- 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...
-
extra deflection that
reflects the
rapid depolarisation of the left ventricle,
followed by the
slower depolarisation of the
right ventricle. An incomplete...
-
prominent features on the ECG: the P wave (atrial
depolarisation), the QRS
complex (ventricular
depolarisation) and the T wave (ventricular repolarisation)...

Microinjection of
glutamic acid into
neurons produces spontaneous depolarisations around one
second apart, and this
firing pattern is
similar to what...
- an
influx of
positive ions
through the
channel to
cause nerve cell
depolarisation.
Phencyclidine inhibits the NMDA
receptor by
binding to the specific...
- 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...

ventricular repolarization or

abnormalities in
ventricular depolarisation.
Inverted T wave is

receptor action causing muscle relaxation,
instead of
continual depolarisation which is the
mechanism of
action of the
depolarizing neuromuscular junction...

conformational changes in the L-type
calcium channels following membrane depolarisation,
thereby resulting in a
drastic increase in
intracellular calcium levels...
