| sprains and strains | A collective term for muscle and ligament injuries without dislocation or fracture. A sprain is a joint injury in which some of the fibres of a supporting ligament are ruptured but the continuity of the ligament remains intact. A strain is an overstretching or overexertion of some part of the musculature. (12 Dec 1998) |

| national institute for occupational safety and health | An institute of the centres for disease control and prevention which is responsible for assuring safe and healthful working conditions and for developing standards of safety and health. Research activities are carried out pertinent to these goals. (12 Dec 1998) |
| standards and guidelines | Bounds or constraints within which all practices in a given area will be carried out, in achieving the goals and objectives for that area. Standards and guidelines provide environmental safeguards and also describe constraints prescribed by law. (05 Dec 1998) |
| nebulisers and vaporisers | Devices that cause a liquid or solid to be converted into an aerosol (spray) or a vapor. It is used in drug administration by inhalation, humidification of ambient air, and in certain analytical instruments. (12 Dec 1998) |
| state health planning and development agencies | Agencies established under pl93-641 to coordinate, conduct, and implement state health planning activities. Two primary responsibilities are the preparation of an annual state health plan and giving assistance to the statewide health coordinating council. (12 Dec 1998) |
| neonatal diseases and abnormalities | Diseases existing at birth and often before birth, regardless of causation. Of these congenital diseases, those characterised by structural deformities are termed abnormalities. (12 Dec 1998) |
| neoplasms, adnexal and skin appendage | Neoplasms composed of sebaceous or sweat gland tissue or tissue of other skin appendages. The concept does not refer to neoplasms located in the sebaceous or sweat glands or in the other skin appendages. (12 Dec 1998) |
| neoplasms, complex and mixed | Neoplasms composed of more than one type of neoplastic tissue. (12 Dec 1998) |
| neoplasms, connective and soft tissue | Neoplasms developing from some structure of the connective and subcutaneous tissue. The concept does not refer to neoplasms located in connective or soft tissue. (12 Dec 1998) |
| neoplasms, cystic, mucinous, and serous | Neoplasms containing cyst-like formations or producing mucin or serum. (12 Dec 1998) |
| neoplasms, ductal, lobular, and medullary | Neoplasms, usually carcinoma, located within the centre of an organ or within small lobes, and in the case of the breast, intraductally. The emphasis of the name is on the location of the neoplastic tissue rather than on its histological type. most cancers of this type are located in the breast. (12 Dec 1998) |
| neoplasms, glandular and epithelial | Neoplasms composed of glandular tissue, an aggregation of epithelial cells that elaborate secretions, and of any type of epithelium itself. The concept does not refer to neoplasms located in the various glands or in epithelial tissue. (12 Dec 1998) |
| nephelometry and turbidimetry | Chemical analysis based on the phenomenon whereby light, passing through a medium with dispersed particles of a different refractive index from that of the medium, is attenuated in intensity by scattering. In turbidimetry, the intensity of light transmitted through the medium, the unscattered light, is measured. In nephelometry, the intensity of the scattered light is measured, usually, but not necessarily, at right angles to the incident light beam. (12 Dec 1998) |
| neuropathies, hereditary motor and sensory | A group of slowly progressive inherited disorders in which the predominant involvement is the peripheral motor neurons with lesser involvement of the peripheral sensory neurons. Neuronal degeneration and atrophy are characteristic of these disorders. Some of the associated characteristics are phytanic acid excess, optic atrophy, and retinitis pigmentosa. (12 Dec 1998) |
| neuropathies, hereditary sensory and autonomic | A group of inherited disorders in which there is selective involvement of the peripheral sensory and autonomic neurons and degeneration of fibres by axonal atrophy and degeneration. Five types of disorders have been described and classified type I through type v. (12 Dec 1998) |
