| sulcus callosomarginalis | A fissure on the mesial surface of the cerebral hemisphere, bounding the upper surface of the cingulate gyrus (callosal convolution); the anterior portion is called the pars subfrontalis; the posterior portion which curves up to the superomedial margin of the hemisphere and borders the paracentral lobule posteriorly, the pars marginalis. Synonym: sulcus cinguli, callosomarginal fissure, callosomarginal sulcus, sulcus callosomarginalis, sulcus of cingulum. (05 Mar 2000) |

| sulcus caroticus | The groove on the body of the sphenoid bone in which the internal carotid artery lies in its course through the cavernous sinus. Synonym: sulcus caroticus, carotid sulcus, cavernous groove. (05 Mar 2000) |
| sulcus carpi | The concavity on the anterior surface of the arch formed by the carpal bones. Synonym: sulcus carpi, carpal canal. (05 Mar 2000) |
| sulcus centralis | A double-S-shaped fissure extending obliquely upward and backward on the lateral surface of each cerebral hemisphere at the boundary between frontal and parietal lobes. Synonym: sulcus centralis, fissure of Rolando. (05 Mar 2000) |
| sulcus cinguli | A fissure on the mesial surface of the cerebral hemisphere, bounding the upper surface of the cingulate gyrus (callosal convolution); the anterior portion is called the pars subfrontalis; the posterior portion which curves up to the superomedial margin of the hemisphere and borders the paracentral lobule posteriorly, the pars marginalis.

| sulcus collateralis | A long, deep sagittal fissure on the undersurface of the temporal lobe, marking the border between the fusiform gyrus laterally and the hippocampal and lingual gyri medially; the great depth of the collateral sulcus results in a bulging of the floor of the occipital and temporal horn of the lateral ventricle, the collateral eminence. Synonym: sulcus collateralis, sulcus occipitotemporalis, collateral fissure, fissura collateralis, occipitotemporal sulcus. (05 Mar 2000) |

| sulcus corporis callosi | The fissure between the corpus callosum and the cingulate gyrus. Synonym: sulcus corporis callosi, callosal sulcus. (05 Mar 2000) |
| sulcus costae | A groove in the lower inner border of the rib, lodging the intercostal vessels and nerve. Synonym: sulcus costae, subcostal groove. (05 Mar 2000) |
| sulcus costae arteriae subclaviae | <anatomy, artery> A groove immediately posterior to the scalene tubercle on the upper surface of the first rib across which the subclavian artery passes. Synonym: sulcus costae arteriae subclaviae. (05 Mar 2000) |
| sulcus cruris helicis | A transverse fissure on the cranial surface of the auricle corresponding to the crus of the helix. Synonym: sulcus cruris helicis. (05 Mar 2000) |
| sulcus ethmoidalis | A groove on the inner surface of each nasal bone, lodging the external nasal branch of the anterior ethmoid nerve. Synonym: sulcus ethmoidalis. (05 Mar 2000) |
| sulcus fimbriodentatus | A shallow groove between the fimbria and the dentate gyrus of the hippocampus. Synonym: sulcus fimbriodentatus. (05 Mar 2000) |
| sulcus for middle temporal artery | <anatomy, artery> A vertical groove located above the external acoustic meatus on the external surface of the squamous part of the temporal bone. Synonym: sulcus arteriae temporalis mediae, sulcus for middle temporal artery. (05 Mar 2000) |
