dictionary help| parieto-occipital sulcus | medical dictionary |
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.
Synonyms: sulcus parieto-occipitalis, fissura parietooccipitalis, parieto-occipital fissure.
