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

2 Positive and negative effects of a particular scientific advance Cardiac MRI (Heart MRI) What Is a Heart MRI? A magnetic resonance imaging test (MRI) uses magnets and radio waves to capture images inside your body without making an surgical incision. An MRI allows your doctor to see the soft tissues in your body‚ along with your bones. An MRI can be performed on any part of your body. However‚ a heart or cardiac MRI looks specifically at your heart and the adjacent vessels. Unlike a CT

It would be prudent to understand how the heart functions in the first place before going in depth into the various problems that might arise within the cardiac cycle. Of which a large number are covered under the various Arrhythmias‚ which can be divided into two major groups‚ ventricular arrythythmias and supraventricular arrythythmias. I.e.‚ arrythythmias that occur in the ventricles and arrythythmias

Sudden cardiac arrest is the largest cause of nature death in the United States‚ causing about 325‚000 deaths in the United States annually. Half of all heart disease deaths are caused by sudden cardiac arrest. (Cleveland Clinic) Sudden cardiac arrest is the sudden‚ unexpected loss of heart function‚ which is caused by abnormality in heart rhythm which is a result from problem with heart’s electrical. Sudden cardiac arrest is more frequent in adults in their mid 30’s and 40’s and is more likely

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

disease is the number one killer in the United States of America. Sudden cardiac death‚ or SCD‚ is the largest cause of natural death in the United Sates. SCD causes about three hundred twenty-five thousand adult deaths each year in the US. Half of all heart disease deaths are caused by sudden cardiac arrest. Occurring mainly in adults in their mid-thirties to mid-forties‚ SCD affects only one or two children each year. Sudden cardiac arrest is not a heart attack‚ or myocardial infarction‚ but it is possible

CONGESTIVE CARDIAC FAILURE Congestive cardiac failure is defined as “the state in which the heart is unable to pump blood at a rate adequate for supplying the requirements of the tissues with function parameters remaining within normal limits usually accompanied by effort intolerance‚ fluid retention and reduced longevity” (Denolin‚ 1983‚ p. 445). Congestive cardiac failure or heart failure continues to be a major public health issue worldwide. This paper is a case study report about C.B‚ a 60

The cardiac conduction system of the heart consists of specialized muscle cells that generate and send rhythmic electrical impulses to the myocardium in order for the heart to contract (Cardiac Conduction System‚ 2016). When there is the normal rhythm of the heart it is called sinus rhythm and any deviation from sinus rhythm is called an arrhythmia (Saladin‚ 2012). Electrocardiograms (ECG) record the electrical impulses and help determine when there are any abnormalities in the way the heart functions
