| umls-concept:C0026896 | skos:definition | MSH: A disorder of neuromuscular transmission characterized by weakness of cranial and skeletal muscles. Autoantibodies directed against acetylcholine receptors damage the motor endplate portion of the NEUROMUSCULAR JUNCTION, impairing the transmission of impulses to skeletal muscles. Clinical manifestations may include diplopia, ptosis, and weakness of facial, bulbar, respiratory, and proximal limb muscles. The disease may remain limited to the ocular muscles. THYMOMA is commonly associated with this condition. (Adams et al., Principles of Neurology, 6th ed, p1459),CSP: disease characterized by progressive weakness and exhaustibility of voluntary muscles without atrophy or sensory disturbance and caused by an autoimmune attack on acetylcholine receptors at the neuromuscular junction.,NCI: A chronic autoimmune neuromuscular disorder characterized by skeletal muscle weakness. It is caused by the blockage of the acetylcholine receptors at the neuromuscular junction.,MEDLINEPLUS: <p>Myasthenia gravis is disease | lld:umls |
