Lumbar Vertebrae (5, L1-L5)

The Sacrum and Coccyx Coccyx Sacrum 5 fused vertebrae Blood vessels Nerves

Intervertebral Disk What type of cartilage is this?

Herniated Disks Swollen intervertebral disk pinches nerve Common in older individuals Some of us spring chickens suffer from this condition as well!

Herniated Disks are a major bummer, dude.

Spinal Abnormalities - Scoliosis Caused by disease or poor posture
