| atlanto-occipital articulation | <anatomy> A condylar synovial joint between the superior articular facets of the atlas and the condyles of the occipital bone. Synonym: articulatio atlanto-occipitalis, atlanto-occipital articulation. (05 Mar 2000) |
| atlanto-occipital joint | <anatomy> A condylar synovial joint between the superior articular facets of the atlas and the condyles of the occipital bone. Synonym: articulatio atlanto-occipitalis, atlanto-occipital articulation. (05 Mar 2000) |
| atlanto-occipital membrane | <anatomy> More specifically see: anterior atlanto-occipital membrane, posterior atlanto-occipital membrane. (05 Mar 2000) |

| auricular branch of occipital artery | <anatomy, artery> Distribution, posterior auricle; anastomosis, posterior auricular artery. Synonym: ramus auricularis arteriae occipitalis. (05 Mar 2000) |
| calcarine branch of medial occipital artery | <anatomy, artery> Branch of medial occipital artery which runs in relationship to the calcarine sulcus. Synonym: ramus calcarinus arteriae occipitalis medialis, arteria calcarina, calcarine artery. (05 Mar 2000) |
| parieto-occipital | Relating to the parietal and occipital bones or to the parts of the cerebral cortex corresponding thereto. (05 Mar 2000) |
| parieto-occipital artery | <anatomy, artery> The largest cortical branch of the pericallosal artery supplying the medial and superolateral surface of the parietal lobe posterior to the paracentral lobule; rarely does it extend to supply part of the occipital lobe.

| parieto-occipital fissure | A very deep, almost vertically oriented fissure on the medial surface of the cerebral cortex, marking the border between the parietal lobe and the cuneus of the occipital lobe; its lower part curves forward and fuses with the anterior extent of the calcarine fissure (sulcus calcarinus); the great depth of this combined fissure causes a bulge in the medial wall of the occipital horn of the lateral ventricle, the calcar avis. Synonym: sulcus parieto-occipitalis, fissura parietooccipitalis, parieto-occipital fissure. (05 Mar 2000) |
