| lobulus fusiformis | An extremely long convolution extending lengthwise over the inferior aspect of the temporal and occipital lobes, demarcated medially by the collateral sulcus from the lingual gyrus and the anterior part of the parahippocampal gyrus, laterally by the inferior temporal sulcus from the inferior temporal gyrus. Synonym: gyrus occipitotemporalis lateralis, gyrus fusiformis, lateral occipitotemporal gyrus, lobulus fusiformis. (05 Mar 2000) |
| lobulus gracilis | The anterior portion of the posteroinferior lobule of the cerebellum, the posterior portion being the semilunar lobule inferior; the two correspond to the tuber of the vermis. Synonym: lobulus gracilis, slender lobule. (05 Mar 2000) |
| lobulus hepatis | The conceptual polygonal histologic unit of the liver consisting of masses of liver cells arranged around a central vein, a terminal branch of one of the hepatic veins; at the periphery are located preterminal and terminal branches of the portal vein, hepatic artery, and bile duct, hepatic lobules have anatomical reality in the pig liver or pathologically in humans, when fibrous septa are present.
