| 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.

| laminaria |
a rod made of kelp (seaweed) that when placed in the cervical canal absorbs moisture, swells, and gradually dilates the cervix. Used to help induce labor.
