| lateral geniculate body | The lateral one of a pair of small oval masses that protrude slightly from the posteroinferior aspects of the thalamus; its main (dorsal) subdivision serves as a processing station in the major pathway from the retina to the cerebral cortex, receiving fibres from the optic tract and giving rise to the geniculocalcarine radiation to the visual cortex in the occipital lobe. Synonym: corpus geniculatum laterale, corpus geniculatum externum. (05 Mar 2000) |
| L-D body | The intracytoplasmic, nonflagellated leishmanial form of certain intracellular parasites, such as species of Leishmania or the intracellular form of Trypanosoma cruzi; originally used for Leishmania donovani parasites in infected spleen or liver cells in kala azar. Synonym: amastigote, L-D body. (05 Mar 2000) |
| LE body | <pathology> A globular mass of nuclear material that stains with haematoxylin, associated with lesions of systemic lupus erythematosus. (18 Nov 1997) |
| Leishman-Donovan body | The intracytoplasmic, nonflagellated leishmanial form of certain intracellular parasites, such as species of Leishmania or the intracellular form of Trypanosoma cruzi; originally used for Leishmania donovani parasites in infected spleen or liver cells in kala azar. Synonym: amastigote, L-D body. (05 Mar 2000) |
| fruiting body | <microbiology, plant biology> A macroscopic reproductive structure produced by some fungi (for example, mushrooms) and some bacteria (for example, myxobacteria). Fruiting bodies are distinct in size, shape, and colouration for each species. (13 Nov 1997) |
| Lieutaud's body | A triangular smooth area at the base of the bladder between the openings of the two ureters and that of the urethra. Synonym: trigonum vesicae, Lieutaud's body, Lieutaud's triangle, Lieutaud's trigone, vesical triangle. (05 Mar 2000) |

| loose body | A solid tissue fragment lying free in a body cavity, especially in a joint or the peritoneal cavity; e.g., joint mice, melon-seed body, rice body. (05 Mar 2000) |
| lower body negative pressure | External decompression applied to the lower body. It is used to study orthostatic intolerance and the effects of gravitation and acceleration, to produce simulated haemorrhage in physiologic research, to assess cardiovascular function, and to reduce abdominal stress during childbirth. (12 Dec 1998) |
| lung foreign body | Any object or material that does not belong in the respiratory tree. Lung foreign bodies most often result from the accidental aspiration of an object or food particle. (27 Sep 1997) |
| Luys' body | A circumscript nucleus, shaped like a biconvex lens, located in the ventral part of the subthalamus on the dorsal surface of the peduncular part of the internal capsule immediately rostral to the substantia nigra. The nucleus receives a massive topographic projection from the lateral segment of the globus pallidus, and a somatopically organised projection from the ipsilateral motor cortex; a smaller bundle of afferents from the centromedian nucleus of the thalamus terminate in the rostral part of the nucleus The subthalamic nucleus projects to both pallidal segments, to the pars reticulata of the substantia nigra, and in a small way to the ipsilateral pedunculopontine nucleus. Synonym: nucleus subthalamicus, corpus luysi, Luys' body, nucleus of Luys. (05 Mar 2000) |
| absorption cell | A small glass chamber with parallel sides, in which absorption spectra of solutions can be obtained. (05 Mar 2000) |
| acid cell | One of the cell's of the gastric glands; it lies upon the basement membrane, covered by the chief cell's, and secretes hydrochloric acid that reaches the lumen of the gland through fine intracellular and intercellular canals (canaliculi). Synonym: acid cell, oxyntic cell. (05 Mar 2000) |
