Muscular System The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It functions of the muscular system are movement of the body, maintains posture, and circulates blood throughout the body, and fatigue. The muscles produce movement by pulling the bones as each muscle contracts. There is a low strength muscle contraction called tonic contraction and it enables one to maintain its body posture. When one has good posture it is better for the body to function. The heat production is when the body maintains a certain temperature and it is important because that is one of the main functions for the body to survive. For the body to maintain a normal body temperature the muscle fibers must contract to produce heat required to keep it normal. One disease that one can get in the muscular system is Cerebral palsy. Cerebral palsy is known as one of the most common congenital disorders. It impacts the balance and motor functions along with the posture. When there is brain damage to a child at a young age it being before it was born or after, it causes a loss of muscle tone. When they lose muscle tone it makes it difficult for the person to go on with their everyday lives and perform the normal tasks needed each day. The signs and symptoms that one may notice for the disease Cerebral palsy is that it can be one having problems with fine motor tasks like using scissors, or as intense as not being able walk or keep their balance. Patients may not be able to control their hand motions along with drooling. Then there are others that suffer from mental retardation and seizures. Cerebral palsy is a disease that cannot be cured but has numerous amounts of treatments for it. Patients that have Cerebral p... ... middle of paper ... ...ng is fine and sometimes check the chest for tumors. Once again, like cerebral palsy, there is no cure for myasthenia gravis. Although there is no cure there is treatments that allow going periods at a time without any symptoms. Some treatments for this disease includes making time to rest, use an eye patch for vision problems, and avoid any type of exposure to the heat. There are also medications that can be used to make symptoms better. People that have Myasthenia gravis live a normal life expectancy. There are some that experience remission but for some patients their life changes in a blink of an eye. Therefore they want to know their prognosis. What some may not know is that Myasthenia gravis does not get worse as you get older. If anything the symptoms start to go away. Patients are recommended to try different types of therapy to see which is best for them.
Myasthenia Gravis is an autoimmune neuromuscular disorder. The term "myasthenia" is Latin for muscle weakness, and "gravis" for grave or serious. It is characterized by random weakness of voluntary muscle groups. Muscle groups most commonly affected include the eye muscles, facial, chewing and swallowing muscles, and shoulder and hip muscles. It is typical for a myasthenic patient to have a flattened smile, droopy eyes and an ineffective cough due to weak expiratory muscles, are all also associated with MG. Most myasthenic patients usually don't complain of extensive feelings of fatigue. They experience localized fatigue in specific, repeatedly used muscles. Today, MG is one of the most thoroughly understood neurological disorders, which has lead to treatments, which enormously improves the length and quality of life of myasthenics.
There are 11 organ systems in the human body and each system has its own function. The Muscular system provides support and protection to other organs and tissue. It also helps in body movement and maintaining heat and body temperature. The digital source by Emma Bryce on “How your muscular system works” explains the types of muscles in the involved in the movement of body.
DMD also known as muscular dystrophy is muscular disease that occurs on young boys around age four to six. Muscular dystrophy is genetically transmitted disease carried from parent to offspring. This disease progressively damages or disturbs skeletal and cardiac muscle functions starting on the lower limbs. Obviously by damaging the muscle, the lower limbs and other muscles affected become very weak. This is ultimately caused by the lack dystrophin, a protein the body produces.
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.
For some types of MD, medication can help. Guys with Duchenne MD may be helped by a medicine called prednisone, and teens with myotonic MD might use mexilitine to relax muscles.
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...
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
Many people have heard the term cerebral palsy and may have a personal perception about the appearance and effects of this
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.
The first historical account of muscular dystrophy was identified by Sir Charles Bell in 1830. He wrote about a disease that caused weakness in boys that progressively got worse. In 1836 another scientist whose name is unknown reported about two brothers who developed muscle damage, generalized weakness. Also damaged muscle was replaced with fat and connective tissue. At the time the symptoms were thought to point to tuberculosis. During the 1850s reports of boys with progressive muscle weakness became more and more common. There were also reports of these boys losing the ability to walk and dying at an early age. In the next decade French neurologist Guillaume Duchenne gave and in depth account of 13 boys who had the most common ...
Some range from neuromuscular disorders to myopathies. Polymyositis is an example of a group of diseases that involves inflammation of the muscles or associated tissue, such as blood vessels that supply the muscle. Another type of disorder is muscular dystrophy which affect the muscle fibers. There are even metabolic muscle disorder that interfere with the chemical reactions involved in drawing energy from food. Whereas, neuromuscular junction disorders impaired transmission of the nerve signals to the muscles. Some disorders affect the nerve cells that supply the muscles. This disorder is known as a motor neuron disorder, commonly known as amyotrophic lateral sclerosis
According to Medical-Surgical Nursing: 7th edition, Myasthenia Gravis (MG) is an autoimmune disease that can be considered as a chronic neuromuscular disorder (Lewis et al., 2007, p. 1555). MG is caused by an autoimmune process in which “antibodies attack acetylcholine (ACh) receptors, resulting in a decreased number of ACh receptor (AChR) sites at the neuromuscular junction” (p. 1555). Due to the neurotransmitter’s inability to connect the muscles and the nerves, it is difficult for the muscle to contract. This disease basically causes muscle fatigue and therefore a detrition of muscle strength over time. (John Hopkins Medicine, n.d.) In many respects, it is like a satellite unable to detect a signal when it is blocked by interfering radio waves.
There are three distinct types of muscles: skeletal muscles, cardiac or heart muscles, and smooth muscles. Muscles provide strength, balance, posture, movement and heat for the body to keep warm.
Currently, the muscular dystrophy is incurable. Sometimes steroid therapy slows the progressive course of muscle weakness. Treatment is aimed at maintaining the overall health, mobility, and the quality of life as possible.
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.
