| arterial circle of cerebrum | An anastomotic "circle" of arteries (roughly pentagonal in outline) at the base of the brain, formed, sequentially and in anterior to posterior direction, by the anterior communicating artery, the two anterior cerebral, the two internal carotid, the two posterior communicating, and the two posterior cerebral arteries. Synonym: circulus arteriosus cerebri, circle of Willis. (05 Mar 2000) |

| parietal lobe of cerebrum | The middle portion of each cerebral hemisphere, separated from the frontal lobe by the central sulcus, from the temporal lobe by the lateral sulcus in front and an imaginary line projected posteriorly, and from the occipital lobe only partially by the parieto-occipital sulcus on its medial aspect. Synonym: lobus parietalis cerebri, parietal lobe. (05 Mar 2000) |
| cerebrum | <anatomy> The portion of the brain (frontal lobes) where thought and higher function reside. (12 Jan 1998) |
| cistern of great vein of cerebrum | <anatomy, vein> An expansion of the subarachnoid space extending forward between the corpus callosum and the thalamus; it encloses the internal cerebral veins which caudally join to form the vena magna cerebri (Galen's vein). Synonym: ambient cistern, Bichat's canal, Bichat's foramen, cistern of great vein of cerebrum, cisterna ambiens, cisterna superioris, cisterna venae magnae cerebri, superior cistern. (05 Mar 2000) |
| superolateral surface of cerebrum | The aspect of the cerebral hemisphere that lies in contact with the flat bones of the skull; it includes parts of the frontal, parietal, temporal, and occipital lobes. Synonym: facies superolateralis cerebri, cortical convexity, superolateral cerebral surface. (05 Mar 2000) |
| occipital lobe of cerebrum | The posterior, somewhat pyramid-shaped part of each cerebral hemisphere, demarcated by no distinct surface markings on the lateral convexity of the hemisphere from the parietal and temporal lobes, but sharply delineated from the parietal lobe by the parieto-occipital sulcus on the medial surface. Synonym: lobus occipitalis cerebri, occipital lobe. (05 Mar 2000) |
| occipital pole of cerebrum | The most posterior promontory of each cerebral hemisphere; the apex of the occipital lobe. Synonym: polus occipitalis cerebri, occipital pole. Pelvic pole, the breech end of the foetus. (05 Mar 2000) |
| temporal pole of cerebrum | The most prominent part of the anterior extremity of the temporal lobe of each cerebral hemisphere, a short distance below the fissure of Sylvius. Synonym: polus temporalis cerebri, temporal pole. (05 Mar 2000) |
| transverse fissure of cerebrum | The triangular space between the corpus callosum and fornix above and the dorsal surface of the thalamus below, which is bounded laterally by the choroid fissure of the lateral ventricle, lined by pia mater, and opens caudally into the cistern of the great cerebral vein of the subarachnoid space. Synonym: fissura transversa cerebri. (05 Mar 2000) |
| lamina terminalis of cerebrum | A thin plate passing upward from the optic chiasm and forming the rostral boundary of the third ventricle; membrane closing the rostral neuropore. Synonym: lamina terminalis cerebri, lamina cinerea, terminal plate, velum terminale. (05 Mar 2000) |
| frontal lobe of cerebrum | The portion of each cerebral hemisphere anterior to the central sulcus. Synonym: lobus frontalis cerebri, frontal lobe. (05 Mar 2000) |
| frontal pole of cerebrum | The most anterior promontory of each cerebral hemisphere. Synonym: polus frontalis cerebri, frontal pole. (05 Mar 2000) |
| lobes of cerebrum | lobi cerebri |
| longitudinal fissure of cerebrum | The deep cleft separating the two hemispheres of the cerebrum. Synonym: fissura longitudinalis cerebri, great longitudinal fissure. (05 Mar 2000) |
| lateral mammary branches of lateral cutaneous branches of intercostal nerves | Branches arising from the lateral cutaneous branches of the ventral primary rami of spinal nerves (intercostal nerves) T-3 to T-6 which run anteriorly to supply the lateral aspect of the breast. Synonym: rami mammarii laterales rami cutanei lateralis nervorum thoracicorum, rami mammarii laterales rami cutanei lateralis nervorum intercostalium, lateral mammary branches of lateral cutaneous branches of intercostal nerves.
