What is the function of the bundle of His?
The bundle of His is a part of the electrical system of the heart. It is a collection of cells that carry electrical signals from the AV node to the bundle branches. The electrical system that controls the heartbeat is made up of several parts that signal the heart muscle to contract.
What is the purpose of the bundle of His quizlet?
The bundle of His is an important part of the electrical conduction system of the heart, as it transmits impulses from the atrioventricular node, located at the inferior end of the interatrial septum, to the ventricles of the heart.
What septum is the bundle of His located in quizlet?
-A group of fibers located within the interventricular septum. -Fibers carry an electrical impulse to ensure the sequence of the heart contractions.
What is AV node quizlet?
Atrioventricular (AV) node. A region of specialized heart muscle tissue between the left and right atria where electrical impulses are delayed allowing both atria to contract completely before spreading to the AV bundle; receives impulses from atrial syncytium.
What is a bundle of His?
The bundle of His is an elongated segment connecting the AV Node and the left and right bundle branches of the septal crest. It is approximately 1.8 cm long in an adult heart[4] and is primarily located deep within the dense connective tissue.
Who discovered the bundle of His?
Wilhelm His Jr.
Wilhelm His Jr. (1863-1934) was a Swiss-born cardiologist and anatomist. In 1893, he discovered the bundle of His-the specialized tissue in the heart that transmits the electrical impulses and helps synchronize contraction.
What do Purkinje fibers do quizlet?
What is the function of the purkinje fibers? Send nerve impulses to the cells in the ventricles of the heart and cause them contract and pump blood either to the lungs or the rest of the body. Receives impulses from the AV node and extends into the interventricular septum before dividing into left and right bundles.
What is the role of the right and left bundle branches in the cardiac conduction system quizlet?
Terms in this set (54) Located at the interventricular septum, the Bundle of His divides into the right and left bundle branches, the function of which is to conduct the electrical impulse to the Purkinje fibers throughout the ventricles.
Where is the AV node located in the heart quizlet?
The AV node is an area of specialized tissue between the atria and the ventricles of the heart, specifically in the posterior inferior region of the inreratrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles.

Where is the AV node located within the heart quizlet?
-located on the floor of the right atrium near the interatrial septum. From here, it transmits the electrical impulses onward to the bundle of His. You just studied 2 terms!
What is the Bachmann’s bundle?
Bachmann’s bundle (BB), also known as the interatrial bundle, is well recognized as a muscular bundle comprising of parallel aligned myocardial strands connecting the right and left atrial walls and is considered to be the main pathway of interatrial conduction.
