Arteria lumbalis

Arteria Lumbalis is a term used in anatomy to refer to the lumbar arteries, which are a group of arteries that supply blood to the lumbar region of the spine and the abdominal wall. These arteries are usually four in number on each side of the body, and they arise from the back of the aorta, opposite the bodies of the upper four lumbar vertebrae.

Anatomy

The Arteria Lumbalis are typically four in number and are located on either side of the aorta. They arise from the posterior surface of the aorta, opposite the bodies of the lumbar vertebrae. Each artery passes laterally and slightly upward, crossing the bodies of the vertebrae and the intervertebral discs.

Function

The primary function of the Arteria Lumbalis is to supply blood to the lumbar region of the spine and the abdominal wall. They also supply blood to the spinal cord, the vertebral column, and the muscles of the back.

Clinical Significance

The Arteria Lumbalis can be involved in various medical conditions. For instance, they can be affected by atherosclerosis, a disease in which plaque builds up inside the arteries. This can lead to reduced blood flow to the lumbar region, causing pain and other symptoms. In addition, damage or injury to these arteries can result in significant blood loss due to their large size and close proximity to the aorta.
