| isthmus of limbic lobe | The narrowing of the cingulate gyrus, at its transition with the hippocampal gyrus behind and below the splenium of the corpus callosum, caused by the anterior extension of the conjoined parieto-occipital and calcarine sulci. Synonym: isthmus gyri cinguli, isthmus of gyrus fornicatus, isthmus of limbic lobe. (05 Mar 2000) |

| occipital lobe | House the visual interpretation centres. (27 Sep 1997) |
| occipital lobe epilepsy | A localization-related epilepsy where seizures originate from the occipital lobe. Symptoms commonly include visual abnormalities during seizures. (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) |
| optic lobe | In invertebrate zoology, a lateral lobe of the forebrain in certain arthropods. In vertebrate zoology, either of the corpora bigemina of lower vertebrates. (12 Dec 1998) |
| temporal lobe | A lobe of the brain which is located laterally and below the cerebrum. Contains auditory and receptive areas. (27 Sep 1997) |
| temporal lobe epilepsy | Seizures with elaborate and multiple sensory, motor, and/or psychic components. A common feature is the clouding of consciousness and amnesia for the event. Some clinical manifestations may include more complex behaviours like burst of anger, emotional outbursts, fear or automatisms. The EEG often reveals spike discharges in the temporal lobe during sleep. (27 Sep 1997) |
| ear lobe | The lowest part of the auricle; it consists of fat and fibrous tissue not reinforced by the auricular cartilage. Synonym: lobulus auriculae, lobule of auricle. (05 Mar 2000) |
| ear lobe crease | A diagonal crease found on one or both earlobes with a possible connection to coronary heart disease in males. (05 Mar 2000) |
| epilepsy, temporal lobe | Epileptic seizures characterised by simple partial seizures, complex partial seizures, and secondary generalised seizures, or combinations of these. Seizures may present with autonomic and/or psychic symptoms and certain sensory phenomena such as olfactory and auditory. most common is an epigastric rising sensation. Some seizures may begin with motor arrest and continue with oro-alimentary automatisms (with other automatisms following). Attacks are followed by amnesia and recovery is gradual. Usually, there is a history of febrile seizures in the individual or a history of seizures in the family. Seizures occur in clusters, randomly, or at intervals. (12 Dec 1998) |
| falciform lobe | cingulate gyrus |
| upper lobe of lung | The lobe of the right lung that lies above the oblique and horizontal fissures and includes the apical, posterior and anterior bronchopulmonary segments; in the left lung, the lobe lies above the oblique fissure and contains the apicoposterior, anterior, superior lingular and inferior lingular segments. Synonym: lobus superior pulmonis, upper lobe of lung. (05 Mar 2000) |
| upper/lower lobe predominance | <radiology> Upper lobe, usually site of greatest disease due to poorer clearance, bronchogenic carcinoma, pneumoconioses, histiocytosis X, sarcoidosis, ankylosing spondylitis, lower lobe, scleroderma (12 Dec 1998) |
| flocculonodular lobe | The small posterior and inferior subdivision of the cerebellar cortex that borders the line of attachment of the choroid roof of the rhomboid fossa, and consists of the left and right flocculus together with the unpaired nodulus (the most posterior of the folia composing the vermis cerebelli). Its major afferent connections come from the vestibular nuclei and directly from the vestibular nerve; it projects largely to the vestibular nuclei, directly and by way of the fastigial nucleus. (05 Mar 2000) |
| left duct of caudate lobe | A tributary to the left hepatic duct draining bile from the left half of the caudate lobe. Synonym: ductus lobi caudati sinister. (05 Mar 2000) |
