Veins Spinal External Anterior

External anterior spinal veins (lat. v. spinales externae anteriores) are unpaired veins located on the sides of the anterior median sulcus of the spinal cord. They run along the entire length of the spinal cord, from the cranial openings of the spinal canal to the point of confluence into a single trunk - the anterior spinal vein.

The external anterior spinal veins collect blood from the anterior sections of the spinal cord, as well as from adjacent tissues and bones of the spine. They anastomose with the vessels of the dura mater and radicular veins. The diameter of the external anterior spinal veins increases in the caudal direction.

External anterior spinal veins (v.spinales externae anteriores) are a set of veins that drain blood from the spinal cord and cervical spine. They are part of the head and neck venous return system, which drains blood away from the brain and neck organs.

The external anterior spinal veins begin from the spinal roots C1-C8 and form two large trunks, which connect into one trunk passing through the cervical spine. They also contain small branches that drain into other veins.

The outflow of blood from the spinal external anterior veins occurs in the subclavian vein, the right and left internal jugular veins, and also in the superior vena cava. These veins play an important role in maintaining normal blood circulation in the brain and cervical spine, and also ensure the outflow of blood from the organs of the head and neck.
