单词 atrioventricular node
例句 atrioventricular node
Electrical charges pulse from the SA node causing the two atria to contract in unison; then the pulse reaches the atrioventricular node between the right atrium and right ventricle. Biology for AP Courses 2022-06-09T00:00:00Z
This impulse spreads from its initiation in the SA node throughout the atria through specialized internodal pathways, to the atrial myocardial contractile cells and the atrioventricular node. Anatomy and Physiology 2013-06-19T00:00:00Z
The ventricles would contract, but the atria would not, because the atrioventricular node passes the signal to the Purkinje fibers, which allow the ventricles to contract. Biology for AP Courses 2022-06-09T00:00:00Z
The atria would contract, but the ventricles would not, because the atrioventricular node passes the signal to the Purkinje fibers, which allow the atria to contract. Biology for AP Courses 2022-06-09T00:00:00Z
The ventricles would contract, but the atria would not, because the atrioventricular node passes the signal to the Purkinje fibers, which causes the atria to contract. Biology for AP Courses 2022-06-09T00:00:00Z
Explain fully how the cardiac cycle would be affected if the signal was blocked at the atrioventricular node and why. Biology for AP Courses 2022-06-09T00:00:00Z
The relative importance of this pathway has been debated since the impulse would reach the atrioventricular node simply following the cell-by-cell pathway through the contractile cells of the myocardium in the atria. Anatomy and Physiology 2013-06-19T00:00:00Z
It is the excitation of cardiac muscle cells at the atrioventricular node followed by the sinoatrial node. Biology for AP Courses 2022-06-09T00:00:00Z
Figure 19.19 illustrates the initiation of the impulse in the SA node that then spreads the impulse throughout the atria to the atrioventricular node. Anatomy and Physiology 2013-06-19T00:00:00Z
How does the delay of the impulse at the atrioventricular node contribute to cardiac function? Anatomy and Physiology 2013-06-19T00:00:00Z
The atria would contract, but the ventricles would not, because the atrioventricular node passes signals to the Purkinje fibers, which allow the ventricles to contract. Biology for AP Courses 2022-06-09T00:00:00Z
Regardless of the pathway, as the impulse reaches the atrioventricular septum, the connective tissue of the cardiac skeleton prevents the impulse from spreading into the myocardial cells in the ventricles except at the atrioventricular node. Anatomy and Physiology 2013-06-19T00:00:00Z
