Cardiac muscle

(ECG) is used to identify any irregular heart rhythms. It does this by detecting the electrical activity of the heart as line tracings on paper, for easier analysis (Price, 2012). As Stanfield (2014) reports the cardiac muscle contracts in response to electrical depolarisation of the muscle cells. This electrical activity, when amplified and recorded, is known as an ECG. According to Maron et al, (2014) an ECG test can help detect the cause of symptoms such as chest pains or heart palpitations.…

imbalance, muscle loss, immunity and blood flow issues, and heart problems. Once the body reaches the point of malnutrition it goes into what is known as starvation mode. When a body lacks the nutrients it needs it will take from itself. When the human body has an electrolyte imbalance caused by starvation there can be a deficiency of potassium, calcium, and sodium. Sodium is used to balance fluid and control nerve and muscle function. Extremely low sodium and potassium levels can cause…

When someone dials 911, they expect someone to be there to help them. Whether they just had a slight fall, or are suffering from Cardiac Arrest, first responders need to be there for the citizens they serve. If a first responder is injured and cannot do their job properly, then they are putting the safety of the citizens at risk. The job of a first responder is to be there for the citizens, which is why workplace safety is always important to keep in mind. In the Fire and Emergency Services…

The musculoskeletal system provides form, support, stability and it is responsible for the movement of the body. The strong protective skeletal layer protects vital organs. For example rib cage protects the heart, kidneys and lungs from any traumatic injury. Bones provide framework that supports and keeps the body from collapsing. It is the major supporting structure of the body. The bone is classified by their shape or structure as cortical bones are dense and compact and cancellous is spongy.…

made different and ever-changing things but can function as a whole. In this paper I will explain how just one mineral can play a massive role in keeping your nerves, muscles and bones healthy. Magnesium is a cofactor in more than 300 enzyme systems that regulate varied biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation. It’s crucial for energy production, oxidative phosphorylation, and glycolysis. It…

Lofton Suzauna Adams Glossary Arrhythmia: occurs when the heart no longer beats in a pattern considered regular or normal. Cardiac arrest: the sudden loss of heart function, breathing and consciousness caused by abnormal or irregular heart rhythms (ex: ventricular fibrillation) Cardiomyopathy: a disease of the heart muscle (myocardium), may be acquired or hereditary Defibrillation: administration of a controlled electric shock to stop an extremely rapid, irregular…

direct or indirect skeletal muscle injury. The damage sustained results in the muscle fibres releasing myoglobin, creatine kinase, potassium and other proteins and ions into the bloodstream [1]. The breakdown products produced by myoglobin can results in kidney damage and the high levels of blood potassium can result in cardiac arrest. Severe muscle trauma can also cause damage and leakage of blood vessels, resulting in an increased level of pressure within the muscle compartments [2]. This…

Duchenne Muscular Dystrophy (DMD) is a rare single gene disorder affecting 1 in 3,500 boys. The muscles of the affected person weaken and waste away (atrophy), usually beginning in the lower limbs and then spreading to the upper body as the disease progresses (1). This disorder is caused by recessive mutations in a gene called dystrophin. The dystrophin gene is located on the X chromosome (Xp21.2). Because the X-linked disorder is recessive it occurs mostly in males because males who inherit the…

Mylan Pharmaceuticals has been in the spotlight lately, but not exactly in a positive way. The media and consumers have made it known that they don’t appreciate excessive price hikes in one of the many drugs Mylan produces. The EpiPen is designed for patients who have a severe allergic reaction to some substance or extreme cases of asthma attacks. Unfortunately for those that need the drug, prices have increased from $57 in 2007 to about $616 for a two-pack today—an increase of 1,080%. Just…

is important to do static stretching to warm up and loosen muscles prior and after your workout, but I have survived this long without it. I do warm up exercises prior to my workouts, which include jump rope, stairmaster, bicycle, light jog, row, or swim. I start every exercise routine with 10 minutes of one of those choices, and then move one to my workout routine. I find that those exercises help me get my blood flowing, and my muscles ready for my routine. I do not stretch at the end of my…
