Cardiac electrophysiology

The two main neck muscles are the sternocleidomastoid and the trapezius, and are responsible for the gross motor movement in the muscular system of the head, neck and shoulders. The sternocleidomastoid muscle is a paired muscle, located at the front and on each side of the neck. It is one of the largest and most superficial cervical muscles. The primary actions of the muscle are rotation of the head to the opposite side and flexion of the neck. The trapezius is one of the biggest shoulder and…

Duchenne’s muscular dystrophy is a hereditary issue portrayed by dynamic muscle degeneration and shortcoming that happens more in males. It is one of nine sorts of solid dystrophy. DMD quality that can be acquired in families in an X-connected latent style, yet it frequently happens in individuals from families without a known family history of the condition. The quality is the second biggest quality to date, which encodes the muscle protein, dystrophin. Young men with Duchenne solid dystrophy…

When you lift a heavy weight (be it yourself or a barbell), your muscles contract. That contraction begins when your nervous system sends a signal to your muscle fibers. When a movement is performed over and over again, and the muscle fibers repeatedly receive an identical signal, a more efficient neuromuscular motor pattern develops. The process by which neurons become more efficient is called myelination. Through regular practice of a movement, a fatty white substance forms a sheath around…

There are many different parts of skeletal muscles that are important to the function of the muscles. Each muscle is made up of a lot of muscle fibers. Each muscle fiber has a thin coating covering the fiber called the sarcolemma. The muscle fibers also have a cytoplasmic type substance called sarcoplasm. Sarcoplasm contains large amount of glycosomes and myoglobin. Myoglobin is a protein that stores oxygen inside the muscle fibers. The muscle fibers contain striations that are made up of…

The muscular system is the system of the body that contains smooth, skeletal, and cardiac muscle tissue. This system contains a variety of functions including movement of the body and of materials throughout the body, maintenance of posture, and heat production. Muscles are the only tissue in the body that have the ability to contract and therefore move the other parts of the body. The muscular system is important because without it, life would completely stop. Muscles produce not only…

With CPR and First Aid training you could learn how to bring someone back to life, help them stop choking, or more simple procedures such as making a tourniquet to stop bleeding. If CPR is performed close to a cardiac arrest, choking, or whatever it may be can triple a person’s chance of survival. “Cardiovascular disease is the leading cause of death in the United States” (Monette, Michael. 2012). If teachers take a stand to advise students to be bold and encourage…

Many people think that muscles are mainly just for being strong and fit, but muscles do much more than that. Muscles are cellular fibers that contract and retract on bones, causing movement. This allows people and animals to move from one place to the other. There are several different types of muscles, including fast and slow twitch muscles, skeletal muscles, striated muscles, smooth muscles, and more. Every muscle serves a purpose, and each is vital to a person’s well-being. Muscles work…

can monitor the electrical activity of your heart over longer periods of time. • Stress tests to see how exercise affects your heart rhythm. • Echocardiogram. This test uses sound waves (ultrasound) to produce an image of your heart. • Electrophysiology study. This is used to evaluate the electrical conduction system of your heart. TREATMENT Usually, no treatment is needed. You may be advised to avoid things that can trigger the premature contractions, such as caffeine or alcohol.…

muscle in a woman’s uterus or womb helps to push out the baby out of the mother’s body. Smooth muscles in the bladder give people the ability to hold in their urine and help excrete urine. The last main muscle cell is the cardiac cell, controls the beating of the heart. Cardiac muscles continually contracts (become smaller) and relaxes (becomes larger), pumping blood around your body 60 to 70 times a minute, 100,00 times a…

Saving Lives, Outside the Hospital (Informative Speech) Bradley Dryden, Western Governor's University General purpose: To inform Specific purpose: To inform the general public of the need and efficacy of compression-only cardiopulmonary resuscitation. Thesis statement: Any attempt to perform CPR is better then no attempt at CPR. I. Introduction Imagine this situation. You are at a family dinner. Everyone is enjoying conversation after the meal, and you notice uncle Leroy with a worried look…
