The nerve impulse causes the release of acetylcholine from the motor end plate. This causes the depolarization of the membrane of the adjacent muscle cell.

The ventricle contraction of the heart occurs iummediately after depolarization of the?
purkinje fibers
Does depolarization mean contraction?
yes
What part of an ECG represents ventricular depolarization?
Okay so an EKG show the electrical impulse that travels through the heart. What I mean is EKG don't show contraction. However the QRS complex represent ventricular depolarization, which signals ventricular contraction
What is the key intracellular event that stimulates muscle contraction?
Depolarization
Is depolarization in the heart passed cell to cell in the same way they are the neuromuscular junction?
false
What contraction of the atria results from which wave of depolarization on the ECG tracing?
P wave
Which simple mineral is crucial to your heart health?
Calcium is the biggest one. Sodium is another. Calcium is important because it plays a key role in the heart's contraction and ventricular depolarization processes. Without enough calcium, the heart will not contract properly.
The p wave corresponds to depolarization of the muscle fibers of the?
The p wave on a heart telemetry monitor represents the depolarization of the atria of the heart.
Which pump is responsible for muscle contraction through depolarization of muscle cell membrane?
Ca2+
What is the pumping action of the heart called?
atrial and ventricular systole occur at the same time
How do you treat heart depolarization?
umaima siddiq is good
What part of an ecg do atria contract?
Atrial depolarization occurs at the P wave. The atrial contraction occurs at the peak of the wave at the influx of calcium ions to prolong depolarization.
