| 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, frontal lobe | Epileptic seizures arising from the frontal lobe characterised by simple partial, complex partial, secondary generalised seizures, or combinations of these. The seizures, which are short in duration, may occur several times a day, mostly during sleep. Affected individuals usually have prominent motor manifestations which are tonic or postural, complex gestational automatisms at the onset, and fall to the ground when the discharge is bilateral. Status epilepticus is a frequent complication. (12 Dec 1998) |
| 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) |
| frontal lobe | The frontal lobes are responsible for higher cognitive thought processes. (27 Sep 1997) |
| frontal lobe epilepsy | A localization-related epilepsy with seizures originating in the frontal lobe. A variety of clinical syndromes exist depending on the exact localization of seizures and clinical semiology of the seizure type. Frontal lobe epilepsies have been divided into several specific syndromes including the syndrome of supplementary motor seizures, cingulate seizures, anterior frontal polar region seizures, orbital frontal seizures, dorsolateral seizures, opercular seizures, and seizures of the motor cortex. (05 Mar 2000) |
| frontal lobe of cerebrum | The portion of each cerebral hemisphere anterior to the central sulcus. Synonym: lobus frontalis cerebri, frontal lobe. (05 Mar 2000) |
| limbic lobe | As originally defined by P. Broca: the nearly closed ring of the brain structures surrounding the hilus, or margin, of the cerebral hemisphere of mammals; it is composed of the fornicate gyrus (cingulate gyrus and parahippocampal gyrus), the hippocampus, and the amygdala. See: limbic system. (05 Mar 2000) |
| lingual lobe | A U-or W-shaped ridge at the base of the lingual surface of the crown of the upper incisors and cuspid teeth, the lateral limbs running for a short distance along the linguoproximal line angles, the central portion just above the gingiva. Synonym: cingulum dentis, basal ridge, lingual lobe. (05 Mar 2000) |
| lobe | <anatomy> A more or less well defined portion of any organ, especially of the brain, lungs and glands. Lobes are demarcated by fissures, sulci, connective tissue and by their shape. Origin: L. Globus, from Gr. Lobos (18 Nov 1997) |
