| norma occipitalis | The outline of the skull viewed from behind. Synonym: norma posterior. (05 Mar 2000) |
| sulcus arteriae occipitalis | A narrow groove medial to the mastoid notch of the temporal bone that lodges the occipital artery. Synonym: sulcus arteriae occipitalis, sulcus of occipital artery. (05 Mar 2000) |
| sulcus occipitalis lateralis | One of several variable sulci on the lateral aspect of the occipital lobe of each cerebral hemisphere, bounding the lateral occipital convolutions. Synonym: sulcus occipitalis lateralis. (05 Mar 2000) |
| sulcus occipitalis superior | One of several small and variable sulci bordering the superior occipital gyri on the upper aspect of the occipital lobe of the cerebrum. Synonym: sulcus occipitalis superior. (05 Mar 2000) |

| trachelo-occipitalis | Archaic term for semispinalis capitis muscle. (05 Mar 2000) |
| fissura petro-occipitalis | A fissure between the petrous part of the temporal bone and the basilar part of the occipital bone that extends anteromedially from the jugular foramen; includes the jugular foramem (at its posterior end). Synonym: fissura petro-occipitalis, Ecker's fissure. (05 Mar 2000) |
