The human spine is a complex architectural marvel that serves as both a sturdy scaffolding for the body and a protective conduit for the central nervous system. The relationship between is fundamental to every movement, sensation, and autonomic function we experience. The Anatomy of Vertebrae and the Spinal Cord Spinal cord │ ├── Dorsal root ganglion (sensory)
| Condition | Mechanism | Effect | |-----------|-----------|--------| | | Disc compresses nerve root in intervertebral foramen | Radiculopathy (pain/numbness in dermatome) | | Spinal stenosis | Narrowing of vertebral canal or foramina | Neurogenic claudication | | Foraminal encroachment | Osteophytes (bone spurs) from vertebrae compress nerve | Cervical or lumbar radiculopathy | | Spondylolisthesis | Vertebra slips forward, stretching/tethering nerve roots | Lower limb weakness, bladder issues (cauda equina risk) | | Shingles (Herpes zoster) | Virus reactivates in dorsal root ganglion | Dermatomal rash and pain | The relationship between is fundamental to every movement,
The nerves that arise from the vertebrae are:
