Definition of Depolarisation. Meaning of Depolarisation. Synonyms of Depolarisation

- In biology, depolarization or hypopolarization is a change within a cell, during which the cell undergoes a shift in electric charge distribution, resulting...
- this begins at the sinoatrial node (SA node); from here the wave of depolarisation travels down to the apex of the heart. The hexaxial reference system...
- prominent features on the ECG: the P wave (atrial depolarisation), the QRS complex (ventricular depolarisation) and the T wave (ventricular repolarisation)...
- into the beta cells and degraded. The end effect of this is to cause depolarisation of the cell membrane which stimulates the release of the insulin. The...
- slowly rising current (ramp depolarisation) in vitro. The Hodgkin–Huxley model also shows accommodation. Sudden depolarisation of a nerve evokes propagated...
- A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. It is necessary, but not sufficient, for normal...
- maintain the existence of the resting membrane potential by countering the depolarisation due to the leakage of ions not at the electrochemical equilibrium (e...
- extra deflection that reflects the rapid depolarisation of the left ventricle, followed by the slower depolarisation of the right ventricle. An incomplete...
- an influx of positive ions through the channel to cause nerve cell depolarisation. Phencyclidine inhibits the NMDA receptor by binding to the specific...
- negative and therefore exists closer to the threshold potential. Cellular depolarisation can be due to a raised external concentration of pot****ium ions K+,...
