Veins Spinal External Posterior

External posterior spinal veins (v. spinales externae posteriores) are venous vessels that pass along the posterior surface of the spinal cord, flow from its roots and branches and flow into the vertebral venous sinus. These veins are part of the larger cerebral venous system and play an important role in the drainage of blood from the spinal cord and nerve roots.

The external posterior spinal veins are located on the posterior surface of the spinal cord along its roots. They start from the roots of the spinal cord in the spine and pass along its posterior surface, forming the venous plexus. They then connect with other veins, such as the vertebral veins, and empty into the sinus venosus, which is located in the spinal region.

The main function of the spinal external posterior veins is to drain blood from the spinal cord. They divert blood from the roots, where it is saturated with oxygen and nutrients, and transfer it to the venous system of the brain. In addition, the spinal posterior external veins are involved in draining cerebrospinal fluid from the brain and other fluids that form in the nervous system.

The external posterior veins of the spinal cord are important for the normal functioning of the nervous system. They ensure effective outflow of blood from the spinal cord and its roots, which helps maintain normal blood circulation and metabolism in the nervous tissue. Disturbances in the functioning of the spinal posterior external veins can lead to various diseases of the nervous system, such as inflammation of the spinal roots or disruption of the venous outflow from the brain.

Thus, the spinal external posterior veins play an important role in the functioning of the nervous system and maintain its normal functioning. Knowledge of the anatomy and physiology of these vessels can help in understanding the processes occurring in the nervous system and in the treatment of various diseases associated with impaired venous outflow.

The veins of the spinal vertebral canal are present in the spinal vertebral canals, connecting them with tributaries. Into the spinal canals, the vertebral venous tributaries open posteriorly, below within the ligamentum flavum. On the lateral wall of the spinal canal, the vertebral venous canal is divided into an outer diameter and a superior diameter, which are widely connected to each other to form the vertebral vein.
