  • Creatine Monohydrate Research Paper

    Each year, Americans spend 1.5 billion dollars on supplements and vitamins designed to improve overall health and body function. While some products claim to have “miracle powers”, others are proven to be most effective. When it comes to athletic performance, most athletes look to supplements to aid in strength and muscle gains. Though some take non-effective, sometimes illegal supplements like HGH and steroids, others look to the more common legal supplements like creatine. Creatine is a…

  • Usain Bolt Research Paper

    Usain bolt is the fastest man in the world using a lot of force to propel him self over the finish line in record times even though his hight isn't the ideal hight to be a sprint he needs to be faster than any of the other athletes. When usain bolt runs he puts a massive amount of force into the ground. With each quick stride he takes he generates a huge amount of force.the ground produces the same amount of force to propel bolt forward. Usain would need more force to propel him forward because…

  • Muscle Contraction

    II.I How it is use? Muscle contraction requires the use of ATP molecules. Indeed, muscle cells are composed of contractile elements: sarcomeres. Muscle contraction is due to the slippage of myosin fibers on the actin fibers. For this, the head of the myosin binds to the troponin site of the actin filament. Then, an ATP molecule will bind to myosin to separate actin and myosin and thus allow its attachment to the neighboring troponin site due to hydrolysis of ATP in ADP + Pi. This creates a…

  • Frog Heart Lab

    Although human and frog hearts do not look the exact same, they do act very similar. Human hearts have four chambers: two atria and two ventricles. Contrarily, frog hearts have only three chambers: two atria and one ventricle. Frogs are helpful in scientific research of the heart and its many functions because human hearts can obviously not be used. In this case, the frog hearts are helpful in determining the effects of different chemicals on the heart. Certain chemicals and agents effect the…

  • Synovial Joint Case Studies

    Synovial joint consists of a joint capsule, a joint cavity and a layer of cartilage over the ends of two joining bones. These joints are lined with synovial fluid. The articular cartilage over the joint ends absorbs jolts as it acts like elastic and it also provides a smooth surface for the joints to move frictionlessly. This fluid also helps in lubricating and protecting the bones. Cartilage is softer and much more flexible than a bone. The major role of cartilage is to form a model for later…

  • Essay On Muscle Contraction

    “A muscle is a tissue composed of cells or fibres, the contraction of which produces movement in the body.” (Dictionary) There are three different types of muscle; voluntary skeletal muscle, involuntary smooth muscle and cardiac muscle. Muscles have many different functions within the body. One function of muscle is movement. It is the only tissue in the body which is able to contract and therefore can move more than other body parts. Another function is the maintenance of posture. The muscles…

  • Muscle: Location, Action, Shape, And Function

    Evaluate how the name of a muscle can distinguish its location, action, shape, and function. Select five different muscles to make this distinction. Depending on the anatomical position of the body part, certain prefixes, and suffixes are utilized in order to find its location verbally. These prefixes and suffixes can be described by the: size of the muscle, location of the muscles, direction of the muscle fibers, amount of origins, shape of a muscle, and location of a muscle origin/insertion.…

  • Wrist Joint Case Study

    The wrist or carpus is a highly mobile structure composed of many small bones and joints. In the anatomy of the human hand, a total of 13 bones form part of the wrist- eight carpal bones- scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitate and hamate; and five metacarpal bones which are joined along with two long bones of the forearm- the radius and the ulna (Platzer 2004). This complex system of articulations works in unison to provide a global range of motion for the wrist…

  • Muscle Contraction Research Paper

    Skeletal muscles are made of three different muscle fiber types. All muscle fibers are having varying amounts of mitochondria in them. Mitochondria helps the muscle be able to manufacture ATP for contraction. To differentiate between the three muscles is based on their make up. Slow oxidative (SO) or type one muscle fibers are composed with the most mitochondria to help them be fatigue resistant. SO muscle fibers stain the darkest because the enzyme targeted by the stain is most abundant in this…

  • Skeletal Muscle Training

    being done, the skeletal muscle will adapt differently to each type. The two most basic types of exercise are endurance and resistance training (Knuiman, 2015). The goal of endurance training is to improve aerobic power by conducting submaximal muscular contractions. Adversely, resistance training involves approximately maximal contractions occurring in short bouts. It also focuses on muscle hypertrophy, or the enlargement of muscle fibers (Knuiman, 2015). Due to this fact, skeletal muscle…
