Cardiac Conduction

Question 1

Electrical pathway through the heart

Answer 1

Sinoatrial node, Atrial myocardium, Atrioventricular Node, Bundle of His, Right/Left bundle branches, Purkinje Fibers, Ventricular Myocardium

Question 2

Sinoatrial node function

Answer 2

Initiates and regulates heart beat. Sends electrical signals to both atria, telling them to contract

Question 3

Atrioventricular Node Function

Answer 3

Delays passage of electrical impulses to the ventricles to ensure all blood is pumped out of atria.

Question 4

Bundle of His Function

Answer 4

transmits signals to the branches

Question 5

Right/Left Bundle Branch Function

Answer 5

Right branch innervates right ventricle, left branch innervates left ventricle

Question 6

Purkinje fibers

Answer 6

send signals to the myocardial cells
