| neurocranial granulomatous arteritis | A small vessel giant cell arteritis which affects only intracranial blood vessels, of unknown aetiology, and with diverse clinical manifestations, including those seen with an involving cerebral tumour, and with a lower grade meningitis, leading to infarction of one portion of the cerebrum or cerebellum.

| neurocranium | Those bones of the skull enclosing the brain, as distinguished from the bones of the face. Synonym: braincase, cranial vault, cranium cerebrale, cerebral cranium. Origin: neuro-+ G. Kranion, skull (05 Mar 2000) |
| neurocristopathy | Developmental anomaly of the neural crest manifested by abnormal development and tumours of the neural axis. Origin: neuro-+ L. Crista, crest, + G. Pathos, suffering (05 Mar 2000) |
| neurocutaneous melanosis | Cutaneous giant pigmented nevi associated with melanosis of the leptomeninges; malignant melanomas may develop in the skin or meninges. (05 Mar 2000) |
| neurocutaneous syndrome | <syndrome> The occurrence of nevi and sometimes various skeletal deformities with symptoms pointing to gliosis or abiotrophy of the central nervous system. (05 Mar 2000) |
| neurocyte | Synonym: neuron. Origin: neuro-+ G. Kytos, cell (05 Mar 2000) |
| neurocytolysis | Destruction of neurons. Origin: neuro-+ G. Kytos, cell, + lysis, dissolution (05 Mar 2000) |
| neurocytoma | A benign brain tumour consisting of undifferentiated cells of nervous origin, i.e., cells resembling medullary neural epithelium. (12 Dec 1998) |
| neurodegenerative diseases | A varied assortment of central nervous system disorders characterised by gradual and progressive loss of neural tissue. (cecil textbook of medicine, 20th ed, p2050) (12 Dec 1998) |
| neurodegenerative disorder | A type of neurological disease marked by the loss of nerve cells. See: Alzheimer's disease, Parkinson's disease. (22 May 1997) |
| neurodendrite | A long, branching outgrowth or extension from a neuron, that carries electrical signals from synapses to the cell body, unlike an axon that carries electrical signals away from the cell body. Each nerve cell usually has many dendrites. This classical definition, however, lost some weight with the discovery of axo-axonal and dendro-dendritic synapses. (29 Sep 1997) |
| neurodendron | A long, branching outgrowth or extension from a neuron, that carries electrical signals from synapses to the cell body, unlike an axon that carries electrical signals away from the cell body. Each nerve cell usually has many dendrites. This classical definition, however, lost some weight with the discovery of axo-axonal and dendro-dendritic synapses. (29 Sep 1997) |
| neurodermatitis | <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) |
