Synonym: alveololingual sulcus, gingivolingual groove, gingivolingual sulcus. (05 Mar 2000) |
| ampullary sulcus | The groove on the external surface of the ampulla of each saemicircular duct where the nerve enters the crista ampullaris. Synonym: sulcus ampullaris. (05 Mar 2000) |
| anterior intermediate sulcus | A furrow occasionally seen in the adult between the anterior median fissure and the anterior lateral sulcus of the spinal cord but usually present only in the foetus. It indicates the lateral border of the anterior corticospinal fasciculus. Synonym: anterior intermediate groove, sulcus intermedius anterior. (05 Mar 2000) |
| anterior parolfactory sulcus | A fissure marking the anterior border of the parolfactory area. Synonym: sulcus parolfactorius anterior. (05 Mar 2000) |

| calcaneal sulcus | The groove on the upper part of the calcaneus, which with a corresponding groove on the talus forms the sinus tarsi. Synonym: sulcus calcanei, calcaneal sulcus, interosseous groove. (05 Mar 2000) |
| calcarine sulcus | 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.
