Muscular system
The muscular system is the set of all the muscles that make up the human body. It is an extensive system of muscles and nervous tissue, which is distributed all through the body. In total, the human body consists of approximately 650 muscles. The muscular system is divided into three types of muscle: cardiac muscle, smooth muscle, and skeletal muscle.
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 first basic function of the muscular system is movement, which is carried out by the skeletal muscles. The primary function of the skeletal muscle is to produce voluntary gross and fine motor movement. This set of voluntary muscles provides the forces that enable the body to move. A skeletal muscle links two bones across its connecting joint. When these muscles contract or sho...

...t something that patients can look forward to even with treatment. Physically, muscular dystrophy is a burden but it also affects the person’s social participation. Young children may not understand or want to play with children with muscular dystrophy. Also playgrounds may not be equipped with the adequate equipment to allow children with muscular dystrophy to participate.
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.
This report will explore the structure and function of skeletal muscle within the human body. There are three muscle classifications: smooth (looks smooth), cardiac (looks striated) and skeletal (looks striated). Smooth muscle is found within blood vessels, the gut and the intestines; it assists the movement of substances by contracting and relaxing, this is an involuntary effort. The heart is composed of cardiac muscle, which contracts rhythmically nonstop for the entire duration of a person’s life and again is an involuntary movement of the body. The main focus of this report is on skeletal muscle and the movement produced which is inflicted by conscious thought unless there is a potentially harmful stimulus and then reaction is due to reflex, as the body naturally wants to protect itself. Skeletal muscle is found attached to bones and when they contract and relax they produce movement, there is a specific process that the muscle fibers go through to allow this to occur.
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
Muscle is a very specialized tissue that has both the ability to contract and the ability to conduct electrical impulses. Muscles are classified both structurally as either striated or smooth and functionally as either voluntary or involuntary and. Muscle cells (myocytes) are elongated and classified as either striated muscle cells or smooth muscle cells depending on the presence or absence of regularly repeated arrangements of myofibrillar contractile proteins called myofilaments.
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 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
Every part of our body is a science. I never imagined the hidden science in the movements of the body. The science of kinesiology is the science of body movements. I grew up watching my grandma and the changes in her body as both of us got older, I could walk and balance properly while she lost it. I always felt bad when she was not able to get up and walk properly and as caring grandson I always gave her my hand. It was a great feeling for me to take care of her in her last days. Her difficulty in moving always pointed me to do something for her and I landed doing kinesiology- the science of human movements. I completed my high school at Cathedral High School in West Texas. I was an active member of National Honor Society as well as Spanish Honor Society. I held the treasurer position for one year in the society, which I felt proud of. I was not excellent at my academics, was just an average student struggling with the subjects of chemistry and anatomy. It is strange at one point of time suddenly when u come across a certain situation or an accident and u just realize your dream and...
Muscular dystrophy is a complex disease that has been around for many years. Although it was discovered in the 1830s there is constant discoveries about the disorder. (“New knowledge about Muscular dystrophy,” 2014 May 5) There are several research studies being done around the world to help find a cure. Here’s to hoping that a cure will be found and no more lives will be taken by this debilitating disease (“Muscular Dystrophy: Hope through Research,” 16 April 2014)
As you can see by the diagram, the muscles cover the entire body as does the integumentary system. They are responsible for movement. They are attached to the bones (skeletal system) and there are nearly 700 different ones. Each is made up of the muscle tissue, blood vessels, tendons and nerves. Each has a specific purpose. For example, the leg muscles assist in moving and bending the legs. The muscles make up nearly half of a person’s total body weight.
What is the musculoskeletal system? The musculoskeletal system is the system that provides support, mobility and stability to the body. The musculoskeletal system is made up of bones, muscles, cartilage, tendons, ligaments, joints, and other connective tissue that help support the body and organs. Without them our bodies would not be able to stand up or move and our internal organs would be vulnerable. Although the musculoskeletal system seems to be able to protect the body, sometimes the body is susceptible to an injury, disease, or malnutrition. When the body is exposed to these injuries, diseases, and malnutritions the musculoskeletal system is weakened.
There are three types of ways that the muscles move. The first one is an agonist. Agonist muscles cause a movement to occur through their own contraction. For example, the triceps brachii contracts during the up phase of a push-up (elbow extension). During the down phase of a push-up, the same triceps brachii actively controls elbow flexion while relaxing. It is still the agonist, because while resisting gravity during relaxing, the triceps brachii continues to be the prime mover, or controller, of the joint action. Agonists are also interchangeably referred to as "prime movers," since they are the muscles considered primarily responsible for generating a specific movement. This term typically describes skeletal
The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles
Isometric Exercises – Abdomen Isometrics uses muscle contractions to work with the natural function of muscles. Any elite athlete will tell you that Isometric exercises are useful when it comes to shaping and sculpting the muscles in your abdomen. These exercises are great for traditional workouts, as well as body building. Isometric exercises are an alternative to traditional sit-ups, and help by keeping the abdominal muscles rigid and strong, rather than in their natural relaxed state. 1.
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
The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
Support is a very important fuction as without the skeleton the body would have no means of staying upright as almost all of the body tissues are soft this helps gives the body structure. The Skeleton plays an important role in the protection of the organs for example the skull protects the brain and the ribcage protect the lungs.The skeleton assists in the movement of the body as the ligaments in the body attach bone to bone and the tendons attach muscle to bone. To create movement the muscular system and the skeletal system work together creating the musculoskeletal. The skeleton can begin to move once the muscles contract. The fifth function of the skeleton is the formation of joints, these are essential to create movement within the body. Muscle attachment allows the bones to move. This is done by the muscles attaching to the bones by tendons. Minerals such as calcium salts and phosphorus are stored in the bones. The final function of the skeletal system is the formation of blood cells; most of the blood cells for the body are produced by red bone
