Building Chest MuscleIf you are interested in building chest muscle, this is just what you have been looking for. I will teach you about building muscle without weights, and with weights to develop a massive, ripped chest. There are a few different ways to go about building chest muscle, so let’s cover that first. One way is to lift very heavy weights in good form for 5 to 12 reps per set. Another way is to do a large volume of work with lighter weights, or without weights at all. Some people…

a.) Concepts: • Exercise Strengthens Muscles • Exercise helps keep us healthy • Exercise your weight down. Learning outcome: At the end of this activity the children would learn that exercise is beneficial for us our bodies and our health, by making us stronger and maintaining our weight. Expectations: The children would know basic exercise positions. b.) Common Core Standards: The common core standards were met by having the children pass around a beach ball. Which had the…

The ability for muscles to contract and shorten to produce movement lies within its structure at a cellular level. The muscle organ is surrounded by a fibrous connective tissue called the epimysium, continuous to the perimysium, which separates the organ into small bundles called fascicles. Each fascicle can be further separated into muscle fibers by the endomysium. The plasma membrane of an individual muscle fiber is called the sarcolemma, which plays a major role in generating an action along…

The muscle has amazing cells structures in the body. Because every part of our body acts as a working machine all organs of the body are equally significant. The skeletal muscle in the body is a very important portion of the body. When people think of muscles, they usually think first of voluntary movement, but that is only part of the story. Muscles are literally everywhere in the body. Throughout the body, there are muscles in the eye, heart, limbs, tongue, throat,…

There are many different parts of skeletal muscles that are important to the function of the muscles. Each muscle is made up of a lot of muscle fibers. Each muscle fiber has a thin coating covering the fiber called the sarcolemma. The muscle fibers also have a cytoplasmic type substance called sarcoplasm. Sarcoplasm contains large amount of glycosomes and myoglobin. Myoglobin is a protein that stores oxygen inside the muscle fibers. The muscle fibers contain striations that are made up of…

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…

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. The gastrocnemius muscle was kept moist in…

important organs in the human body are muscles. Muscles usually make up 30-50% of the body and are responsible for producing skeletal movement, maintaining body position, and regulating body temperature. In a lab, the process of muscle contraction was investigated by exploring the sliding filament theory. An experiment was conducted to determine whether muscle length played a role in the amount of force a muscle produces. In order to fully understand how a muscle contracts, it is necessary to…

Muscle cells play a very important role in movement of our body. There are three types of muscle cells in vertebrates: skeletal, cardiac and smooth. We are mainly going to be concerned with skeletal muscle for this particular experiment. The skeletal muscle is responsible for the voluntary movement of whole body or body parts, manipulation of external objects, support for our skeleton (Sherwood, 2010, p257). Skeletal muscles have a striated structures of alternating light and dark bands…

Cardiac Muscle fibres are long cylinder shaped cells that usually have one or two nuclei, they are centrally located within the cell. The end of the fibres are split into a number of small branches in which the ends of which connect to similar branches of adjacent cells giving a three dimensional cytoplasmic connection network throughout the tissue. In between the muscle fibres, there is a delicate connective tissue, similar to the endomysium of the skeletal muscle which supports the extremely…
