Myanmar: an old name for a part of Burma and a word for the country in native speech, officially chosen by military rulers of Burma in 1989. Reasons given include casting off a relic of colonialism, or downplaying of the connection to the Burman ethnic majority.
It should be pointed out that this renaming has virtually no impact on Burmese citizens speaking in Burmese, who continue to refer to both Myanma as well as Bama (this not unlike formal reference in the English language to 'The Netherlands' while informally using 'Holland').

myasthenia (n.): "muscular weakness," 1856, medical Latin; see myo- + asthenia.
