Vertebrae With Nerves

12 vertebrae (T1–T12) attached to the rib cage.

The vertebral column, also known as the spine or backbone, is a complex structure composed of 33 vertebrae that extend from the skull to the tailbone. The vertebrae are divided into five regions: cervical (7 vertebrae), thoracic (12 vertebrae), lumbar (5 vertebrae), sacrum (5 fused vertebrae), and coccyx (4 fused vertebrae). Each vertebra has a unique shape and function, but they all share certain characteristics. vertebrae with nerves

| 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 | 12 vertebrae (T1–T12) attached to the rib cage

In conclusion, the vertebral column and nerves have a intricate relationship that is essential for maintaining proper bodily functions. Understanding the structure and function of vertebrae and nerves can help diagnose and treat various musculoskeletal and neurological disorders. Each vertebra has a unique shape and function,
