Bachmann's bundle
Bachmann's bundle
Bachmann's bundle (pronunciation: /ˈbɑːkmən/), also known as the interatrial band, is a part of the cardiac conduction system that plays a crucial role in the electrical activity of the heart.
Etymology
The term "Bachmann's bundle" is named after the German anatomist and histologist, Jean George Bachmann, who first described this structure in 1916.
Definition
Bachmann's bundle is a large, broad band of myocardial fibers. It originates from the sinoatrial node (SA node) and extends across the roof of the right atrium to the left atrium, facilitating the conduction of electrical impulses between the two atria.
Function
The primary function of Bachmann's bundle is to transmit electrical impulses from the SA node in the right atrium to the left atrium. This allows for the simultaneous contraction of both atria, ensuring efficient blood flow into the ventricles.
