this is the case. The way I understand it is that the myelin is affected when a nerve is compressed and may have to regenerate but it cannot be damaged during surgery. For example it cannot be scraped off during surgery as It is inside the nerve itself surrounding the axons.
The connective tissue surrounding a peripheral nerve is called the epineurium. The picture on the neurawrap website shows this. Correct me if I am wrong but this is the way I understand it.
