| laminated cortex | Neocortex and allocortex. (05 Mar 2000) |

| laminated epithelial plug | An accretion of epithelia in the external auditory canal. Synonym: laminated epithelial plug. (05 Mar 2000) |
| laminated epithelium | <pathology> An epithelium composed of multiple layers of cells, only the basal layer being in contact with the basal lamina. The basal layer is of stem cells that divide to produce the cells of the upper layers, in skin, these become heavily keratinised before dying and being shed as squames. Stratified epithelia usually have a mechanical or protective role. (18 Nov 1997) |
| laminated thrombus | A thrombus formed gradually by clotting of the blood in successive layers. (05 Mar 2000) |
| lamination | 1. An arrangement in the form of plates or laminae. 2. Embryotomy by removing the foetal head in slices. (05 Mar 2000) |
| laminectomy | <procedure, surgery> A surgical procedure which is designed to relieve pressure on the spinal cord or nerve root that is being caused by a slipped or herniated disk in the lumbar spine. This procedure is also used in the treatment of spinal stenosis. This procedure includes removal of a portion of the bone comprising a vertebra. Recovery is generally 7-10 days. An alternative to this is a micro-disc surgery. (27 Jun 1999) |
| laminin | <protein> Link proteins of basal lamina, consist of an A chain (400 kD) and two B chains (200 kD). Each subunit contains at least 12 repeats of the EGF like domain. The first laminin studied was from mouse EHS cells, but it is now becoming clear that different forms of laminin occur. In laminin from placenta the A chain is replaced with merosin, in laminin found near the neuromuscular junction the B1 chain is replaced by s laminin (synapse laminin). Laminin induces adhesion and spreading of many cell types and promotes the outgrowth of neurites in culture. (27 Jun 1999) |
| laminin receptor | A receptor found in many cell types that binds laminin and has a role in cell attachment and neurite outgrowth. (05 Mar 2000) |
| laminiplantar | <ornithology> Having the tarsus covered behind with a horny sheath continuous on both sides, as in most singing birds, except the larks. Origin: Lamina + L. Planta sole of the foot. Source: Websters Dictionary (01 Mar 1998) |
| laminitis | <veterinary> Inflammation of the laminae or fleshy plates along the coffin bone of a horse; founder. Source: Websters Dictionary (01 Mar 1998) |
| laminography | See: laminagraphy. (05 Mar 2000) |
| laminotomy | An operation on one or more vertebral laminae. Synonym: rachiotomy. Origin: L. Lamina, layer, + G. Tome, incision (05 Mar 2000) |
| lamins | Proteins that form the nuclear lamina, a polymeric structure intercalated between chromatin and the inner nuclear envelope. Lamins A and C (70 and 60 kD respectively) have C terminal sequences homologous to the head and tail domains of keratins, their peptide maps are similar and significantly different from that of lamin B (67 kD), although there are some common epitopes. (18 Nov 1997) |
| lamivudine | <chemical> A reverse transcriptase inhibitor and zalcitabine analog in which a sulfur atom replaces the 3' carbon of the pentose ring. It is used to treat HIV disease. Pharmacological action: anti-HIV agents, reverse transcriptase inhibitors. Chemical name: 2(1H)-Pyrimidinone, 4-amino-1-(2-(hydroxymethyl)-1,3-oxathiolan-5-yl)-, (2R-cis)- (12 Dec 1998) |
| lammergeier | <ornithology, zoology> A very large vulture (Gypaetus barbatus), which inhabits the mountains of Southern Europe, Asia, and Northern Africa. When full-grown it is nine or ten feet in extent of wings. It is brownish black above, with the under parts and neck rusty yellow; the forehead and crown white; the sides of the head and beard black. It feeds partly on carrion and partly on small animals, which it kills. It has the habit of carrying tortoises and marrow bones to a great height, and dropping them on stones to obtain the contents, and is therefore called bonebreaker and ossifrage. It is supposed to be the ossifrage of the Bible. Synonym: bearded vulture and bearded eagle. Origin: G. Lammergeier; lamm, pl. Lammer, lamb + geier vulture.
