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 (Shier, Butler, Lewis, 2009). The muscular system is divided into three types of muscle: cardiac muscle, smooth muscle, and skeletal muscle (p.212).
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. They range from extremely tiny strands such as in the muscle of the middle ear as large like in the muscles of the thigh (Martini, 2000). 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 connec...

...s it 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.
In this paper I will clarify the relation between the integumentary system and the skeletal system. During this paper I will address how the two systems work together to maintain homeostasis and what occurs when balance is not maintained between the integumentary and skeletal system. During this paper I will explain how osteoporosis is directly linked between both the integumentary and skeletal system and ways to prevent or yield this disease.
Within skeletal muscle there are extremely small structures that form the muscle and allow contractions and movement to occur (epimysium, perimysium, endomysium, fascicles, fiber, sarcomere, sarcoplasmic reticulum and t tubules). These structures all play a role in protecting, connecting and transporting substances throughout the muscle fibers. They are also the main contributors to movement.
Skeletal, smooth, and cardiac muscles play a vital role in the everyday processes that allow the human body to function. Without these muscles, everyday tasks and functions could not be conducted. Injury to these muscles could cause serious problems, however, these muscles have the ability to regenerate, repair, and fix multiple problems all by themselves. Repair and regeneration of a muscle are two similar, yet different things. Repair restores muscle continuity so that it can continue to function in the same way as before injury, but does not completely restore the pre-injury structure like regeneration (Huijbregts, 2001). Muscle repair and regeneration take place after an injury, after surgery, after atrophy, and even after working out.
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.

They support and bind tissue and organs together. Primary function is to support the body, allow motion and protect vital organ. The skeletal system and muscular system are two separate systems that function together. It provides movement, maintains posture, and body position. They work together through a series of impulses and signals communicated by the brain. In order for movement to happen, the nervous system signals the skeletal muscles to contract. When the muscles contract, it causes the attached bone to follow, creating movement. Bones and muscles are supported by connective tissue playing the role in structural
After the skin, there is a layer called the dermis. The dermis is a broad layer of fibrous and elastic tissue (made mostly of fibrillin, elastin, and collagen) which gives the skin its flexibility and strength. The dermis incorporates nerve endings, sweat glands and oil glands, hair follicles, and blood
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.
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)
When observing both cell types under a microscope several differences are obvious. Firstly, skeletal muscles are larger than smooth muscle cells (one muscle cell can be up to 100µm in length). They are also multinucleated whilst smooth muscle cells are uninucleate (Alberts et al, 2002: 961). Additionally, skeletal muscle cells appear to be striated, whereas smooth muscle cells do not show this banding pattern; but are instead smooth and tapered. The absence of this patterning in smooth muscle cells suggests that they consist of a less organised collection of contractile fibres (Silverthorn, 2007: 397). This banding pattern in skeletal muscles is known as the sarcomere.
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
Many other body system are interrelated to the musculoskeletal system, which including skeletal, muscular, nervous, and digestive and circulatory system. Receptors in the muscles provide the brain with information about body position and movement. The nervous system controls the contraction of the muscles. The nervous system regulates the speed at which food moves through the digestive tract. The smooth muscles of the walls of the digestive organs rhythmically and efficiently move food through out the digestive system into other parts of the body. The muscular system works closely with the nervous system.
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 human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
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
