Document Summary

Any disorder or disease that affects the human muscle system: a. Primary muscle disease the pathology originates with the muscle (internal membranes/metabolic) disorders. Secondary - the pathology originates in other systems. Immune system ms, myositis, muscle rheumatism. Muscle weakness = chronic lack of physical or muscle strength. Upper motor neuron (umn) disease: i. cv-stroke producing weakness of one side of the body. The arm is typically flexed, leg extended, limbs have increased tone. Some movement may be preserved, although the use of the hand is particularly limited: ii. With umn disease the muscle bulk is usually well preserved: iii. Other causes of umn disorders include tumors and spinal cord injury. Lower motor neuron (lmn: spinal cord muscle wasting is prominent shrinkage and eventual death of neurons denervation of muscle. Motor neurons lying in the spinal cord most common amyotrophic lateral sclerosis and lou gehrig. Generally between 50-70yrs and have umn/lmn weakness paralysis progress rapidly and death within 3 years.
