| lingula of cerebellum | A tongue-shaped sequence of flattened cerebellar folia forming the anterior (or superior) extreme of the cerebellar vermis, extending forward on the surface of the superior medullary velum between the two emerging superior cerebellar peduncles. Synonym: lingula cerebelli, lingua cerebelli, tongue of cerebellum. (05 Mar 2000) |

| ansiform lobule | Comprises the greater part of the hemisphere of the cerebellum; its superior and inferior surfaces are separated by the horizontal fissure into major parts known as crus I (superior semilunar lobule) and crus II (inferior semilunar lobule). (05 Mar 2000) |
| anterior lunate lobule | The part of the superior surface of the cerebellar hemisphere lying rostral to the horizontal fissure, and adjoining the folium of the vermis. Synonym: lobulus semilunaris superior, anterior lunate lobule, crus I. (05 Mar 2000) |
| biventer lobule | A lobule on the undersurface of each cerebellar hemisphere, divided by a curved sulcus into a lateral and medial portion; it corresponds to the pyramid of the vermis. Synonym: lobulus biventer, biventral lobule, cuneiform lobe, lobulus biventralis, lobulus cuneiformis. (05 Mar 2000) |
| biventral lobule | A lobule on the undersurface of each cerebellar hemisphere, divided by a curved sulcus into a lateral and medial portion; it corresponds to the pyramid of the vermis. Synonym: lobulus biventer, biventral lobule, cuneiform lobe, lobulus biventralis, lobulus cuneiformis. (05 Mar 2000) |
| paracentral lobule | A division of the medial aspect of the cerebral cortex, lying above the singulate sulcus and bounded by the precentral sulcus in front and the marginal part of the cingulate sulcus behind. Synonym: lobulus paracentralis. (05 Mar 2000) |
| renal cortical lobule | One of the subdivisions of the kidney, consisting of a medullary ray and that portion of the convoluted port (renal corpuscles and convoluted tubules) associated with its collecting duct. Synonym: lobulus corticalis renalis, renal cortical lobule, renculus, reniculus, renunculus. (05 Mar 2000) |
| respiratory lobule | The part of the airway consisting of a respiratory bronchiole and all of its branches. Synonym: primary pulmonary lobule, respiratory lobule. (05 Mar 2000) |
| gracile lobule | 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) |
| convoluted part of kidney lobule | Proximal and distal convoluted tubules and the associated renal corpuscles supplied by branches of the interlobular arteries. Synonym: labyrinthus, pars convoluta lobuli corticalis renis, labyrinth, Ludwig's labyrinth, renal labyrinth. (05 Mar 2000) |
| portal lobule of liver | A conceptual unit of the liver, emphasizing its exocrine function in bile secretion, which comprises a roughly triangular shaped cross-sectional area with a portal canal at its centre and three or more venae centrales hepatis at its periphery. (05 Mar 2000) |
| posterior lunate lobule | The part of the superior surface of the cerebellar hemisphere lying behind the horizontal fissure. Synonym: lobulus semilunaris inferior, crus II, posterior lunate lobule. (05 Mar 2000) |
| primary pulmonary lobule | The part of the airway consisting of a respiratory bronchiole and all of its branches. Synonym: primary pulmonary lobule, respiratory lobule. (05 Mar 2000) |
| hepatic lobule | 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. Synonym: lobulus hepatis. (05 Mar 2000) |
| secondary pulmonary lobule | A pyramidal mass of lung tissue whose sides are bounded by the incomplete interlobular connective tissue septa and whose base, which is 1 to 2 cm in diameter, usually faces the pleural surface of the lung; lobule's that occupy a more central position in the lung are not well defined and are considered to consist of three to five pulmonary acini with proximate terminal bronchioles.
