The Muscle System allows moving by contracting and releasing it self as what happens when you flex. Our Nervous system controls the muscle system even though some muscles like cardiac muscle move completely automatically. There are three distinct types of muscles: skeletal muscles‚ cardiac or heart muscles‚ and smooth (non-striated) muscles. Muscles provide strength‚ balance‚ posture‚ movement and heat for the body to keep warm.The Skeletal System is of both fused and separate bones connected and

Definition: Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions against a resistance for an extended period of time. he combination of strength and endurance results in muscular endurance - the ability to perform many repetitions against a given resistance for a prolonged period of time (1). It is a crucial element of fitness for athletes such as distance runners‚ swimmers‚ cyclists and rowers. It’s also important for success in many team sports like

Body in Action – Muscular System Roughly 40% of your body mass is made up of muscle‚ the key purpose of which is to move the bones of your body. In this assignment muscle movements and short and long term responses to exercise will be looked at. Types of Muscle Within the body‚ there are three different types of muscle. 1. Cardiac Muscle 2. Skeletal Muscle 3. Smooth Muscle Cardiac Muscle This is specialised muscle of the heart (BTEC National Sport Book 1). This is an involuntary type

Muscular System: Muscle Metabolism 1. List the three roles of ATP in muscle contraction: 1. _Energize the power stroke of the myosin cross bridge. 2. _Disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke. 3. _Energizing the calcium ion pump. 2. The potential energy in ATP is released when the terminal high-energy bond is broken by a process called hydrolysis. Write the end products of this process: ATP (+ H2O) (

Case Study 1. Dunchenne muscular dystrophy is a genetic disorder due to progressive weakness and degeneration of muscle cells over time‚ discovered by Guillaume Duchenne. 2. What you may notice under microscopic view is a mass majority of adipose tissue‚ rapid growth of Endomysium connective tissue‚ and deterioration of muscle cells 3. Being diagnosed with the disease would show pelvic muscle being effected first. Early signs of muscular dystrophy would be fatigue or weakness in the gluteal

causing muscle fibers to breakdown into the bloodstream. This has a toxic effect on the kidneys and could be avoided in many cases. Dialysis as well as natural remedies can correct the disease if caught at an early stage. Muscular system diseases include muscle pain‚ weakness in the muscles and paralysis. There are various causes‚ for example hormonal disorders‚ auto-immune problem‚ genetic factor‚ infections‚ cancer or misuse of the muscle. One such disease of the muscles is
