Vena Spinalis (Noun)
Meaning
Veins that drain the spinal cord.
Classification
Nouns denoting body parts.
Examples
- The vena spinalis is a small extradural vein that collects blood from the spinal cord and is located in the posterior part of the vertebral canal.
- A network of tiny vena spinalis veins and sulcal veins helps to drain deoxygenated blood away from the spinal cord.
- An intradural vena spinalis or an anterior spinal vein is located in the anterior part of the vertebral canal and can drain into nearby veins and the internal vertebral venous plexus.
- Vena spinalis provide an important route through which deoxygenated blood is cleared from the spinal cord and directed towards veins that have connections to the body's systemic venous system.
- Because the arrangement of these vena spinalis is not well-standardized each one has the ability to connect and interlink at variable locations in the vertebral canal.
