| sulcus hippocampi | A shallow groove between the dentate gyrus and the parahippocampal gyrus; the remains of a fissure extending deep into the hippocampus between Ammon's horn and the dentate gyrus which becomes obliterated during foetal development. Synonym: sulcus hippocampi, dentate fissure, fissura dentata, fissura hippocampi, hippocampal fissure. (05 Mar 2000) |

| sulcus hypothalamicus | A groove in the lateral wall of the third ventricle on either side leading from the interventricular foramen to the aditus ad aqueductum cerebri; the sulcus-demarcated boundary between dorsal thalamus and hypothalamus. Synonym: sulcus hypothalamicus, Monro's sulcus. (05 Mar 2000) |
| sulcus infraorbitalis | A gradually deepening groove on the orbital surface of the maxilla, which leads to the infraorbital canal. Synonym: sulcus infraorbitalis. (05 Mar 2000) |
| sulcus infrapalpebralis | The hollow or furrow below the lower eyelid. Synonym: sulcus infrapalpebralis. (05 Mar 2000) |
| sulcus intermedius posterior | A longitudinal furrow between the posterior median and the posterolateral sulci of the spinal cord in the cervical region, marking the gracile fasciculus from the cuneate fasciculus. Synonym: sulcus intermedius posterior, posterior intermediate groove. (05 Mar 2000) |
| sulcus intertubercularis | A furrow running down the shaft of the humerus between the two tubercles, lodging the tendon of the long head of the biceps, and giving attachment in its floor to the latissimus dorsi muscle. Synonym: sulcus intertubercularis, bicipital groove, intertubercular sulcus. (05 Mar 2000) |
| sulcus interventricularis cordis | See: anterior interventricular groove, posterior interventricular groove. (05 Mar 2000) |
| sulcus interventricularis posterior | A groove on the diaphragmatic surface of the heart, marking the location of the septum between the two ventricles. Synonym: sulcus interventricularis posterior, crena cordis. (05 Mar 2000) |
| sulcus intragracilis | A fissure between the gracilis minor and gracilis posterior lobuli of the cerebellum. Synonym: sulcus intragracilis. (05 Mar 2000) |
| sulcus intraparietalis | A horizontal sulcus extending back from the postcentral sulcus over some distance, then dividing perpendicularly into two branches so as to form, with the postcentral sulcus, a figure H. It divides the parietal lobe into superior and inferior parietal lobules. Synonym: sulcus intraparietalis, interparietal sulcus, intraparietal sulcus of Turner, Turner's sulcus. (05 Mar 2000) |
| sulcus lacrimalis | The groove in the nasal surface of the maxilla which, together with the lacrimal bone, forms the fossa for the lacrimal sac. Synonym: sulcus lacrimalis. (05 Mar 2000) |
| sulcus lateralis cerebri | The deepest and most prominent of the cortical fissures, extending from the anterior perforated substance first laterally at the deep incisure between the frontal and temporal lobes, then back and slightly upward over the lateral aspect of the cerebral hemisphere, with the superior temporal gyrus as its lower bank, the insula forming its greatly expanded floor. Two short side branches, the ramus anterior and ramus ascendens, divide the inferior frontal gyrus into an orbital part, triangular part, and opercular part. Synonym: sulcus lateralis cerebri, fissura cerebri lateralis, lateral cerebral fissure, sylvian fissure, fissure of Sylvius. (05 Mar 2000) |
| sulcus lateralis posterior | A longitudinal furrow on either side of the posterior median sulcus of the spinal cord marking the line of entrance of the posterior nerve roots. Synonym: sulcus lateralis posterior, posterolateral groove. (05 Mar 2000) |
| sulcus limitans | The medial longitudinal groove on the inner surface of the neural tube separating the alar and basal plates. Synonym: sulcus limitans. (05 Mar 2000) |
| sulcus limitans fossae rhomboideae | A lateral groove running the whole length of the floor of the rhomboid fossa on either side of the midline, representing the remains of the sulcus demarcating the alar (dorsal) from the basal (ventral) plate of the embryonic rhombencephalon. Synonym: sulcus limitans fossae rhomboideae. (05 Mar 2000) |
