(also known as the &#039;&#039;&#039;Batson venous plexus&#039;&#039;&#039;) are a network of veins located within the [[vertebral column]]. These plexuses are divided into two main groups: the internal vertebral venous plexus and the external vertebral venous plexus. They play a crucial role in the venous drainage of the [[spinal cord]] and the [[vertebrae]].<br /> <br /> ==Anatomy==<br /> The vertebral venous plexuses are divided into:<br /> * &#039;&#039;&#039;Internal vertebral venous plexus&#039;&#039;&#039;: This plexus is located within the [[vertebral canal]] and is situated between the [[dura mater]] and the [[vertebrae]]. It is further divided into anterior and posterior internal vertebral venous plexuses.<br /> * &#039;&#039;&#039;External vertebral venous plexus&#039;&#039;&#039;: This plexus surrounds the vertebrae and is also divided into anterior and posterior components.<br /> <br /> ==Function==<br /> The vertebral venous plexuses are valveless veins that provide a pathway for venous blood to return from the [[spinal cord]] and the [[vertebrae]] to the [[systemic circulation]]. They are important for maintaining the [[cerebrospinal fluid]] pressure and play a role in the spread of [[metastasis|metastatic]] cancer cells and [[infection]]s due to their valveless nature.<br /> <br /> ==Clinical significance==<br /> The vertebral venous plexuses are clinically significant because they can serve as a route for the spread of [[cancer]] and [[infection]]s. Due to the lack of valves, increased intra-abdominal or intrathoracic pressure can cause a reversal of blood flow, potentially leading to the spread of disease.<br /> <br /> ==Related pages==<br /> * [[Spinal cord]]<br /> * [[Vertebrae]]<br /> * [[Dura mater]]<br /> * [[Cerebrospinal fluid]]<br /> * [[Metastasis]]<br /> * [[Infection]]<br /> <br /> [[Category:Veins]]<br /> [[Category:Anatomy]]<br /> [[Category:Spinal cord]]<br /> <br /> {{Anatomy-stub}}</div> Prab
