Recommended: The role of muscles in the human body

Muscles are very important to the body. Muscles also do a lot for your body. They pump blood through your body, they help you lift heavy objects, and most of all they help your body in almost every way. Muscle is a body tissue that can contract and produce movement (Merriam-Webster Dictionary). Muscles are like the engine of the body; they turn energy into motion. Muscle tone isn’t as important as muscles, but it is very good for the body. Then there is muscular strength, which is a component of physical fitness which is just like muscle tone (DifferenceBetween.net. June 2, 2010 ) Muscle strength is a persons ability to exert force on physical objects using muscles (

A bundle of many cells is what makes up a muscle, and that is what also makes up a fiber. Compared to cells in your body muscle fibers are big. Muscle fibers contain many myofibrils. Myofibrils are cylinders of muscle proteins , and those muscle proteins allow muscle cells to function (Craig Freudenrich, Ph.D.). In the picture below you can see what a muscle fiber looks like and you can also see what myofibrils look like (Daydream).

Muscle contraction is a long process. It goes through many different steps. First, an electrical signal, action potential, travels down a nerve cell, causing it to release a chemical message, known as neurotransmitter,into a small gap between the nerve cell and muscle cell. This gap is called the synapse.The chemical message, neurotransmitter, crosses the gap, and attaches to a protein called a receptor on the muscle-cell membrane and causes an electrical signal, action potential, in the muscle cell.The chemical signal, action potential, spreads quickly along the muscle cel...

tone, and muscle strength because vitamin C is responsible for the health of the blood

vessels, which support the muscles needs for oxygen and nutrients (shape).

The best way to increase muscle strength is to lift weights. That is the quickest and best way to increase muscle strength. The best weight lifting strategies to gain muscle strength are squats, bench presses, military presses, barbells, deadlifts, power cleans, chin ups, and pull ups.

Muscles are very confusing, but once you get the physics of them, they are quite

interesting. There are so many different kinds of muscles and so many different types. I wonder what scientists will find next about muscles and muscle strength? I also wonder how fast you can build muscle strength or long it would take?

    In the beginning phases of muscle contraction, a “cocked” motor neuron in the spinal cord is activated to form a neuromuscular junction with each muscle fiber when it begins branching out to each cell. An action potential is passed down the nerve, releasing calcium, which simultaneously stimulates the release of acetylcholine onto the sarcolemma. As long as calcium and ATP are present, the contraction will continue. Acetylcholine then initiates the resting potential’s change under the motor end plate, stimulates the action potential, and passes along both directions on the surface of the muscle fiber. Sodium ions rush into the cell through the open channels to depolarize the sarcolemma. The depolarization spreads. The potassium channels open while the sodium channels close off, which repolarizes the entire cell. The action potential is dispersed throughout the cell through the transverse tubule, causing the sarcoplasmic reticulum to release

    For muscles to contract then there must be a presence of calcium within the fibers as it connects with troponin protein and orders tropomyosin to clear the binding sites to allow myosin to attach to these sites, which allows the muscle to contract and produces movement. Without all of these elements working in sync then the function of skeletal muscle would no longer work or even exist.

This functions allows for quick reflexes and the partial contraction, which is always in an active state, maintains balance and posture. Muscle tone keeps the muscles healthy and generates heat. “If the nerve to a particular muscle is damaged, it may no longer be able to stimulate the muscle contractions necessary to maintain muscle tone and the muscle will become flaccid and eventually it will deteriorate”(2). The tone of such muscles is not defined by matching against the muscles that are resisting, but the passive state that exhibits enervation without

    Cardiac muscle is a type of involuntary muscle found only in the walls of the heart, specifically the myocardium. Cardiac muscles contract automatically to tighten the walls of the heart in a rhythmic fashion. The heart beats nonstop about 100,000 times each day. Smooth muscle is a type of involuntary muscle found within the walls of blood vessels such as in small arteries and veins. Smooth muscle is also found in the urinary bladder, uterus, male and female reproductive tracts, gastrointestinal tract, and the respiratory tract. Skeletal muscles are voluntarily controlled and are attached to bones by tendons. Skeletal muscles also vary considerably in size and shape. They range from extremely tiny strands such as in the muscle of the middle ear as large like in the muscles of the thigh. The three individual muscle types also serve five main functions. The five basic functions are movement, organ protection, pumping blood, aiding digestion, and ensuring blood flow.

    The musculoskeletal system is made up of bones, muscles, cartilage, tendons, ligaments, joints and other connective tissue that supports and binds tissue and other organs together. Each muscle is a discreet organ constructed of skeletal muscle tissue, blood vessels, and nerves. Did you know there are roughly 600 organs that make up the muscular system? They include the cardiac muscles, smooth muscles, and skeletal muscles to name a few. The heart is the cardiac muscle. Smooth muscle are the tissues that line blood vessels and organs, such as the stomach and intestines. The skeletal muscles, which are the most well known and familiar of the muscle organ system, helps hold the skeletal frame work together. They make up bout 40 percent of the

    Upon stimulation by an action potential, skeletal muscles perform a coordinated contraction by shortening each sarcomere. The best proposed model for understanding contraction is the sliding filament model of muscle contraction. Actin and myosin fibers overlap in a contractile motion towards each other. Myosin filaments have club-shaped heads that project toward the actin filaments.

    Vitamin C also known as ascorbic acid is needed for growth and maintenance of healthy tissues, especially skin, blood vessels, bones, gums, teeth. Vitamin C aids in resistance against infection and healing of wounds. It also helps the body absorb iron from food. Vitamin C can be found in green vegetables, potatoes, tomatoes and citrus fruits such as oranges and lemon. A lack of vitamin C can cause scurvy, iron deficiency and poor wound healing. A healthy diet should include a high amount of vitamin C because the human body cannot produce its own vitamin C.

    Cardiac muscle is a type of involuntary muscle found only in the walls of the heart, specifically the myocardium. Cardiac muscles contract automatically to tighten the walls of the heart in a rhythmic fashion (pp.212-216). The heart beats nonstop about 100,000 times each day (p.18). Smooth muscle is a type of involuntary muscle found within the walls of blood vessels such as in small arteries and veins. Smooth muscle is also found in the urinary bladder, uterus, male and female reproductive tracts, gastrointestinal tract, and the respiratory tract. Skeletal muscles are voluntarily controlled and are attached to bones by tendons. Skeletal muscles also vary considerably in size and shape.

  • Synaptic Transmission

    572 Words  | 2 Pages

    Synaptic transmission is the process of the communication of neurons. Communication between neurons and communication between neuron and muscle occurs at specialized junction called synapses. The most common type of synapse is the chemical synapse. Synaptic transmission begins when the nerve impulse or action potential reaches the presynaptic axon terminal. The action potential causes depolarization of the presynaptic membrane and it will initiates the sequence of events leading to release the neurotransmitter and then, the neurotransmitter attach to the receptor at the postsynaptic membrane and it will lead to the activate of the postsynaptic membrane and continue to send the impulse to other neuron or sending the signal to the muscle for contraction (Breedlove, Watson, & Rosenzweig, 2012; Barnes, 2013). Synaptic vesicles exist in different type, either tethered to the cytoskeleton in a reserve pool, or free in the cytoplasm (Purves, et al., 2001). Some of the free vesicles make their way to the plasma membrane and dock, as a series of priming reactions prepares the vesicular ...

  • Muscle Contraction Essay

    1049 Words  | 3 Pages

    The contraction of a muscle is a complex process, requiring several molecules including ATP and Cl-, and certain regulatory mechanisms [1]. Myosin is motor protein that converts chemical bond energy from ATP into mechanical energy of motion [1]. Muscle contraction is also regulated by the amount of action potentials that the muscle receives [2]. A greater number of actions potentials are required to elicit more muscles fibers to contract thus increasing the contraction strength [2]. Studied indicate that the larger motor units, which were recruited at higher threshold forces, tended to have shorter contraction times than the smaller units [3]. The aims of the experiment were to reinforce the concept that many chemicals are required for skeletal muscle contraction to occur by using the rabbit muscle (Lepus curpaeums) [2]. In addition, the experiment was an opportunity to measure the strength of contraction and to observe the number of motor units that need to be recruited to maintain a constant force as the muscles begin to fatigue [2]. Hypothetically, the rabbit muscle fiber should contract most with ATP and salt solution; and the amount of motor units involved would increase with a decreasing level of force applied until fatigue stage is reached.

  • Good Nutrition Is More Important Than Exercise

    A lot of people are trying to build muscles in their body by working out. They work out by lifting heavy weights. However, when working out to building muscle, one needs to consume healthy foods and more proteins. After finishing a workout, the muscles in the body have microscopic tears to form in the fiber and connective tissues. This will cause the muscles to be tired and damaged. To repair the muscle, consume healthy foods and more protein. When one get enough foods in the body, the muscles will use the nutrients from the foods consumed and slowly rebuild, resulting in muscles in the body to increase size, strength, and muscle capacity. When I was in grade 9, I started to lift weight and I was new to it. After a few days of working out my body was experiencing any change. I realized that the reason my body was not experiencing change is because of what I was eating. I was not eating much protein and healthy foods. Later I started to eat foods that contain high protein and then I started to experience change, my muscles were getting bigger and stronger. Foods that contain high in protein can help to build muscles such as cottage cheese, chicken breast, whole eggs, canned tuna, etc. So therefore, having enough protein is the main key in order to build
