Etymology

Noun

from Latin musculus "muscle, little mouse," from mus "mouse"

Word Origin

People today are perhaps unlikely to think of their muscles as resembling mice. The ancient Romans, however, saw a likeness, especially in the major muscles of the arms and legs. For that reason the Latin word musculus, which originally meant "little mouse," came to be used to mean "muscle."
