| normal occlusion | That arrangement of teeth and their supporting structure which is usually found in health and which approaches an ideal or standard arrangement. Synonym: normal bite. Synonym: neutral occlusion. (05 Mar 2000) |

| normal opsonin | That normally present in the blood, i.e., without stimulation by a known, specific antigen such as certain complement components; it is relatively thermolabile and reacts with various organisms. Synonym: common opsonin, thermolabile opsonin. Specific opsonin, antibodies formed in response to stimulation by a specific antigen, either as a result of an attack of a disease, or injections with a suitably prepared suspension of the specific microorganism. Synonym: immune opsonin, thermostable opsonin. (05 Mar 2000) |
| normal pressure hydrocephalus | <neurology> A brain disorder caused by blockage of the flow of cerebrospinal fluid (CSF), with enlargement of the ventricles of the brain (keep the pressure normal) and compression of brain tissue. Brain atrophy is the result. In this condition the CSF is produced normally but not reabsorbed. Symptom onset is gradual. A key feature is dementia. Treatment is surgical (VP shunt). (13 Nov 1997) |
| normal range | Normal results can fall outside the normal range. By convention, the normal range is set to cover ninety-five percent (95%) of values from a normal population. Five percent (5%) of normal results therefore fall outside the normal range. (12 Dec 1998) |
| normal serum | A nonimmune serum, usually with reference to a serum obtained prior to immunization. (05 Mar 2000) |
| normal tartrate | Tartrate that contains no uncombined acid groups. (05 Mar 2000) |
| normal toxin | A toxin solution holding exactly 100 lethal doses in 1 ml. (05 Mar 2000) |
| normal values | A set of laboratory test value's used to characterise apparently healthy individuals; now replaced by reference value's. (05 Mar 2000) |
| absolute refractory period | The period following excitation when no response is possible regardless of the intensity of the stimulus. (05 Mar 2000) |
| alabama period | <geology> A period in the American eocene, the lowest in the tertiary age except the lignitic. Source: Websters Dictionary (01 Mar 1998) |
| anaesthesia recovery period | The period of emergence from general anaesthesia, where different elements of consciousness return at different rates. (12 Dec 1998) |
| Gap1 period | The period of the cell cycle after cell division when there is synthesis of RNA and protein; it may last for a few hours in rapidly growing tissue or a lifetime in non-renewing cells such as nerve cells. Synonym: Gap1 phase, postmitotic phase. (05 Mar 2000) |
| Gap2 period | The period in the cell cycle when synthesis of DNA is completed but before mitosis begins. Synonym: Gap2 phase, premitotic phase. (05 Mar 2000) |
| masticatory silent period | A pause in electromyographic patterns associated with tooth contacts during chewing and biting; a part of the complex feedback mechanism of mandibular control involving receptors in the periodontal ligament and muscles. (05 Mar 2000) |
| refractory period | <neurology, physiology> most commonly used in reference to the interval (typically 1ms) after the passage of an action potential during which an axon is incapable of responding to another. This is caused by inactivation of the sodium channels after opening. The maximum frequency at which neurons can fire is thus limited to a few hundred Hertz. An analogous refractory period occurs in individuals of Dictyostelium discoideum, which are insensitive to extracellular cyclic AMP immediately after a pulse of cAMP has been secreted. The term can be applied to any system where a similar insensitive period follows stimulation. (18 Nov 1997) |
