Radicular artery
From Infogalactic: the planetary knowledge core
The posterior and anterior radicular arteries run along the posterior and anterior roots of the spinal nerves and supply them with blood.[1]
Relationship to Segmental Medullary Arteries
Radicular arteries can sometimes be replaced functionally by segmental medullary arteries.[1] However, unlike those arteries, radicular arteries do not form anastamoses with the anterior or posterior spinal arteries.[1] Radicular arteries are also generally smaller.[1]
The Artery of Adamkiewicz is sometimes called "great radicular artery of Adamkiewicz",[2] however it is in fact a segmental medullary artery.[1]
