Origin
The ascending cervical arteries give rise to spinal branches.
Course
The spinal branches of the ascending cervical arteries enter the cervical intervertebral foramina, accompanied by the cervical spinal nerves.
Branches
The spinal branches of the ascending cervical artery give rise to prelaminar, radicular, and postcentral branches.
Supplied Structures
The spinal branches of the ascending cervical artery supply the cervical vertebrae, the periphery of the intervertebral discs, as well as the adjacent dura and epidural tissue. The small radicular arteries supply the anterior and posterior roots of the spinal cord (including the spinal, or dorsal root, ganglion). When the radicular arteries are enlarged (segmental medullary arteries), they contribute to the anterior and posterior spinal arteries, which supply the spinal cord (Standring, 2020; Jones et al., 2013).
