What is the function of the anterior spinal artery?

What arteries form the anterior spinal artery?

These branches are derived from the vertebral artery, the ascending cervical artery, a branch of the inferior thyroid artery in the neck, the intercostal arteries in the thorax, and from the lumbar artery, iliolumbar artery and lateral sacral arteries in the abdomen and pelvis.

Is central cord syndrome permanent?

There is no cure for central cord syndrome although some people recover near-normal function. There is no standard course of treatment, although drug therapy, surgery, and rest are often part of the program.

What stops blood flow to the brain?

A thrombotic stroke occurs when a blood clot, called a thrombus, blocks an artery to the brain and stops blood flow. An embolic stroke occurs when a piece of plaque or thrombus travels from its original site and blocks an artery downstream.

What is the anterior spinal artery?

The anterior spinal artery is the major blood supply for the spinal cord. It descends from the level of the foramen magnum along the anterior surface of the spinal cord. As it continues to descend, the artery receives communication with other branches that enter the spinal canal through the intervertebral foramen.

How many vertebral arteries do you have?

Here’s the vertebral artery. The two vertebral arteries pass through these openings in each vertebra. After passing through the transverse process of the atlas, the artery turns backwards, and then medially, to pass through the atlanto-occipital membrane and the dura, just below the foramen magnum, which is here.

What arteries supply the spinal cord?

The main blood supply to the spinal cord is via the single anterior spinal artery (ASA) and the two posterior spinal arteries (PSA). The anterior spinal artery is formed by the vertebral arteries which originate from the first part of the subclavian artery.

Which artery Vascularizes a root of a spinal nerve?

radiculomedullary arteries, which are the only arteries that truly vascularize the spinal cord by joining and supporting the three longitudinal vascular channels as well as providing blood supply to the ventral and dorsal roots.

How many arteries supply the spinal cord?

The cord is dependent upon three longitudinal arterial trunks or channels. The anterior and posterior spinal artery longitudinally runs along the whole spinal cord and often anastomose with each other forming plexuses.
