Atrioventricular Trunk (Noun)
Meaning
A bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract.
Classification
Nouns denoting body parts.
Examples
- The atrioventricular trunk is a critical component of the heart's electrical conduction system, ensuring that the ventricles contract in a coordinated manner.
- In the fetal heart, the atrioventricular trunk is a single vessel that eventually splits into the left and right bundle branches.
- Damage to the atrioventricular trunk can lead to abnormal heart rhythms and potentially life-threatening arrhythmias.
- The atrioventricular trunk is composed of specialized cardiac muscle cells that are capable of transmitting electrical impulses rapidly.
- During embryonic development, the atrioventricular trunk forms from the fusion of the atrial and ventricular septa.
