Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209654763 2017-11-23 10:10:38 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209654763 typical exam question: katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209656429
Cardiac muscle (heart muscle) is an involuntary, striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.

Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control]]> 2017-11-23 10:17:17 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209656850 http://kidshealth.org/en/kids/msquiz.html katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209658391 2017-11-23 10:22:48 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209658391 Neuromuscular Muscle Diseases A neuromuscular disease is essentially a neurological problem that affects a single muscle or a group of muscles, limiting their range-of-motion and functional capability such as the ability to contract or relax. Among the more understood of neurological diseases is Muscular Dystrophy—this is an inherited disorder that impairs the functional capability and overall strength of muscles. katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209660560 2017-11-23 10:31:14 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209660560 Metabolic Muscle Diseases This refers to disease wherein the muscles are unable to complete some basic functions such as ensuring proper energy supply to the muscle fibers or the proper removal of toxins released during muscle exertion katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209660819 2017-11-23 10:32:03 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209660819 Inflammatory Muscle Diseases These muscle diseases are characterized by increased inflammation of muscles or the tissues surrounding the muscles. katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209660953 2017-11-23 10:32:31 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209660953 1. Muscular DystrophyIn this genetic disease, a group of muscle diseases cause the damage of muscle fiber. There is no specific cure for it and the symptoms include weakness, immobility and imbalance. The common diseases under this category are Duchenne, Myotonia, Becker, Limb Girdle and Oculopharyngeal.2. Cerebral PalsyCerebral palsy is a very common congenital disorder that affects the posture, balance and motor functions. Muscle tone is lost during pregnancy or during child birth. Physical tasks become difficult because of this disorder.3. Fibrodysplasia Ossificans ProgressivaIn this condition, soft tissue hardens and becomes bone-like permanently. Bone grows between joints and movements get permanently restricted. There is no effective cure available. Only pain management can be done through medication.and anticonvulsants. katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209661251 2017-11-23 10:33:42 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209661251 4. DermatomyositisIn this condition, there is inflammatory myopathy affecting skin and muscle. It is an autoimmune disease harming the connective tissue and weakening the muscles. There is no cure for this condition, but the progression can be controlled by taking corticosteroids and immunosuppressive drugs.5. Compartment SyndromeThe blood vessels, muscles and nerves get compressed in a closed area, which ends up in cutting off the oxygen supply. The result is tissue death which can even lead to paralysis. Immediate treatment is the surgery known as fasciotomy. The pressure on muscles will be released after the surgery. katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209661472 2017-11-23 10:34:25 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209661472 katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209661587 Myasthenia Gravis
In this autoimmune disease, there is muscle weakness and fatigue which are caused by breakdown of the neuromuscular junction. Therefore, the brain does not have control over these muscles. It can cause drooping eyelids, difficulty in breathing or swallowing and loss of facial muscle control. Treatment could be done with medication or surgery.
7. Amyotrophic Lateral Sclerosis
This is a very serious neurodegenerative disease and is also known as Lou Gehrig’s disease. The neurons get destroyed and thus there is loss of control on voluntary muscles. Initial symptoms include difficulty in breathing, speaking and swallowing. Paralysis is also an advanced stage symptom.
8. Mitochondrial Myopathies
The mitochondria are the powerhouse of cells. But in this condition, the mitochondria get damaged. It results in weakness of muscles, deafness, blindness, arrhythmia and heart failure. Sometimes it can cause seizures, dementia, vomiting and droopy eyelids. Nausea, headache and difficulty in breathing are some other symptoms.

The muscle fibers break down into myoglobin which gets excreted in urine. Muscle weakness, pain and stiffness are seen. Treatment is possible when it is detected in early stages by means of IV fluids, dialysis or hemofiltration.PolymyositisPolymyositis is degenerative and inflammatory in nature. It affects the systemic connective tissue causing weakness and muscle atrophy. FibromyalgiaThis is another one the muscular system diseases. Fibromyalgia is a chronic and debilitating muscle disorder. It causes pain, fatigue, tenderness and stiffness of muscles. It is considered a genetic disorder and affects more women than men.MyotoniaIn this condition, the muscles relax slowly after stimulation or contraction. It causes problem when grip is released and when you get up from sitting or sleeping position. Treatment includes medication, physiotherapy katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209661736 2017-11-23 10:35:17 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209661736 katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209663317 2017-11-23 10:42:25 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209663317 Muscle tension refers to the condition in which muscles of the body remain semi-contracted for an extended period. Muscle tension is typically caused by the physiological effects of stress and can lead to episodes of back pain katelin_mcgrath https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209663540 2017-11-23 10:43:21 UTC https://padlet.com/katelin_mcgrath/k59gwcz35fdl/wish/209663540
