Arteria radicularis anterioris
Read moreQuick Facts
Origin: Radicular artery.
Course: Accompany the anterior roots of the spinal cord through the intervertebral foramina.
Branches: None.
Supplied Structures: Anterior roots of spinal cord.
Origin
After the radicular arteries arise from the lateral spinal branches of the vertebral, ascending cervical, intercostal, subcostal, and lumbar arteries, they divide into anterior and posterior branches.
Course
The anterior radicular arteries pass medially to enter the intervertebral foramina at each vertebral level. They accompany the anterior roots of the spinal cord. Most of the anterior radicular arteries are too small to reach as far as the spinal cord itself, or terminate in the pial plexus (Standring, 2020).
Branches
There are no named branches.
Supplied Structures
The anterior radicular arteries supply the anterior roots of the spinal cord.
