Allow me to teach you a little about your back before explaining what this is... Looking down on the involved levels (L5-S1), the top is toward your abdomen (NOON) and the back is toward the back (6 O'clock). I'll describe what happens, referring to times on the clock. Between each vertebra are thick disks: these comprise of a thick wall on the outside, filled with a thick gel. This acts as a "shock absorber". Over the years these disks begin to wear out and flatten or possibly bulge out (like squashing a marshmallow). Sometimes, trauma --or bending or leaning with/without heavy lifting-- can cause a herniation in the side of this disk, and the resulting herniation can cause problems by pinching a nerve. If the herniation occurs at 5 o'clock or 7 o'clock, the herniation can pinch (trap) a nerve as it is preparing to leave the spinal cord and travel down the body, resulting in a severe burning pain and possibly muscle cramps if the nerve travels to the spasming muscle. The disc can also bulge out and NOT press on a nerve, but can still cause a great deal of low Back pain because of damage to the nerves in the disc. This, I believe is what this MRI refers to...
Your back hurts.
A volcano!
The function of the central disk on the starfish is to regrow an appendage if one is cut off. It is where the arms of the starfish originate.

Yes
herniated disk
I am learning about this in my Science class, and when a geologist looks at an extrusion, they know it's an extrusion because it is Igneous rock, and an extrusion helps tell the reletive ages of the layers around it.
DISK
The central region, more commonly known as the Central Disk, is the middle of the starfish where the rays start to grow. The Central Disk also contains the pyloric stomach, the anus, the Madreporite, and the stone canalwhich connects the Madreporite to the inner organs.
The Lepore Extrusion was created on 2006-10-17.
The Mary-Sue Extrusion was created in 1999.
