| face-bow fork | <dentistry> That part of the face-bow assemblage used to attach the maxillary trial base to the face-bow proper. Synonym: bite fork. (05 Mar 2000) |
|---|---|
| face-bow record | <dentistry> A registration utilizing a face-bow of the position of the hinge axis and/or the condyles; the face-bow record is used to orient the maxillary cast to the opening and closing axis of the articulator. (05 Mar 2000) |
| face form | The outline form of the face, the outline form of the face from an anterior view. (05 Mar 2000) |
| face peel | <procedure> Removal of skin blemishes such as wrinkles, freckles, or acne scars by chemical agents producing injury (trichloracetic, phenol, or other organic acids) or solid carbon dioxide. (05 Mar 2000) |
| face validity | The extent to which the items of a test or procedure appear superficially to sample that which is to be measured. (05 Mar 2000) |
| kinematic face-bow | adjustable axis face-bow |
| foetal face syndrome | <syndrome> A syndrome of facies resembling an early foetus with short forearms, and genital hypoplasia at birth, but without evidence of achondroplasia; leads to dwarfism without mental retardation. Synonym: Robinow's syndrome. (05 Mar 2000) |
| forming face | The side of the Golgi apparatus which faces the rough endoplasmic reticulum, where vesicles budding off of the rough endoplasmic reticulum fuse to the Golgi apparatus. Also called the cis side of the Golgi apparatus. (09 Oct 1997) |
| frog face | The appearance caused by broadening of the nose which occurs in certain cases of nasal polyps. (05 Mar 2000) |
| adhesion phenomenon | A phenomenon manifested by the adherence of antigen-antibody-complement complex to "indicator cells" (microorganisms, platelets, leukocytes, or erythrocytes), the reaction being sensitive and specific for the antigen and antibody in the complex. Synonym: erythrocyte adherence phenomenon, immune adherence phenomenon, red cell adherence phenomenon. (05 Mar 2000) |
| AFORMED phenomenon | As induced pulsus alternans progresses, a state in which alternating heart depolarisations fail to eject any blood, thus allowing longer diastolic filling; the subsequent beat is then able to produce a significant ejection; at high rates the cardiac minute volume and blood pressure may appear normal. Origin: Alternating, failure of response, mechanical, to electrical depolarisation (05 Mar 2000) |
| all-or-nothing phenomenon | <physiology> Refers to the phenomenon where the strength of a nerve impulse is not dependent on the strength of the stimulus. Instead, there is a threshold level of stimulus strength that must be reached before the nerve will fire an impulse (at full capacity). Below the threshold, the nerve will not fire at all. <cardiology> It also refers to the same phenomenon observed in the heart muscle, which will either contract fully or not at all. <psychology> In studies of behaviour, it refers to the same phenomenon where a behavioural stimulus will either produce a complete response or no response at all. Also called all-or-nothing principle, all-or-none law, all-or-none responsiveness, etc. (15 Nov 1997) |
| Anrep phenomenon | Homeometric autoregulation of the heart whereby cardiac performance improves as the afterload (aortic pressure) is increased. (05 Mar 2000) |
| aqueous influx phenomenon | The filling of the aqueous vein, which normally carries blood and aqueous, with aqueous, when the junction of the aqueous vein and the recipient vein is partially occluded. Synonym: Ascher's aqueous influx phenomenon. (05 Mar 2000) |
| Arias-Stella phenomenon | Focal, unusual, decidual changes in endometrial epithelium, consisting of intraluminal budding, and nuclear enlargement and hyperchromatism with cytoplasmic swelling and vacuolation; may be associated with ectopic or uterine pregnancy. Synonym: Arias-Stella effect, Arias-Stella reaction. (05 Mar 2000) |
