What areas of the spinal cord are supplied by the posterior spinal artery?
The posterior spinal arteries are paired arteries that run dorsolateral to the spinal cord.
They extend the length of the cord and supply the posterior third of the cord through circumflex and penetrating vessels.
Occlusion of one of these arteries results in ipsilateral deficits in vibratory and proprioceptive sensation below the site of occlusion.
