Gastrocnemius muscle

introduction of this lab report discussed and elaborated how muscle contraction is an intricate and precise step-by-step process in the body. The concepts outlined at the introduction intertwine with the experiments performed in this laboratory. The experiments aimed to showcase the physiological cause and effect of skeletal muscle response towards various settings. For instance, the first experiment demonstrated spatial summation through the form of muscle recruitment. The cause of this…

Lab 3: Stimulus strength vs. muscle force production Introduction: The goal of this lab is to determine the relationship between stimulus amplitude (strength) and the contractile properties (i.e. force) of the frog gastrocnemius muscle. Skeletal muscle is composed of bundles of muscle fibers called myofibers. These fibers are themselves composed of myofibrils, which are comprised of the ordered arrangement of actin and myosin. These proteins slide past each other in the presence of calcium…

One thing that many living things require is the need for muscles in order to function. Humans are composed of more than half their body weight of muscle (Saunders, 2016). Muscles are the building blocks of an abundant amount of functions. For example, muscles are required in order to help many organisms eat, protect themselves, most movements, etc. The basic unit of muscles is referred to as a sarcomere, and when it contracts it excretes a force. The contraction is the result of the interaction…

we have only one type of muscle in our bodies that help us with all different types of tasks, however; not only do our bodies have different muscle types, they also contain different muscle fibers that are used for different activities. Skeletal muscle contain three types of muscle fibers: slow twitch, fast twitch oxidative, and fast twitch glycolytic. Most muscles in our bodies have different combinations of these muscle fibers, although our body recruits different muscle fibers for different…

The concepts outlined at the introduction intertwine with the experiments performed in this lab. The experiments aimed to showcase the physiological cause and effect of skeletal muscle response towards various situations. For instance, the first experiment demonstrated spatial summation through the form of muscle recruitment. The cause of this reaction was due to the…

The human body is composed of muscle which are responsible for body movement. Muscles in found in the human body attach to the bones of the skeletal system, in a human body there are “700 individual muscles that make up part of a person’s weight and the muscular system. Each of these muscles are separate organ which are made up of skeletal tissues, nerves, blood vessels and muscle tissues. Muscle tissues are found throughout the human body, inside the heart, the blood vessels and the digestive…

extent, in that increasing stimulus strength will increase the force generated by the gastrocnemius muscle and visa versa till 0.2V, where the force germinated starts to decrease. As shown in Table 2 and Figure 2, the strength of the stimulus started from 0.00 V to 1.00V with 0.05 V and 0.10V intervals. At 0.10V the force generated by the muscle increases rapidly from 0mN to 288.33mN. The force generated by the muscle continues to increase to 699.99mN at 0.15V until the stimulus strength reaches…

knowledge of twitch recruitment in skeletal muscles. As the stimulus voltage increase, more motor units were activated increasing contraction force. Our results mean that that function organism’s skeletal muscles are able to recruit motor units to make large powerful body movements. Skeletal muscle length-tension relationship: The maximum contraction force, 0.8102 N, was recorded when the gastrocnemius muscle was stretched by 2 mm. As the gastrocnemius muscle was stretched past 2 mm the…

2007). There is an innumerable amount of physiological benefits of exercise such as to combat health conditions and diseases. Regular physical activity can improve muscle strength and boost endurance during day life tasks. Exercise can also help to prevent weight gain, promote the loss of weight and supports in other to gain muscle fitness among a wide variety of other benefits. A lot of research have been done of these physiological benefits of exercise, nevertheless physical…

Revolutionizing the Fitness World Blood. Sweat. Tears. In the world of athletics, these three little words are the epitome of being an athlete. These words are written on the walls of many gyms, weight rooms, and posted on the inside of athlete 's lockers across the world. These words are related to sports such as volleyball, basketball, football, and soccer, just to name a few. CrossFit is changing the world perception of athleticism, and what it means to be an athlete. Also, it is redefining…
