| tumour escape | The ability of tumours to evade destruction by the immune system. Theories concerning possible mechanisms by which this takes place involve both cellular and humoral immunity, and also costimulatory pathways related to CD28 antigens and CD80 antigens. (12 Dec 1998) |
|---|---|
| A-V junctional rhythm | The cardiac rhythm when the heart is controlled by the A-V junction (including node); arising in the A-V junction, the impulse ascends to the atria and descends to the ventricles, each at varying speeds depending on site of the pacemaker. Synonym: A-V junctional rhythm, nodal bradycardia, nodal rhythm. (05 Mar 2000) |
| A-V junctional tachycardia | Tachycardia originating in the A-V junction. Synonym: A-V junctional tachycardia, nodal tachycardia. (05 Mar 2000) |
| tachycardia, ectopic junctional | A tachycardia arising in the conduction tissues surrounding the atrioventricular node. It usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication. The rate may range from 140 to 250 beats per minute. (12 Dec 1998) |
| epidermolysis bullosa, junctional | Form of epidermolysis bullosa having onset at birth or during the neonatal period and transmitted through autosomal recessive inheritance. It is characterised by generalised blister formation, extensive denudation, and separation and cleavage of the basal cell plasma membranes from the basement membrane. (12 Dec 1998) |
| junctional basal lamina | <cell biology> Specialised region of the extracellular matrix surrounding a muscle cell, at the neuromuscular junction. May be responsible for localisation of acetylcholine receptors in the synaptic region and also binds acetylcholine esterase to this region (18 Nov 1997) |
| junctional complex | The attachment zone between epithelial cells, typically consisting of the zonula occludens, the zonula adherens, and the macula adherens (desmosome). (05 Mar 2000) |
| junctional cyst | A cyst of the testis arising from the structures connecting the rete testis with the epididymis. (05 Mar 2000) |
| junctional epithelium | A collar of epthelial cells attached to the tooth surface and subepithelial connective tissue found at the base of the gingival crevice. Synonym: epithelial attachment. (05 Mar 2000) |
| junctional extrasystole | An extrasystole arising from the "junctional" tissues, either the A-V node or A-V bundle. Synonym: junctional extrasystole. (05 Mar 2000) |
| junctional rhythm | Rhythms originating anywhere within the A-V junction. Formerly, "A-V nodal" or simply "nodal" rhythms. (05 Mar 2000) |
| junctional tachycardia | Supraventricular tachycardia arising from the atrioventricular junction (formerly called nodal tachycardia). (05 Mar 2000) |
| ambiguous atrioventricular connections | Connections in which half the atrioventricular junction is connected concordantly and the other half is discordantly connected. (05 Mar 2000) |
| anomalous atrioventricular excitation | Ectopic atrial beat conducted to the ventricle. (05 Mar 2000) |
| anterior cusp of atrioventricular valve | The anterior leaflet or valvule of either the tricuspid or mitral valves. Synonym: cuspis anterior valvae atrioventricularis dextrae/sinistrae. (05 Mar 2000) |
