Exercise 1
Cardiac contractile cells are present in the atria and ventricles of heart and are responsible for the heart
contraction which pump the blood to the various body parts. In cardiac contractile cells the sarcomeres are
present which contain myofibril proteins along with the actin and myosin filaments. They also have
intercalated discs which allows the intercellular passage of ions and help in the transmission of the electrical
impulses rapidly. These all unique features are necessary for the heart contraction and are absent in the
skeletal and smooth muscle cells.
