| neurodermatosis | <dermatology, pathology> An extremely variable eczematous dermatosis presumed to be a cutaneous response to prolonged vigorous scratching, rubbing or pinching to relieve intense pruritus, having the potential to produce polymorphic lesions at the same or different times and varying in severity, course and morphologic expression in different individuals. It is believed by some authorities to be a psychogenic disorder. The term is also used to refer to lichen simplex chronicus (circumscribed neurodermatosis) and sometimes to atopic dermatitis (disseminated neurodermatosis). (04 Mar 1998) |

| neurodynamic | Pertaining to nervous energy. Origin: neuro-+ G. Dynamis, force (05 Mar 2000) |
| neurodynia | Synonym: neuralgia. Origin: neuro-+ G. Odyne, pain (05 Mar 2000) |
| neuroectoderm | <embryology> Ectoderm on the dorsal surface of the early vertebrate embryo that gives rise to the cells (neurons and glia) of the nervous system. Synonym: neural plate. (04 Mar 1998) |
| neuroectodermal | Relating to the neuroectoderm. (05 Mar 2000) |
| neuroectodermal junction | The margin of the embryonic neural plate separating it from the embryonic ectoderm; cells from this region form the neural crest. Synonym: neurosomatic junction. (05 Mar 2000) |
| neuroectodermal tumour, melanotic | A benign, rapidly growing, deeply pigmented tumour of the jaw and occasionally of other sites, consisting of an infiltrating mass of cells arranged in an alveolar pattern, and occurring almost exclusively in infants. Its source of origin is in dispute, the various theories giving rise to its several names. (12 Dec 1998) |
| neuroectodermal tumour, peripheral | A heterogeneous group of malignant neoplasms arising in either supportive structures or neuronal tissue. They occur in adolescents and young adults. This tumour shares a number of characteristics with ewing's sarcoma: it is highly cellular and consists of a monotonous pattern of primitive-appearing round cells. The chest wall is the most common site but the trunk, abdomen, and pelvis are other primary sites. (12 Dec 1998) |
| neuroectodermal tumour, primitive | A malignant brain tumour sharing common features and biologic properties with medulloblastoma. Some pathologists and clinicians use the terms interchangeably: they both can disseminate throughout the nervous system and, in some cases, systemically. most lesions arise from the posterior fossa in children under five years of age. The tumour often produces hydrocephalus and symptoms of increased intracranial pressure. Papilledema is often present. (12 Dec 1998) |
| neuroectodermal tumours | Malignant neoplasms arising in the neuroectoderm, the portion of the ectoderm of the early embryo that gives rise to the central and peripheral nervous systems, including some glial cells. (12 Dec 1998) |
| neuroectomy | Excision of a segment of a nerve. Synonym: neuroectomy. Origin: neur-+ G. Ektome, excision (05 Mar 2000) |
| neuroeffector junction | The synapse between a neuron (presynaptic) and an effector cell other than another neuron (postsynaptic). Neuroeffector junctions include synapses onto muscles and onto secretory cells. (12 Dec 1998) |
| neuroencephalomyelopathy | Disease of the brain, spinal cord, and nerves. (05 Mar 2000) |
| neuroendocrine | 1. Pertaining to the anatomical and functional relationships between the nervous system and the endocrine apparatus. 2. Descriptive of cells that release a hormone into the circulating blood in response to a neural stimulus. Such cells may comprise a peripheral endocrine gland (e.g., the insulin-secreting beta cells of the islets of Langerhans in the pancreas and the adrenaline-secreting chromaffin cells of the adrenal medulla); others are neurons in the brain (e.g., the neurons of the supraoptic nucleus that release antidiuretic hormone from their axon terminals in the posterior lobe of the hypophysis). (05 Mar 2000) |
| neuroendocrine cell | <endocrinology> A hormone secreted by specialised neurons (neuroendocrine cells), for example releasing hormones. (18 Nov 1997) |
