| Posterolateral sulcus of spinal cord | |
| Latin: | sulcus posterolateralis medullae spinalis |
On either side of the posterior median sulcus of the spinal cord, and at a short distance from it, the posterior nerve roots are attached along a vertical furrow named the posterolateral sulcus. The portion of the medulla spinalis which lies between this and the posterior median sulcus is named the posterior funiculus.
