| nervus occipitalis major | <anatomy, nerve> Medial branch of the dorsal primary ramus of the second cervical nerve; sends branches to the semispinalis capitis and multifidus cervicis, but is mainly cutaneous, supplying the back part of the scalp. Synonym: nervus occipitalis major. (05 Mar 2000) |
| nervus occipitalis minor | Synonym: lesser occipital nerve. (05 Mar 2000) |
| nervus occipitalis tertius | <anatomy, nerve> Medial branch of the dorsal primary ramus of the third cervical nerve; this is usually joined with the greater occipital, but may exist as an independent nerve supplying cutaneous branches to the scalp and nucha. Synonym: nervus occipitalis tertius. (05 Mar 2000) |
| 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) |

| sulcus parieto-occipitalis | 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) |
| synchondrosis petro-occipitalis | Fibrocartilage filling the petro-occipital fissure. Synonym: synchondrosis petro-occipitalis. (05 Mar 2000) |
| synchondrosis spheno-occipitalis | Cartilaginous union between the body of the sphenoid and the basilar portion of the occipital; it fuses by the twentieth year; incorrectly called spheno-occipital suture. Synonym: synchondrosis spheno-occipitalis, spheno-occipital joint, spheno-occipital suture. (05 Mar 2000) |
| incisura jugularis ossis occipitalis | The notch in the occipital bone which forms one boundary of the jugular foramen. Synonym: incisura jugularis ossis occipitalis. (05 Mar 2000) |
| occipitalis | <anatomy> The posterior belly of the occipitofrontalis muscle. See: occipitofrontalis muscle. Synonym: venter occipitalis musculi occipitofrontalis, occipitalis muscle. (05 Mar 2000) |
