Yes, the human spine is composed of 26 bones called vertebrae.
The Vertebral Column
The vertebral column, also known as the spine, provides crucial support for the body and protects the spinal cord. Here's a breakdown of the vertebrae:
- Cervical Vertebrae: The first 7 bones in the neck region.
- Thoracic Vertebrae: The next 12 vertebrae in the chest area, each connected to a rib.
- Lumbar Vertebrae: The 5 vertebrae located in the lower back.
- Sacrum: One single fused bone below the lumbar vertebrae.
- Coccyx: Another single fused bone, located at the very end of the spine.
| Vertebrae Type | Number |
|---|---|
| Cervical | 7 |
| Thoracic | 12 |
| Lumbar | 5 |
| Sacral | 1 (fused) |
| Coccyx | 1 (fused) |
The vertebrae are not all independent bones. The sacrum and coccyx are each formed from the fusion of multiple bones. The 26 bones which make up the spine are the vertebrae.
