The Telencephalon 端脑 山东大学医学院解剖教研室 李振华 General Appearance of Cerebrum The telencephalon consists of right and left cerebral hemisphere, partially separated by cerebral longitudinal fissure大脑纵裂 In the depths of the fissure, the corpus callosum 胼胝体connects the hemispheres across the midline The cerebral transverse fissure intervenes between the hemispheres and the cerebellum Each hemisphere has three surfaces: superolateral, medial and inferior Main Sulci Three principal sulci Central sulcus 中央沟 Lateral sulcus 外侧沟 Parietooccipital sulcus 顶枕沟 Lobes of Cerebral Hemisphere Five lobes Frontal lobe 额叶 Parietal lobe 顶叶 Temporal lobe 颞叶 Occipital lobe 枕叶 Insular lobe 岛叶 Sulci and gyri of frontal lobe Precentral sulcus 中央前沟 Precentral gyrus 中央前回 Superior frontal sulcus 额上沟 Inferior frontal sulcus 额下沟 Superior frontal gyrus 额上回 Middle frontal gyrus 额中回 Inferior frontal gyrus 额下回 Sulci and gyri of frontal lobe Sulci and Gyri of Parietal Lobe Postcentral sulcus 中央后沟 Postcentral gyrus 中央后回 Intraparietal sulcus 顶内沟 Superior parietal lobule 顶上小叶 Inferior parietal lobule 顶下小叶 Supramarginal gyrus 缘上回 Angular gyrus 角回 Sulci and Gyri of Parietal Lobe Sulci and Gyri of Temporal Lobe Superior temporal sulcus 颞上沟 Inferior temporal sulcus 颞下沟 Superior temporal gyrus 颞上回 Middle temporal gyrus 颞中回 Inferior temporal gyrus 颞下回 Transverse temporal gyri 颞横回 Sulci and Gyri of Temporal Lobe Sulci and Gyri of Temporal Lobe Sulci and gyri of Superolateral surface Sulci and Gyri of Medial Surface Corpus callosum 胼胝体 Callosal sulcus 胼胝体沟 Cingulate gyrus 扣带回 Cingulate sulcus 扣带沟 Marginal ramus 缘支 Paracentral lobule 中央旁小叶 Calcarine sulcus 距状沟 Cuneus 楔叶 Lingual gyrus 舌回 Sulci and Gyri of Medial Surface Sulci and Gyri of Inferior Surface Olfactory bulb 嗅球 Olfactory tract 嗅束 Olfactory trigone 嗅三角 Anterior perforated substance 前穿质 Collateral sulcus 侧副沟 Occipitotemporal sulcus 枕颞沟 Medial occipitotemporal gyrus 枕颞内侧回 Lateral occipitotemporal gyr
