    Comparing the Cardiac muscle and the Skeletal muscle Differences Similarities Skeletal muscle is usually linked to bones by structures called tendons. Cardiac muscle is found in the heart. They are both important parts to the body. Skeletal muscle cells are usually arranged into cylindrical fibres with multiple nuclei and can be directly controlled by voluntary nerve signals from the nervous system. Cardiac muscle cells are normally shorter and are linked via gap junctions which allow compounds

    Wall The heart is composed of cardiac muscle which enable the heart to contract and allow the synchronization of the heart beat. The heart wall is divided into three layers: the epicardium‚ myocardium‚ and endocardium. * Epicardium - outer protective layer of the heart. * Myocardium - muscular middle layer wall of the heart. * Endocardium - inner layer of the heart that is continuous with the inner lining of blood  * Cardiac Conduction * Cardiac conduction is the rate at which

    Cardiac This is an involuntary muscle‚ found solely in the walls of the heart‚ as well as in the walls of the blood vessels. This sort of muscle has similarities with the skeletal muscles‚ because it is striated. Furthermore‚ it has slight similarities to the smooth muscles‚ because its contractions are not under conscious control. On the other hand this type of muscle is highly specialised. It is under the control of the autonomic nervous system‚ however‚ even without nervous imput contractions

    Compare and contrast cardiac and smooth muscle. In cardiac muscle‚ each heartbeat is triggered by the hearts own pacemaker cells‚ which initiate electrical discharge and when this reaches the contractile muscle cells (the cardiomyocytes)‚ they create an action potential which increases the concentration of calcium ions into the cell. Calcium ions play a key role in activating what is known as the contractile machinery – the actin and myosin filaments. The cardiac action potential‚ unlike other forms
