Veins of the vertebral column
After completing this study unit you will be able to:
- Describe the venous drainage pattern of an individual vertebra.
- Identify the main collecting veins of each vertebral region.
The vertebral column is drained by four venous plexuses: the anterior external, anterior internal, posterior internal and posterior external vertebral venous plexuses. These plexuses communicate with each other through the intervertebral foramina and drain the external and internal regions of each vertebra.
Intervertebral veins drain the vertebral venous plexuses and travel through the intervertebral foramina to empty into the vertebral veins (cervical), the posterior intercostal veins (thoracic), the lumbar veins and the sacral veins.

That was a lot of veins to remember! Time to consolidate all of that knowledge with a quiz.

|Collecting veins by region||
Cervical: Vertebral veins
Thoracic: Intercostal veins
Lumbar: Lumbar veins -> Ascending lumbar veins
Sacrum: Sacral veins
