| cardiac gating | Using an electronic signal from the cardiac cycle to trigger an event, such as in imaging separate phases of cardiac contraction. (05 Mar 2000) |

| gating | 1. In a biological membrane, the opening and closing of a channel, believed to be associated with changes in integral membrane proteins. 2. A process in which electrical signals are selected by a gate, which passes such signals only when the gate pulse is present to act as a control signal, or passes only the signals that have certain characteristics. See: gate. (05 Mar 2000) |
| gating current | <physiology> Small currents in the membrane just prior to the increase in ionic permeability, due to the movement of charged particles within the membrane. So called because they open the gates for current flow through ion channels. (20 Mar 1998) |
| gating mechanism | Occurrence of the maximum refractory period among cardiac conducting cells approximately 2 mm proximal to the terminal Purkinje fibres in the ventricular muscle, beyond which the refractory period is shortened through a sequence of Purkinje cells, transitional cells, and muscular cells; gating mechanism may be a cause of ventricular aberration, bidirectional tachycardia, and concealed extrasystoles, a mechanism by which painful impulses may be blocked from entering the spinal cord. Compare: gate-control theory. (05 Mar 2000) |
| channel gating | <physiology> Small currents in the membrane just prior to the increase in ionic permeability, due to the movement of charged particles within the membrane. So called because they open the gates for current flow through ion channels. (20 Mar 1998) |
| ion channel gating | The opening and closing of ion channels due to a stimulus. The stimulus can be a change in membrane potential (voltage-gated), drugs or chemical transmitters (ligand-gated), or a mechanical deformation. Gating is thought to involve conformational changes of the ion channel which alters selective permeability. (12 Dec 1998) |
| calcification, physiologic | Process by which organic tissue becomes hardened by the physiologic deposit of calcium salts. (12 Dec 1998) |
| physiologic | Normal, not pathologic, characteristic of or conforming to the normal functioning or state of the body or a tissue or organ, physiological. (18 Nov 1997) |
| physiologic age | Age estimated in terms of function. (05 Mar 2000) |
| physiologic albuminuria | Presence of slight traces of protein in otherwise normal urine. Synonym: functional albuminuria. (05 Mar 2000) |
| physiologic amenorrhoea | Amenorrhoea of pregnancy or the menopause, not associated with an organic disorder. (05 Mar 2000) |
| physiologic anaemia | An obsolete term for apparent anaemia caused by increased fluid volume of the blood (overhydration). (05 Mar 2000) |
| physiologic anisocoria | A common (20% of normals) benign inequality of the pupils that may change from one hour to the next. Synonym: essential anisocoria, physiologic anisocoria, simple-central anisocoria. (05 Mar 2000) |
| physiologic antidote | An agent that produces systemic effects contrary to those of a given poison. (05 Mar 2000) |
| physiologic congestion | Hyperaemia occurring during functional activity of an organ. Synonym: physiologic congestion. (05 Mar 2000) |
