ecause flexing muscles look like mice scurrying
beneath the skin,
some scientist long ago dubbed them
, from the Latin
meaning “little
mouse.” Indeed, we tend to think of the rippling muscles of professional boxers or
weight liFers when we hear the word
. But muscle is also the dominant tissue in
the heart and in the walls of other hollow organs. In all its forms, muscle tissue makes up
nearly half the body’s mass.
Muscles are distinguished by their ability to transform chemical energy (ATP) into
directed mechanical energy. In so doing, they become capable of exerting force.
