Vertebrae are the skeletal portion of the spine Disk is the tissue that acts as a shock absorber to the spine and allows for movement. The disk lies in between each vertebrae.
it basically means that there is a small herniation (or bulging out) of one of the disks in your spine. L4-L5 is the position of the disk in your spine, and refers to Lumbar spine disk 4 and 5, aka it is to do with your lower spine. it can cause pain, or numbness and tingling in you lower legs in SOME cases..
When a fragment of the disk breaks away from the rest of the disk it can stay where it is or it may move out of place. Caudal loosely means tail, so "Caudal" migration means downward movement toward the bottom of the spine. If the disk fragment moves upward it would be "cephalad" or towards the head.
