The purpose of this experiment was to measure the tension, or force, produced by interacting filaments in a muscle fiber. In order to test this, a subject had three electrode disks located on their forearm. These disks were connected to a computer monitor which traced the EMG records and the Force trace of their muscle contraction. Data was observed while the subject changed their hand movement in different ways including wrist positions such as fully flexed, partial flex, neutral, and extended measured through the use of a hand dynamometer. In our observations we found that the Mean Rectified EMG increased in correlation with wrist flexion. In addition, after the wrist hit neutral and extended the opposite way

    There are three types of muscles in the human body: cardiac muscle, smooth muscle and skeletal muscle. For the purpose of our lab we will be focusing only on skeletal muscle. Skeletal muscle is the only voluntary muscle tissue found in the human body. They're attached to bones by tendons and are responsible for all the movements that are consciously controlled such as writing, walking, running, etc. [1].…

    The participant then record the amount of bicep curls done in the minute and put the weight down for a minutes rest. the participant took this time to shake out or stretch the muscles that were being used. After the minute of rest the participants were asked to pick up the weight and were asked to do as many full extension bicep curls as they can in a minute. This minute on minute off set up was repeated for a total of 5 times. Once all 5 participants had lifted for a total of 5 minutes on with 5 minutes of rest, then the average of each rep was calculated and the amount of change recorded.…

    1. The number of muscle fibers that are innervated by a motor neuron is dependent on what muscle it is. Fine motor movements, such as typing, would need only a few muscle fibers. This means that the thumb has only a few fibers, but the thigh, back, and biceps have many. These need a lot more force to be exerted, which is why they need more muscle fibers.…

    This means that the bigger muscles, which are the biceps will produce more force concentrically than eccentrically. The force produced by the biceps causes larger values in the EMG amplitude concentrically. The values that were obtained eccentrically produced a lesser force to prevent hyperextension of the arm and or elbow. The eccentric values are lesser compared to the concentric values. 3.…

    To modulate swelling and pain, transcutaneous electronic nerve stimulation (TENS) will be given to the client before each exercise session and to stimulate muscle activities from hypotonicity kinesiotype (KT) will be advised to wear when the client is not in therapy. The study of Sbruzzi, Silveira, Silva, Coronel, and Plentz (2012) found the effectiveness of pain modulation with the use of TENS. It should not be used while in the use of external fixator because it can cause skin to burn, fetal if a patient with a pacemaker (Poole, 2008). Xavier’s preferred…

    The muscle strength and reflex lab uses the involvement of two subjects to demonstrate the electrical properties of muscles and their motor neurons. With the relative strength and electrical activity of the dominant forearm, the observed data showed how the dominant forearm will average a higher force due to the amount of strength that arm may or may not have, and the amount of receptors that contract in unison. Supporting our second hypothesis, the non-dominant forearm resulted in a higher fatigue rate than the dominant forearm. This demonstration shows how the dominant arm with larger diameter fibers will be more likely to have more mitochondria and myofibrils causing the longer fibers to fatigue. There may also be a case where the dominant…

    The goal of this experiment is to understand muscle cell development by studying the proliferation and differentiation progress of C2C12 cells, which are myoblast line isolated from the thigh muscle of adult mice that can be induced to differentiate into skeletal muscle-like cells. C2C12 cells have been subcultured under conditions such as high serum media to maintain their undifferentiated state before they reach 100% confluency. Once the cells reached 100% confluency, they will turn on muscle specific gene such as MyoD that will promote expression of p21 to block cell cycle and will drive differentiation into myotubes. Complete differentiation to myotubes requires shifting the serum to 2% horse serum in the media to slow down the proliferation progress. In this experiment, we will plate the C2C12 cells in three different densities on one 6-well plate and two 8-chamber slides.…

    A single frog leg that was severed from the body at the hip joint was dissected to isolate and expose the gastrocnemius muscle. The gastrocnemius muscle was first separated from the tibiofibula bone, but left attached to the knee and the Achilles tendon. A 15 cm long piece of strong thread was tied tightly around the Achilles tendon of the heel of the frog for later attachment of the muscle to the force transducer equipment. The Achilles tendon below the tied string was then severed and the tibiofibula and femur bones were cut away and removed.…

Flexing in the mirror for self-confidence to building muscle for impressing the ladies, little do these individuals realize how their muscle works while they pump the iron. The muscular system is the network of tissues that help controls movement throughout the body using contraction and relaxation of different muscles. This system is divided into two classes, skeletal (voluntary) and smooth (involuntary).…
