The Complexity of Muscles The human muscular system, like any other system in the human body, is very complex. All the moving parts (anatomy), and how they work together to perform specific actions (physiology). There is so much that can be done to help the muscles in your body perform strenuous activities before fatigue, before your muscles run out of the fuel required to continue to perform movements. The biggest question most young adults want to know is, how do you get bigger muscles? Or, why do I cramp during workouts? All these and more can be answers through the understanding of the anatomy and physiology of the human muscular system. First let’s go over four very important factors of the human muscular system. First being the primary function of the muscular system is movement for the body. The nervous system communicates with the muscular system, resulting in movement. Second is the five major properties of the muscular system beginning with 1) our muscle being excitable or irritable. 2) Our muscles are contractible. 3) Our muscles are extensible. 4) Our muscles have elasticity. 5) Last, our muscle system is adaptable. Third, there are five types of muscle movements. 1) Adduction, movement towards the body. 2) Abduction, movement away from the body. 3) Flexion, “movement in the anterior-posterior plane that reduces the angle between the articulating elements.” (Martini, F 230). 4) Extension, “occurs in the same plane as flexion, but it increases the angle between articulating elements.” (Martini, F 230). 5) Last is rotation. Fourth, there are three main …show more content…
Most people want to achieve hypertrophy. Hypertrophy is “an enlargement of the stimulated muscle.” (Martini, F 224) Another factor that can occur in your muscles is known as atrophy. “A skeletal muscle that is not regularly stimulated by a motor neuron loses muscle tone and mass.” (Martini, F 224) This leased to a decrease in muscle size and

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.
The musculoskeletal system offers support and stability for your body so we can properly function and move around. Different types of muscle within the muscular system include cardiac, skeletal, and smooth. The reason our bodies are capable of producing movement is because of the way our muscles contract. Our adult skeletal structure is made up of 206 bones that all differ in shapes and sizes. The composing parts that make up the system include the bones, joints, and muscles that all connect so we’re capable of moving. These components allow for our bodies to maintain a stable structure that can keep us upright. The axial skeleton refers to the skull, the vertebral column which supports the spinal cord, ribs, and sternum. It offers protections
The skeletal system assists the muscular system to provide movement for the body. Certain muscles that are attached to bones contract and pull on the bones resulting in movement.
The muscular system is an intricate system that if affected can seriously affect the quality of daily living as well as total life span. Covering the entire body the muscular system consists of skeletal, smooth, and cardiac muscle. And within the three muscle groups five basic functions are executed: movement, protecting vital organs, pumping blood, aiding digestion, and ensuring blood flow. None of these important tasks would be possible without a healthy and strong muscular system.
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
The muscular system helps the body with movement. Throughout the entire body, there are 600 skeletal muscles. In a way, the skeletal system and the muscular system work together; the nervous system tells the muscles to contract and the muscles move. Some of the functions of the muscular system are to move the body, support and protect the organs throughout the body.

I was able to gain knowledge about the different parts of the body which are important in the field of bodybuilding. I discover that there are main muscle groups and each of these muscle groups have different parts. For example, the main muscle groups would be the chest, back, arms, shoulders and legs. Now each of these main muscle groups have more that one part, your arms has biceps, triceps and a forearms. Each of these parts are made up or many more segments that can construct a list that can go on for a while. Gaining such a vast understanding of my body was thrilling. I was able to understand all the parts of my body. I am confident that I know almost every muscle group that is in the known human body. After learning about each individual muscle, I was then able to move on to the next step understanding how to train these individual muscle groups. I figured out that there are different routines that you have to follow in order to train each muscle. For example, your legs can be split into different muscles segments such as the quads, calves, and hamstrings. Once I isolated each muscle segment I was able to find workouts for each of them. For the quadriceps you would do workouts known as a barbell squat, lunges and reverse leg curls. Then after finding this out I had to
The musculoskeletal system is comprised of bones, joints, cartilage, tendons, ligaments, fascia and muscles. Together these body parts work to establish a framework that is the musculoskeletal system. This framework is what gives the body its shape, form, and figure. It stabilizes the body as well as supplies the structural support. The musculoskeletal body features not only provide a framework for your body but allows your ability to create movement. These movements are monitored by the musculoskeletal components which then determine your degree of flexibility. Overall the amount of energy your body uses comes almost entirely from these musculoskeletal functions. Which makes sense because it
Scientists, coaches, and athletes have recognized that periodized strength training promotes increase in skeletal muscle size, increase in force, and increase of the regenerating capacity of the muscle cells.

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.
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
