Muscle atrophy

Spinal Muscular atrophy (SMA) is a group of diseases that result in progressive muscle deterioration and neuromuscular failure. As it is an inherited autosomal recessive disease meaning the sufferer must have both defective survival motor neuron (SMN1) genes, from each parent, to have the symptoms. There are five subtypes of SMA, categorised by the age at which the symptoms begin to appear, with type I, II and III occurring in childhood are more severe than type IV, which appears in later…

Dystrophin is a protein that is located in muscles that work with movement. The job of Dystrophin is to produce muscle proteins that protects the skeletal, cardiovascular and nervous system. Dystrophin plays an important role in protein complex that work together to strengthen muscle fiber and help prevent injuries. It also plays a role in cell signaling between proteins and chemical signals. However its main job is connecting and weighing down each structural framework between proteins and…

dystrophies (MD) are diseases that causes muscle mass loss and weakness (this is normally in children but can happen in adults). This is caused by abnormalities in genes that interfere with proper production of protein to form healthy muscles for voluntary movement. When the brain sends signals to a muscle to contract, it goes through the spinal cord and peripheral nerves to the neuromuscular junction, releasing the chemical acetylcholine that triggers muscle contraction. From here,…

together. So in other words, they act as ligands. This allows for more of the muscle tissue cells to be produced by the body. How Does it Work? SARMS in (INSERTCITY, INSERTSTATE) are said to be about 200% better at increasing muscle mass than plain testosterone shots can because of the way that they specifically target muscle cells and increase the amount of androgen in the body. Testosterone can also link with muscle receptors, but it has a lot of side effects to taking it. SARMS supplements…

whole life. From softball and soccer in high school to then competing in collegiate waterskiing, it wasn’t until a waterskiing accident where I found muscle therapy: a deviation from massage and chiropractic therapy. In my own words, it’s as if a physical therapist, chiropractor, and a massage therapist combined their practice a named it muscle therapy. The injury I sustained was a sprained meniscus, a thoracic strain, and thoracic sprain from a fall off a waterski ramp. I was originally…

ABSTRACT: Muscle hypertrophy refers to increase in muscular size caused by expansion or increasing count of myofibrils (hyperplasia) within skeletal muscles. Resistance-based training causes microtrauma within myocytes of target muscles. Damage to muscle cells induce activation of myosatellite cells, which proliferate as myoblast [1]. Myoblasts differentiate and recover damaged cells as they fuse with the tissues, making the cell more durable than the original state. Satellite cells may…

skeletal muscle mass and metabolic capacity is extremely important for human health and quality of life (Wolfe RR 2006). Skeletal muscle has distinct metabolic and contractile properties that can be influenced by nutrients uptake, microenvironment, and contractile activity. Plasticity and heterogeneity have also been shown to be hallmarks of skeletal muscle as shown by muscle morphology, fiber type, and oxidative capacity. Age, disuse, fasting and various degenerative diseases alter skeletal…

Fitness Advice to Ignore 1) ''Doing crunches and working on the abs machine will make you lose belly fat.'' - Crunches and abs machine will help strengthen your midsection muscles and will also improve your posture. Great! Now you have strong midsection muscles.. But being able to see them and tone your waist actually depends on your overall body fat percent, actually fat comes all over the body. Unfortunately spot training doesn’t burn fat, when you lose weight you are unable to choose the…

disease after Lou Gehrig, a great American baseball player whose career unfortunately ended abruptly due to this incurable degenerative disease. ALS is the deterioration of motor neurons in the brain and spinal cord that leads to muscle weakness. This significant decrease in muscle strength eventually becomes paralysis, and the majority of those with this awful disease die from respiratory failure. This is the most common neuromuscular disease and affects 12,000 people annually and about 4 out…

Introduction Myasthenia gravis is a neuromuscular autoimmune disorder that affects the skeletal muscles in the body. This disorder is mainly characterized by periods of weakness in the body. The Latin meaning for myasthenia gravis is grave muscle weakness (Lewis 2007). In the United States the prevalence rate is 14 per 100,000 (Lewis 2007) myasthenia gravis can affect any age, but normally it affects people over the age of 50 (Lewis 2007) The mortality rate from myasthenia gravis…
