inner layer of the heart wall consisting of epithelium and connective tissue as well as some specialized muscle tissue
fibers attatched to the tricuspid valve which pull it closed when papillary muscles contract, preventing backwash of blood
responsible for pulling the atrioventricular valves closed by means of the chordae tendineae
atrial systole/ventricular diastole, ventricular systole/atrial diastole, brief complete diastole
cardiac conduction system
fibers of cardiac muscle tissue which distribute impulses over the entire heart
small, elongated mass of specialized cardiac muscle tissue just beneath the epicardium in the right atrium near the opening of the superior vena cava-starts impulses
group of fibers which receive impluse from the atrioventricular node; also known as the bundle of His
extend from branches of A-V bundle, stimulate muscle fibers in the ventricular walls
recording of the electrical changes that occur in the myocardium during a cardiac cycle
prominent muscular ridges along the inner surface of the auricle and across the adjacent anterior atrial wall
