Vein Vertebral External Anterior

The anterior external vertebral vein is a vessel that is located in the spinal canal between the upper edge of the 5th cervical and first thoracic vertebrae. It is one of the components of the vertebral vein system and is involved in the drainage of cerebrospinal fluid and other body fluids that circulate throughout the skull and neck.

The vertebral external anterior vein is a branch of the vertebral external vein, which in turn is part of the great external vein. The vein is about 6 - 7 centimeters long, and flows into the large external vein, which protrudes through the spine, passing through its body.

The external and internal anterior vertebral vein are one of the large venous collectors in the spinal canal.

The vertebral vein drains into the sigmoid vein where the anterior venous plexus is formed. It is joined by 5 smaller veins: the thyroid, jugular, sternocleidomastoid, scapular and terminal vein of the vertebral system.

The anterior branch of the external vertebral vein is a direct continuation of the spinal canal in front of the transverse processes of the sacral vertebrae. Its source lies between the sacrum and the sacrospinous ligament. Located in the costovertebral groove in front of the legs of the lower ribs, it connects with the posterior branch of the same name. Superiorly, it opens into the epidural space in front of the posterior sacral artery and the anterolateral branches of the sacral plexus. In the zone of connection of the anterior longitudinal fasciculus with the inner layer of the dura mater, it crosses its outer plate and is divided into anterior, medial and posterior roots. On the right and left it forms oblong sinuses, which connect with the limban II and III order in two, forming the ducts of Sinque. Rapid attachment of the anterior branch of the external vertebral veins to the muscle bundles of the tendon helmet, to the openings of the heel cords on the inside. and to the tendons of the deep sheaths of the peroneal muscles.
