The artery is generally eponymic, but it has several other names, including: great radicular artery of Adamkiewicz [7] major anterior segmental medullary artery; artery of the lumbar enlargement [8] great anterior radiculomedullary artery [9] great anterior segmental medullary artery [10] great ventral radicular artery [6]
In human anatomy, the anterior spinal artery is the artery that supplies the anterior portion of the spinal cord. It arises from branches of the vertebral arteries and courses along the anterior aspect of the spinal cord. It is reinforced by several contributory arteries, especially the artery of Adamkiewicz.
Anterior spinal artery syndrome is the most common form of spinal cord infarction. [1] The anterior spinal cord is at increased risk for infarction because it is supplied by the single anterior spinal artery and has little collateral circulation, unlike the posterior spinal cord which is supplied by two posterior spinal arteries.
This artery in turn receives its blood from the different radiculospinal branches, which are formed from the aorta and vertebral arteries. As the largest of the radiculospinal artery branches, the artery of Adamkiewicz provides a large amount of blood to the anterior spinal artery, thereby also supplying a good amount to the anterior spinal cord.
He is credited with describing the major anterior segmental medullary artery, which is also known as the Artery of Adamkiewicz. [2] In the early 1890s, Adamkiewicz published a series of articles claiming the discovery of a cancer-causing parasite he called Coccidium sarcolytus, as well as the existence of an anti-cancer serum.

The Tri-Cities of Virginia (also known as the Tri-City area or the Appomattox Basin) is an area in the Greater Richmond Region which includes the three independent cities of Petersburg, Colonial Heights, and Hopewell and portions of the adjoining counties of Chesterfield, Dinwiddie, and Prince George in south-central Virginia.
The geology of Virginia began to form at least 1.8 billion years ago. The oldest rocks in the state were metamorphosed during the Grenville orogeny , a mountain-building event beginning 1.2 billion years ago in the Proterozoic , which obscured older rocks.
