| neural spine | The middle point of the neural arch of the typical vertebra, represented by the spinous process. (05 Mar 2000) |

| neural tube | <embryology> The progenitor of the central nervous system. See: neural plate, neurulation. (18 Nov 1997) |
| neural tube defect | <neurology, paediatrics> Abnormal development during embryonic life of the neural tube producing congenital malformations of the nervous system due to closure failure of the neural tube. The structure gives rise to the central nervous system (the brain and spinal cord), and failure to close results in anencephaly (absence of the cranial vault and absence of most or all of the cerebral hemispheres of the brain) and spina bifida or meningomyelocele (open spina with exposure and protusion of the spinal cord). The risk of neuroal tube defects can be decreased by the mother taking folic acid during pregnancy. (04 Jul 1999) |
| dorsal plate of neural tube | The thin layer of the embryonic neural tube connecting the alar plate's dorsally. Synonym: dorsal plate of neural tube. (05 Mar 2000) |
| dorsolateral plate of neural tube | The dorsal division of the lateral walls of the neural tube in the embryo; it gives rise to neurons relaying afferent impulses to higher centres; in the adult such neurons compose the sensory nuclei of the spinal cord and brainstem. Synonym: lamina alaris, alar plate of neural tube, dorsolateral plate of neural tube, lamina dorsalis, wing plate. (05 Mar 2000) |
| bone marrow transplantation | <oncology, procedure> Treatment in which healthy bone marrow replaces bone marrow that has been affected by a disease or by treatment for a disease. Acronym: BMT (12 May 1997) |
| bone transplantation | The grafting of bone from a donor site to a recipient site. (12 Dec 1998) |
| brain tissue transplantation | Transference of brain tissue, either from a foetus or from a born individual, between individuals of the same species or between individuals of different species. (12 Dec 1998) |
| cardiopulmonary transplantation | The simultaneous, or near simultaneous, transference of heart and lungs from one human or animal to another. (12 Dec 1998) |
| pancreas transplantation | The transference of a pancreas from one human or animal to another. (12 Dec 1998) |
| pancreaticoduodenal transplantation | A technically feasible transplantation including both the duodenum and pancreas. (05 Mar 2000) |
| renal transplantation | Transplantation of a kidney from a compatible donor to restore kidney function in a recipient suffering from renal failure. (05 Mar 2000) |
| cell transplantation | Transference of cells within an individual, between individuals of the same species, or between individuals of different species. (12 Dec 1998) |
| peripheral blood stem cell transplantation | A procedure that is similar to bone marrow transplantation. Doctors remove healthy immature cells (stem cells) from a patient's blood and store them before the patient receives high-dose chemotherapy and possibly radiation therapy to destroy the leukaemia cells. The stem cells are then returned to the patient, where they can produce new blood cells to replace cells destroyed by the treatment. (12 Dec 1998) |
| corneal transplantation | Partial or total replacement of the cornea from one human or animal to another. (12 Dec 1998) |
