The spine is made up of a column of small bones called vertebrae that surround and protect the spinal cord and nerves that branch out from the spinal cord. Each bone or vertebra is separated from the other by a spongy tissue called an intervertebral disc, which acts as a cushion and prevents the bones from rubbing against each other during movement.
Based on their position, the vertebral column is categorized into 7 cervical vertebrae in the neck, 12 thoracic vertebrae in the chest region, 5 lumbar vertebrae in the lower back, and 5 fused bones of the sacrum and 3 fused bones that form the coccyx in the pelvic region.
Some of the common spinal disorders include:
- Degenerative disc disease (DDD)
- Herniated disc
