Artery Spinal Dorsal

The dorsal spinal artery (a.spinalis dorsalis) is one of the branches of the posterior cerebral artery. It runs along the back of the spinal cord and supplies blood to the back of it.

The dorsal spinal artery begins from the posterior cerebral artery, which is a branch of the internal carotid artery. It crosses the spinal cord and runs along its posterior surface.

Along its path, the dorsal spinal artery branches into many small arteries that supply blood to the posterior parts of the spinal cord. This includes the lumbosacral region, the sacral region, and the coccygeal region.

Insufficient blood supply to the spinal cord can lead to various diseases, such as radiculitis, myelopathy and others. Therefore, it is important to monitor the condition of the arterial system and undergo regular medical examinations.

In addition, the dorsal spinal artery can be damaged due to spinal injuries or surgical interventions on the spinal cord. In such cases, surgery may be required to restore blood flow.

Thus, the dorsal spinal artery plays an important role in supplying blood to the spinal cord, and its normal functioning is of great importance for human health.

The spinal dorsal artery (SDAR) is a medium-sized artery that supplies the spinal cord as well as the nerve roots, dorsal fascia, and cartilage tissue of the spine. It is one of the most important arteries of the back and ensures the normal functioning of all structures associated with the back. In this article we will review the origin, anatomy, function and clinical significance of the dorsal spinal artery.

Origin: SDAR is formed as a result of the fusion of two posterior intercostal arteries. They arise from the anterior intercostal artery, which is located on the inside of the spine. One SDAR from each intercostal artery. Both SDARs extend at the same angle so that
