Cardiac muscle

Creatine kinase (CK) is a well-known marker for muscle tissue damage and can be measured in an athlete’s blood serum. A study assessed muscle damage in sixteen of the world’s best ultra-runners during the 2012 Western States Endurance 100-mile run. Blood samples were collected the morning of, immediately after, as well as one and two days post…

bones and hold them in place. Your skeletal system is also responsible for the storage of cells, and your bones help protect major organs, like your heart. Muscular - There are three types of muscle in the human body, skeletal muscle, which helps with voluntary movement and is connected to bone. Smooth muscle, helps pass…

Dystrophin is a protein that is located in muscles that work with movement. The job of Dystrophin is to produce muscle proteins that protects the skeletal, cardiovascular and nervous system. Dystrophin plays an important role in protein complex that work together to strengthen muscle fiber and help prevent injuries. It also plays a role in cell signaling between proteins and chemical signals. However its main job is connecting and weighing down each structural framework between proteins and…

is progressive disease of the muscle, caused by defective or absent glycoprotein, dystrophin, in the membrane of the muscle wall. Dystrophin reinforces the myotube membrane skeleton by increasing its stiffness, thus a lack of dystrophin causes substantial reduction in muscle stiffness. Symptoms include ambulation difficulties, hyperopia and gross motor milestone delays in infants and children, calf hypertrophy, an imbalance in lower limb strength, and diminished muscle tone. It occurs in 1 in…

puberty, there are no differences among sexes in relation to the size of the heart, but after puberty the “absolute heart mass is greater in men than in women by about 15-30%” (Leinwand, 2003). Also, healthy young men and women have no difference in cardiac index, but have alterations in cardiovascular stress; “men response by increasing mainly vascular resistance,…

Bradyarrhythmias - occurs when the heart rate is slower than normal (lower than 60 bpm) . if the heartrate is too slow not enough blood reaches the brain (this can cause you to pass out). Bradyarrhythmias is due to the flawed cardiac conduction system (group of cardiac muscle cells in the walls of the heart that send signals to the heart causing it to contract) at the level of the atrium or atrioventricular. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is…

There are about 700 types of muscles within the human body that aid the body with movement while a few also helps with stabilizing the bones (Allen and Harper 2014). Skeletal, cardiac, and smooth are the three types of muscular tissues found within the body (Tortora and Derrickson 2014). The heart is made out of cardiac muscle tissue and that is striated (Tortora and Derrickson 2014). The walls of the hollow organs of the human body are made with smooth muscle tissues that are non-striated…

Muscular Dystrophy is a disease which leads to muscle weakness and loss of strength. This disease begins at an early age and symptoms appear during the early stages of childhood and it progressively destroys and deteriorates the muscles. Among the many types of Muscular Dystrophy, the most common and severe form is Duchenne Muscular Dystrophy (DMD). Duchenne Muscular Dystrophy is an inherited disorder and unlike other forms of Muscular Dystrophy, it is the one that develops and worsens quickly…

progressive muscle degeneration (Muscular Dystrophy Association). Muscle weakness appears in early childhood and progressively worsens; children with DMD are generally wheel-chair dependent by adolescence. Along with the DMD affecting the skeletal system, the cardiac muscles are also affected and result in cardiomyopathy. Cardiomyopathy is a heart disease where weak cardiac muscle prevents the heart from pumping blood efficiently. Typically, males with DMD live into their twenties before the…

Some of these symptoms don’t even happen right away, but it takes time for it to kick in. When a child is going through their early childhood stage, there are some symptoms are going to be discovered, for example, the first effect happens at the muscles of the tips, pelvic area, thighs and shoulders. The calves may end up being enlarged, and the child could be clumsy and fall down easily. They also have a hard time climbing the stairs, getting from the floor, or even running. In order for them…
