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.
The spinal veins (veins of the medulla spinalis or veins of the spinal cord) are situated in the pia mater and form a minute, tortuous, venous plexus. They emerge chiefly from the median fissures of the medulla spinalis and are largest in the lumbar region. In this plexus there are:
Vascular myelopathy (vascular disease of the spinal cord) refers to an abnormality of the spinal cord in regard to its blood supply. [1] The blood supply is complicated and supplied by two major vessel groups: the posterior spinal arteries and the anterior spinal arteries—of which the Artery of Adamkiewicz is the largest. [2]
Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).
It is called anterior spinal artery syndrome. This occurs when the disruption of the anterior spinal artery is at the level of the spinal cord. Contrast this with medial medullary syndrome, when the anterior spinal artery is occluded at the level of the medulla oblongata. [citation needed]
The internal vertebral venous plexuses (intraspinal veins) lie within the vertebral canal in the epidural space, [1] [2] embedded within epidural fat. [2] [3] They receive tributaries from bones, red bone marrow, and spinal cord. They are arranged into four interconnected, vertically oriented vessels - two situated anteriorly, and two ...
During embryological development, about 75% of the segmental medullary arteries regress, forming the thinner (anterior and posterior) radicular arteries (which supply the two roots and sensory ganglion of each spinal nerve); the remaining segmental medullary arteries persist to contribute arterial supply to the spinal cord, as well as giving rise to the aforementioned radicular arteries.
