| lobus appendicularis | An occasional tongue-like process extending downward from the right lobe of the liver lateral to the gallbladder; a similar process may, though rarely, extend from the left lobe. Synonym: lobus appendicularis, lobus linguiformis. (05 Mar 2000) |

| lobus azygos | A small accessory lobe sometimes found on the apex of the right lung; separated from the rest of the upper lobe by a deep groove lodging the azygos vein. Synonym: lobus azygos. (05 Mar 2000) |
| lobus caudatus | A small lobe of the liver situated posteriorly between the sulcus for the vena cava and the fissure for the ligamentum venosum. Synonym: caudate lobe, Spigelius' lobe. Lobi cerebri, the major divisions of the cerebral hemisphere; they include the frontal, parietal, temporal, and occipital lobes, named for the overlying bones of the skull. Synonym: lobes of cerebrum. Lobus clivi, the clivus monticuli and the posterior crescentic lobules of the cerebellum considered as one lobe. (05 Mar 2000) |
| lobus dexter | The right subdivision of several glands, e.g., prostate, thyroid, thymus. Synonym: lobus dexter. (05 Mar 2000) |
| lobus falciformis | cingulate gyrus |
| lobus frontalis cerebri | The portion of each cerebral hemisphere anterior to the central sulcus. Synonym: lobus frontalis cerebri, frontal lobe. (05 Mar 2000) |
| lobus glandularis hypophyseos | It consists of the distal part, intermediate part, and infundibular part. See: hypophysis. Synonym: lobus anterior hypophyseos, anterior lobe of hypophysis, glandular lobe of hypophysis, lobus glandularis hypophyseos. (05 Mar 2000) |
| lobus hepatis dexter | The largest lobe of the liver, separated from the left lobe above and in front by the falciform ligament and from the caudate and quadrate lobes by the sulcus for the vena cava and the fossa for the gallbladder; it contains two segments, anterior and posterior. Synonym: lobus hepatis dexter. (05 Mar 2000) |
| lobus hepatis sinister | It is separated from the right lobe above and in front by the falciform ligament, and from the quadrate and caudate lobes by the fissure for the ligamentum teres and the fissure for the ligamentum venosum; the distribution of the portal vein, hepatic artery, and bile ducts does not correspond to the gross lobar divisions of the liver. It contains two segments, superior and inferior. Synonym: lobus hepatis sinister. (05 Mar 2000) |
| lobus inferior pulmonis | It is located below and behind the oblique fissure and contains five bronchopulmonary segments: superior, medial basal, anterior basal, lateral basal, and posterior basal. Synonym: lobus inferior pulmonis, lower lobe of lung. (05 Mar 2000) |
| lobus linguiformis | An occasional tongue-like process extending downward from the right lobe of the liver lateral to the gallbladder; a similar process may, though rarely, extend from the left lobe. Synonym: lobus appendicularis, lobus linguiformis. (05 Mar 2000) |
| lobus medius prostatae | The portion of the prostate lying between the urethra and the ejaculatory ducts; indistinct unless hypertrophied. Synonym: lobus medius prostatae, Morgagni's caruncle. (05 Mar 2000) |
| lobus medius pulmonis dextri | It is located anteriorly between the horizontal and oblique fissures and includes lateral and medial bronchopulmonary segments. Synonym: lobus medius pulmonis dextri. (05 Mar 2000) |
| lobus nervosus | The bulbous part of the neurohypophysis attached to the hypothalamus by the infundibulum. It is composed of pituicytes, blood vessels, and terminals of nerve fibres from the supraoptic and paraventricular nuclei. Synonym: lobus nervosus, nervous lobe. (05 Mar 2000) |
| lobus occipitalis cerebri | 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) |
