Feedback: Myasthenia gravis is characterized by a weakness of muscles, especially in the face and throat, caused by a lower neuron lesion at the myoneural junction. It isn't a genetic disorder. Combined upper and lower neuron lesions generally occur as a result of spinal injuries. A lesion involving cranial nerves and their axons in the spinal cord causes decreased conduction of impulses at an upper motor neuron.
