| neurosarcoidosis | Sarcoidosis is a granulomatous disease of unknown aetiology. Involvement the central nervous system is referred to as neurosarcoidosis. This condition generally occurs only if there has been substantial systemic involvement. (27 Sep 1997) |
|---|---|
| neurosarcoma | <tumour> A sarcoma with neuromatous elements; includes neurofibrosarcoma, neurogenic sarcoma, and malignant schwannoma. (05 Mar 2000) |
| neuroschwannoma | <tumour> A benign, encapsulated neoplasm in which the fundamental component is structurally identical to a syncytium of Schwann cells; the neoplastic cells proliferate within the endoneurium, and the perineurium forms the capsule. The neoplasm may originate from a peripheral or sympathetic nerve, or from various cranial nerves, particularly the eighth nerve; when the nerve is small, it is usually found (if at all) in the capsule of the neoplasm; if the nerve is large, the neurilemoma may develop within the sheath of the nerve, the fibres of which may then spread over the surface of the capsule as the neoplasm enlarges. Microscopically, neurilemoma's are composed of combinations of two cell types, Antoni types A and B (see below), either of which may be predominant in various examples of neurilemoma's. See: neurofibroma. Synonym: neurilemoma, neuroschwannoma. Origin: Theodor Schwann + -oma (05 Mar 2000) |
| neurosciences | The scientific disciplines concerned with the embryology, anatomy, physiology, biochemistry, pharmacology, etc., of the nervous sytem. (12 Dec 1998) |
| neurosecretion | The release of a secretory substance from the axon terminals of certain nerve cells in the brain into the circulating blood. The secretory product may be a true hormone, e.g., the antidiuretic hormone released from the axon terminals of the neurons composing the supraoptic nucleus of the hypothalamus; in the case of the so-called releasing-factor neurons of the hypothalamus the cell product is not a systemic hormone in its own right but elicits the release of trophic hormones by the anterior lobe of the hypophysis, substances that in turn stimulate peripheral endocrine glands to release their systemically active hormones. (05 Mar 2000) |
| neurosecretory | Relating to neurosecretion. (05 Mar 2000) |
| neurosecretory cell | Cells that have properties both of electrical activity, carrying impulses and a secretory function, releasing hormones into the bloodstream. In a sense, they are behaving in the same way as any chemically signalling neuron, except that the target is the blood (and remote tissues), not another nerve or post synaptic region. (18 Nov 1997) |
| neurosecretory cells | Nerve cell's, such as those of the hypothalamus, that elaborate a chemical substance (such as a releasing factor, neuropeptide, or, more rarely, a true hormone) that influences the activity of another structure (e.g., anterior lobe of the hypophysis). See also neurosecretion. (05 Mar 2000) |
| neurosecretory substance | The secretion of nerve cell bodies located in the hypothalamus; the substance is transported by way of hypothalamo-hypophysial tract fibres into the neurohypophysis where the terminals of the nerve fibres contain the secretion. As seen in the fibres and terminals with a light microscope, the substance appears as Herring bodies or hyaline bodies of the pituitary (see under body). See: hyaline bodies of pituitary. (05 Mar 2000) |
| neurosecretory systems | A system of neurons that has the specialised function to produce and secrete hormones, and that constitutes, in whole or in part, an endocrine organ or system. (12 Dec 1998) |
| neurosensiferous | <zoology> Pertaining to, or forming, both nerves and sense organs. Origin: neuro- + sensiferous. Source: Websters Dictionary (01 Mar 1998) |
| neurosis | Origin: NL, fr. Gr. Nerve. <medicine> A functional nervous affection or disease, that is, a disease of the nerves without any appreciable change of nerve structure. Source: Websters Dictionary (01 Mar 1998) |
| neurosis tarda | Neurotic patterns developing in older people, related to organic cerebral lesions. (05 Mar 2000) |
| neuroskeletal | Of or pertaining to the neuroskeleton. Source: Websters Dictionary (01 Mar 1998) |
| neuroskeleton | <anatomy> The deep-seated parts of the vertebrate skeleton which are relation with the nervous axis and locomation. Origin: Neuro- + skeleton. Source: Websters Dictionary (01 Mar 1998) |
