| middle temporal sulcus | The sulcus between the middle temporal gyrus and inferior temporal gyrus. Synonym: sulcus temporalis medius. (05 Mar 2000) |
|---|---|
| collateral sulcus | 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) |
| Monro's sulcus | 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) |
| coronary sulcus | 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) |
| costophrenic sulcus | The recess between the ribs and the lateral-most portion of the diaphragm, partially occupied by the most caudal part of the lung; seen on radiographs as the costophrenic angle. (05 Mar 2000) |
| postcentral sulcus | The sulcus that demarcates the postcentral gyrus from the superior and inferior parietal lobules. Synonym: sulcus postcentralis. (05 Mar 2000) |
| habenular sulcus | A small groove located between the habenular trigone and the adjacent dorsal thalamus. (05 Mar 2000) |
| posterolateral sulcus | 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) |
| preauricular sulcus | A groove on the pelvic surface of the ilium just lateral to the auricular surface; it is more pronounced in the female. Synonym: paraglenoid groove, paraglenoid sulcus, preauricular sulcus, sulcus paraglenoidalis. (05 Mar 2000) |
| precentral sulcus | An interrupted fissure anterior to and in general parallel with the central sulcus, marking the anterior border of the precentral gyrus. Synonym: sulcus precentralis, sulcus verticalis. (05 Mar 2000) |
| prechiasmatic sulcus | The groove on the upper surface of the sphenoid bone running transversely between the optic canals bounded anteriorly by the sphenoidal limbus and posteriorly by the tuberculum sellae; forms in relationship to the optic chiasm. Synonym: sulcus prechiasmatis, chiasmatic sulcus, optic groove, prechiasmatic sulcus. (05 Mar 2000) |
| sagittal sulcus | The groove in the midline of the inner table of the calvaria lodging the superior sagittal sinus. Synonym: sulcus sinus sagittalis superioris, sagittal groove, sagittal sulcus, superior longitudinal sulcus. (05 Mar 2000) |
| scleral sulcus | A slight groove on the external surface of the eyeball indicating the line of union of the sclera and cornea or limbus of cornea. Synonym: sulcus sclerae, sulcus of sclera. (05 Mar 2000) |
| hippocampal sulcus | 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) |
| pulmonary sulcus | The deep recess on either side of the vertebral column formed by the posterior sweep of the curvature of the ribs. Synonym: sulcus pulmonalis, pulmonary sulcus. (05 Mar 2000) |
