bulge = bulge
herniation = bulge which protrudes
herniated nucleus pulposis = tear in anular rring such that the center of the disk protrudes out of the disk space
It's is not one of the above that counts, but what problem it may be causing. For example, is it pressing on a nerve or the spinal chord?
