Vertebral Column, Intervertebral Disks and Nerves of the Body

A bulging disk simply extends outside the space it should normally occupy. The bulge typically affects a large portion of the disk, so it may look a little like a hamburger that’s too big for its bun. Usually bulging is considered part of the normal aging process of the disk and is therefore common to see on MRIs.

A herniated disk, on the other hand, results when a the center of the intervertebral disk (the nucleus pulposus) protruding out through the tough outer layer of cartilage (called the annulus fibrosus).  Herniated disks are also called ruptured disks.
