Muscle weakness or myasthenia (my- from Greek μυο meaning "muscle" + -asthenia ἀσθένεια meaning "weakness") is a lack of muscle strength. The causes are many and can be divided into conditions that have either true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy.

Famous quotes containing the word weakness:
“Had Adam tenderly reproved his wife, and endeavored to lead her to repentance instead of sharing in her guilt, I should be much more ready to accord to man that superiority which he claims; but as the facts stand disclosed by the sacred historian, it appears to me that to say the least, there was as much weakness exhibited by Adam as by Eve. They both fell from innocence, and consequently from happiness, but not from equality.”
—Sarah M. Grimke (1792–1873)
