| sulcus calcarinus | A deep fissure on the medial aspect of the cerebral cortex, extending on an arched line from the isthmus of the fornicate gyrus back to the occipital pole, marking the border between the lingual gyrus below and the cuneus above it. The cortex in the depth of the sulcus corresponds to the horizontal meridian of the contralateral half of the visual field. Synonym: sulcus calcarinus, calcarine fissure, fissura calcarina, posthippocampal fissure. (05 Mar 2000) |

| 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. Synonym: sulcus cinguli, callosomarginal fissure, callosomarginal sulcus, sulcus callosomarginalis, sulcus of cingulum. (05 Mar 2000) |
| sulcus circularis insulae | A saemicircular fissure demarcating the insula from the opercula above, below, and behind. Synonym: sulcus circularis insulae, circular sulcus of Reil, limiting sulcus of Reil. (05 Mar 2000) |
| 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 coronarius | A groove on the outer surface of the heart marking the division between the atria and the ventricles. Synonym: sulcus coronarius, atrioventricular groove, atrioventricular sulcus, auriculoventricular groove, coronary 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) |
