| fish-mouth meatus | A red and swollen condition of the orifice of the urethra (urinary meatus) in gonorrhoea. Internal acoustic meatus, a canal running from the opening of the internal acoustic meatus, through the petrous portion of the temporal bone, ending at the fundus where a thin plate of bone separates it from the vestibule; it gives passage to the facial and vestibulocochlear nerves together with the labyrinthine artery and veins. Synonym: meatus acusticus internus, internal auditory meatus. (05 Mar 2000) |

| fish-mouth mitral stenosis | Extreme mitral stenosis. (05 Mar 2000) |
| foot-and-mouth disease | <disease> A highly infectious disease of wide distribution and great economic importance, occurring in cattle, swine, sheep, goats and all wild and domestic cloven-footed animals caused by a picornavirus (genus Rhinovirus) and characterised by vesicular eruptions in the mouth, tongue, hoofs, and udder; humans are rarely affected. Synonym: aftosa. (05 Mar 2000) |
| foot-and-mouth disease virus | A picornavirus of the genus Rhinovirus causing foot-and-mouth disease of cattle, swine, sheep, goats, and wild ruminants; it has wide distribution throughout Africa and Asia, causing serious economic losses; the virus is spread by contamination of the animal environment with infected saliva and excreta. Synonym: FMD virus. (05 Mar 2000) |
| foot-and-mouth disease virus vaccines | Vaccine's either of inactivated virus from infected cattle tongue epithelium or, more recently, of live virus attenuated by embryonated egg or mouse passage and propagated in tissue culture. (05 Mar 2000) |
| lips of mouth | Lips of the mouth. Synonym: labia oris. (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) |
| arm phenomenon | In tetany, spasm both of the extensor muscles of the knee and of the calf muscles when the extended leg is flexed at the hip. Synonym: leg phenomenon, Pool-Schlesinger sign, Schlesinger's sign. In tetany, contraction of the arm muscles following the stretching of the brachial plexus by elevation of the arm above the head with the forearm extended, resembles the contraction resulting from stimulation of the ulnar nerve. Synonym: arm phenomenon. (05 Mar 2000) |
| Arthus phenomenon | A form of immediate hypersensitivity resulting in erythema, oedema, haemorrhage, and necrosis observed in rabbits after injection of antigen to which the animal has already been sensitised and has specific IgG antibodies. The reaction is caused by the inflammation that results from the deposition of antigen-antibody complexes in tissue spaces and in blood vessel walls that activate complement, most of the damage seemingly being due to the polymorphonuclear leukocytes that phagocytise the deposits and release lysosomal enzymes. The phenomenon, described by Arthus, was in rabbits, but similar reactions (Arthus-type reactions) are observed in guinea pigs, rats, and dogs, as well as in humans. See: Arthus reaction. Synonym: Arthus reaction. (05 Mar 2000) |
| Ascher's 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) |
