If a motor neuron is damaged, it can cause the muscle it innervates to atrophy because of lack of stimulation.…
lack of oxygen in the bloodstream which would cause muscle cramps and lactic acid buildup or multiple sclerosis which has all of the symptoms expressed.…
This afflictive condition may occur at very inopportune moments, for instance while playing tennis you may lose a point due to the sudden pain. Besides, it may also occur while you are resting, walking or sleeping, and causes unbearable pain for few…
Muscle Fatigue is when a muscle gets tired and does not have the ability to generate a force. It can occur because of too much vigorous exercise (aerobic respiration). Lactic acid is produced when there is a high demand for energy, when there is too much the body gets tiresome and weakens the muscle. (3)You can get rid of lactic acid by doing the right amount of exercise that your body needs and doing it periodically.…
When a muscle or group of muscles involuntarily contracts this is called a muscle cramp. A muscle contracting causes it to get smaller and tighter, causing pain and temporary unavailability of the muscle or muscles. There are many causes behind muscle cramps but the most frequent are muscle fatigue, dehydration, lack of stretching, poor circulation, and magnesium or calcium insufficiency. When a muscle is…
Muscle fatigue, or physical fatigue, is the decline in ability of a muscle to generate force. It can be a result of strenuous exercise but unusual fatigue may be caused by interference with the different stages of muscle contraction. There are two main causes of muscle fatigue, nervous fatigue and metabolic fatigue.…
Transition Statement: Think back to when you woke up this morning. Did you experience any muscle pain? Was your body stiff? Did you notice any joint pain? This could be because you slept wrong last night or maybe you need a new mattress. Or it might be Fibromyalgia.…
In a normal muscle contraction, the motor neuron (effector) releases Acetylcholine (Ach), a neurotransmitter, at the neuromuscular junction. Then the Ach binds with Nicotinic Ach receptor (AchR) on the membrane of the muscle and causes a chain reaction which contracts the muscle. MG is caused by autoantibodies which mean that the autoantibodies are blocking out the Ach. This causes the autoantibodies to bind with nicotinic AchR. This means the Ach that were released by the motor neurons were not able to bind with the AchR. The result is that no signal could be sent out to contract the muscle, and that causes fatigue in the…
Muscular Dystrophy,the progressive loss and weakness of muscle,is a muscular disorder first described in the 1860’s by a french neurologist .The term Muscular Dystrophy encompasses any type of dystrophy of muscles,about nine different types.The most common type is Duchenne Muscular Dystrophy which makes up approximately half of muscular dystrophy cases. Muscular Dystrophy is most present in boys,but girls may also carry the gene,although they usually show no symptoms.In 2007, it was revealed that 1 in 3500 males aged 5 to 25 are diagnosed with muscular dystrophy with symptoms emerging,on average, at two and a half years of age.…
The symptoms of myositis can be muscle pain and weakness in body. When your body is in pain due to myositis it’s called (Myalgia’s) and this may or may not appear during the experience…
Muscular dystrophy is a group of inherited disorders that involve muscle weakness and loss of muscle tissue, which get worse over time.…
imbalances or tissue damage, hence the loss of the ability to contract, or muscle fatigue.…
Somatoform Pain disorder is when a person has several complaints of pain for which they have sought medical evaluation which in turn the healthcare cannot find any cause or reason behind the pain. The pain is so severe that it interferes with a person’s everyday life. This pain is thought to be the cause of psychological problems because there is no physical cause shown. People with somatoform pain disorder are not malingering (faking) their symptoms, they are very real to them.…
Neurofibromatosis is an autosomal dominant genetic disorder that causes tumors to form in and on the brain, spinal cord, and nerves. This disorder is diagnosed by a number of tests, such as physical examinations, CT scans, MRI’s, and genetic testing. Researching medical and family histories can also be helpful. Neurofibromatosis cannot be cured; however, treatments may help. Treatments can include chemotherapy, radiation therapy, or surgeries, such as laminectomies and spinal fusions. Some people might not even need more than careful observation. With this disease, there are a few symptoms, which depends on the type of neurofibromatosis you are diagnosed with.…
muscle wasting and weakness. It can detect abnormalities such as chronic denervation or fasciculations in clinically normal muscle. It can, by determining the distribution of neurogenic abnormalities, differentiate focal nerve, plexus, or radicular pathology; and it can provide supportive evidence of the pathophysiology of peripheral neuropathy, either axonal degeneration or demyelination. EMG is an obligatory investigation in motor neurone disease to demonstrate the widespread denervation and fasciculation required for secure diagnosis.…
