| 1 | V1 | Pre-foraminal segment | Origin to the transverse foramen of C6 |
| 2 | V2 | Foraminal segment | Transverse foramen of C6 to the transverse foramen of C2 |
| 3 | V3 | Atlantic, extradural or extraspinal segment | Starts from C2, where the artery loops and turns lateral to ascend into the transverse foramen continues through C1 to pierce the dura |
| 4 | V4 | Intradural or intracranial segment | From the dura at the lateral edge of the posterior atlanto-occipital membrane to their confluence on the medulla to form the basilar artery |
