The following: Similarity between the contraction of myocardium and a skeletal muscle twitch. The inability of myocardium to exhibit summation and tetanus. Introduction: Cardiac cells or myocardial cells are present only in the heart. They are striated like skeletal muscles and have actin-myosin filaments. They are small in length and are present in branched and connected form. The alternate myocardial cells are joined together by gap junctions or electrical synapse.
