Muscle Fatigue Case Study

Myasthenia Gravis (MG) is a chronic autoimmune disorder of the neuromuscular system part of the body. Chronic means persisting for a long time or constantly recurring. Autoimmune disorder is the confusion of the body’s immune system. The immune system form antibodies that mistakenly identify healthy tissue as foreign and then, the antibodies will attack and/or destroy healthy body tissue. Neuromuscular is the nervous system relationship with the muscles bring about body movement.

Myasthenia Granis is an autoimmune disorder affecting the myoneural function, it is characterized by varying degrees of weakness of the voluntary muscles, often it affects more men than women. It occurs when antibodies at the ACH sites impair transmission of the impulses across the myoneural function. Manifestations such as diplopia, ptosis and facial weaknesses are common (Hinkle &Cheever, 2014).

Nerves are responsible for the controlling the contraction of muscles, determining the number and the sequence and force of muscle contractions (Muscle Fatigue, 2015). The movements that are required for a force far below what a muscle is able to generate and with the exception of pathology nervous fatigue is seldom an issue. For extremely powerful contractions that are close to the upper limit of a muscle’s ability to generate force, nervous fatigue can be limiting factor in untrained individuals.

Myasthenia gravis (MG) is an autoimmune disease that affects nerve impulses to skeletal muscles. There are varying types of this disease and the symptoms can range from mild, a person having peripheral skeletal muscle weakness, to severe, a person having breathing problems (Sieb, 2014). Myasthenia gravis is diagnosed in 20 out of 100,000 people in the United States, and women are more likely than men to have the disease (Meriggioli and Sanders, 2012). This autoimmune disease can happen at any age, but women generally have an earlier onset than men; the mean age for females is 28 and 42 for males (Nair, Patil-Chhablani, Venkatramani, and Gandhi 2014). To better understand this disease this

Meta Description: Myasthenia gravis is a serious condition that can effect the nerves and muscles of dogs and cats.

John Stillman, a thirty-two year old gymnastics instructor, was presented to the clinic with complaints of muscle weakness in the face that comes and goes. Symptoms have progressed over the past two months to include tired jaw, difficulty swallowing, diplopia in the evening, increased weakness in his limbs and shortness of breath. Physically visible, John has mild ptosis in both eyelids and his smile is a bit off. Patient John Stillman portrays symptoms of Myasthenia Gravis (MG) meaning grave muscular weakness. According to Myasthenia Gravis Foundation of America, the most common form of MG is chronic autoimmune neuromuscular disorder, which can be seen by loss of strength in the voluntary muscle groups (2015). Much research has been done for Myasthenia Gravis, but there is still a lot of unknown information, such as a cure. In this study, one will learn what Myasthenia Gravis is, how it is tested, possible complications, and how it is treated.

Interval training is charactered by intensity, work duration and rest periods. It involves a short or long durations of high intensity exercise repeated with a specific amount of recovery. The training type improves athlete’s performance along with their cardiorespiratory fitness, VO2 max and improves exercise adaptations (Billat, 2001). Exercise intensities elevate ATP utilisation and restrict metabolic processes, increasing the level of blood lactate. The restriction of metabolic processes causes an increase in muscle fatigue. Therefore restoration of metabolic concentrations during recovery periods from intense exercise is important for optimal exercise performance (Edge, Eynon, McKenna, Goodman & Bishop, 2013).

The human body has various systems of how it is able to transmit signals across various tissues. One of the most important systems the body uses for this signaling is ion channels. Ion channels are found in every part of the body, and are specifically used to transmit ions across gradients. In skeletal muscle, these ion channels are used for muscle contractions that are coupled with action potentials and are initiated by depolarization of cellular membranes. In skeletal muscle this occurs by a single nerve impulse that travels through neuromuscular junction (NMJ) and along the surface of the sarcolemma membrane. The signal then enters radially inward along the transverse tubules which causes a conformational change of the calcium channels and releases Ca2+ from the sarcoplasmic reticulum, inducing a muscle contraction. In certain disorders caused by mutations of ion channels downstream of the NMJ, altered muscle contractions or muscle weakness may occur.

Myasthenia Gravis is a rare, but aggrieve autoimmune disease that was discovered by neurologist back in the mid 30’s. This disease is known for blocking the receptors that supply the body with the necessary proteins and signals the body need to preform adequately. Myasthenia has no particular race, gender, age group or living being that it would take as a host to destroy. Some neurologist believe MG can also effect dogs and other type for animals. The first sign of MG began with the eyes first. Then Myasthenia will move to the muscles structure of its host to break the volunteer muscles. Doctor believe around the age of 60 is when MG seem to be more active among males. No one knows why, maybe because our body are weaker a fragile doing this

Group B streptococcus (GBS) is one of the leading causes of pneumonia, sepsis, meningitis and death in the neonatal patient (1). Pregnant women who are carriers of GBS have the potential to spread the bacterium to their newborn infant via vertical transmission before delivery, during prolonged labour and premature rupture of membranes, or via post-partum exposure (1,2,3). The US Center for Disease Control (CDC) estimates that between 10-30% of women are GBS colonized. Approximately 50% of infants, whose mothers at 37 weeks test GBS positive and are untreated, become colonized (2). As the spectrum of maternal and fetal GBS infection may range from asymptomatic colonization to sepsis, careful management is necessary to help protect life and health (2). Through methods such as prenatal screening and prophylactic antibiotic treatment, the incidence of neonatal GBS has

A muscle strain is something people just by pass while working out. I’ve experienced it before, I thought nothing of it when it first happened. Most of the time people who don’t understand the body mostly think of it as a sore muscle but in reality, it is a damaged muscle or its attaching tendons. To repair a strain is easier then what people think. Mostly consist of icing and resting the strained muscle. Without any extra activities on that strained muscle, but I had to learn the hard way.

Fatigue is a symptom of anemia due to the lack of red blood cells to carry fresh oxygen from the lungs to the working organs and structures. For pernicious anemia, the onset is commonly slow and patients can ignore early symptoms. When the hemoglobin levels have dropped considerably, the patient will experience the more poignant symptoms such as; “weakness, fatigue, paresthesias of the feet and fingers, difficulty in walking, loss of appetite, abdominal pains, weight loss (McCance & Heuther, 2014).”

There are many steps involved in muscle contraction. The first being where the action potential starts in the brain and travels to the muscle where it meets at the neuromuscular junction. This is where a chemical synapse is formed. The motor neuron from the brain connects with the muscle fiber. Acetylcholine is a chemical neurotransmitter used at the neuromuscular junction that the motor neurons of the nervous system release in order to activate muscles causing contraction. There are diseases that wreak havoc on the connection at the neuromuscular junction; tetanus, botulism, and myasthenia gravis.

Myasthenia Gravis (MG) is an autoimmune neuromuscular disorder that is characterized by fatigue and exhaustion of muscle. The skeletal muscles is having different degrees of weakness and this occurs when nerve cells and muscle are not be able to communicate efficiently and becomes impaired. This impairment put a stop to the muscle contraction from occurring which can lead to muscle weakness. Myasthenia Gravis originally comes from the Latin and Greek words that means “grave muscle weakness’’. According to Osserman (as cited in Turner, 2007) MG is divided into four groups based on the severity of the disease - ocular myasthenia, generalised myasthenia of mild or moderate severity, severe generalised myasthenia, and myasthenic crisis with respiratory failure. The history of MG dated
