Origin
The lateral sacral arteries give rise to spinal branches.
Course
The spinal branches of the lateral sacral arteries enter the first or second anterior sacral foramina and ascend along the cauda equina.
Branches
There are no named branches; however, the spinal branches of the lateral sacral arteries anastomose with those of the lower lumbar and iliolumbar arteries and contribute to the anastomotic ansa around the conus medullaris of the spinal cord (Jones et al., 2013).
Supplied Structures
The spinal branches of the lateral sacral arteries supply the lumbosacral junction, as well as the cauda equina and the conus medullaris of the spinal cord (Standring, 2020).
