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 .
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 ...
The basilar artery is the main blood supply to the brainstem and connects to the Circle of Willis to potentially supply the rest of the brain if there is compromise to one of the carotids. At each cervical level, the vertebral artery sends branches to the surrounding musculature via the anterior spinal arteries.
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 ...
Beginning in 1937 Batson began a series of injection experiments investigating the anatomy and physiology of the cerebrospinal venous system. [2] His carefully documented results demonstrated the continuity of the venous systems of the brain and the spine, as injections of contrast dyes into venous systems feeding into the spinal venous plexus led to the appearance of contrast material in the ...
The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle, [3] allowing for the flow of CSF to circulate. [ 3 ] [ 4 ] All of the ventricular system and the central canal of the spinal cord are lined with ependyma , a specialised form of epithelium connected by tight junctions that make up the blood ...
