As the axon repolarizes Na+ channels open to bring the cell from a resting state -70mv to -55mv and grater (grater being -55mv through 0mv).

Almost as soon as the depolarization wave begins a repolarization wave follows it across the membrane this occurs as?
This occurs as K+ diffuses out of the cell.
During an action potential repolarization occurs as a result of?
potassium ions diffusion to the outside of the cell membrain,
Atrial repolarization coincides in time with?
Atrial repolarization coincides with the QRS complex on the ECG. The T-wave corresponds to Ventricular repolarization. 'with tHE t-wave' <-- WRONG
Why is the ECG event indicating atrial repolarization not seen in an ECG?
It is on page 374 of your lab book assuming this is the same question that came out Lab 28 in the Ninth Edition of Seeley's Anatomy & Physiology. The atrial repolarization occurs during ventricualr depolarization and is masked by the larger QRS complex. I actually did my homework :)
How is the resting potential different from repolarization?
Repolarization is when the cell or neuron returns to be more negative. Depolarization is when the cell or neuron becomes less and less negative.
What is atrial repolarization indicated by?
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
Almost as soon as the depolarization wave begins a repolarization wave follows it across the membrane this occurs as?

Describe the action of depolarization and repolarization?
Depolarization is due to the influx of Na+ which causes the cell's internal membrane to become more positive, leading to an action potential. Repolarization occurs when K+ leaves the cell causing the interior of the cell to become negative again.
Repolarization of a ventricular cardiocyte taks longer then repolarization of a typical neuron?
yes
What is the portion of the ECG that indicates ventricular repolarization?
The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
Atrial repolarization coincides in time with?
Atrial repolarization coincides with the QRS complex on the ECG. The T-wave corresponds to Ventricular repolarization. 'with tHE t-wave' <-- WRONG

What does precordial repolarization disturbance mean?
Precordial repolarization disturbance is a heart condition that can be determined though an EKG. Precordial has to do with the area above your heart and repolarization has to do with the heart muscle preparing itself for it's next beat.
What does the t wave represent on an ecg?
It represents the repolorization of the ventricles. The ventricles must reset electrically after contracting. In a normal Sinus Rhythm the p wave comes first. Then the QRS complex which is the largest part of the heartbeat will come less than .2 seconds later. The QRS complex usually lasts less than .12 seconds. The final bump is (usually) the T wave.
What does ventricular repolarization result in?
contraction
What channels are open during depolarization and during repolarization?
During depolarization Na channels are open During repolarization K channels are open
