We have more than 600 muscles in our bodies. They pump blood throughout your body‚ and help you lift heavy things like backpacks‚ and textbooks. You could control some of your muscles‚ while others like your heart‚ have their own jobs without us thinking at all. Muscles are all made up of same material. A type of tissue like the material in a rubber band. Thousands or tens of thousands of small fibers make up all or each muscle in our body. There are different muscles‚ fibers‚ and contractions.

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

regulatory protein (StAR). Within the mitochondria CHOL is converted to pregnenolone (PREG) by the side-chain cleavage enzyme known as CYP11A1. The conversion to PREG is the rate-limiting step and the following intermediate steps are taken place in the smooth endoplasmatic reticulum . PREG is either converted to 17α-hydroxypregnenolone (OH PREG) by the 17α-hydroxylase activity of CYP17A1 or converted to progesterone (PROG) by the enzyme 3β-hydroxysteroid dehydrogenase (3β-HSD). PROG is further converted

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

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
