The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body. The muscular system in vertebrates is controlled through the nervous system, although some muscles (such as the cardiac muscle) can be completely autonomous.

Famous quotes containing the words muscular and/or system:
““In my youth,” said his father, “I took to the law,
And argued each case with my wife;
And the muscular strength, which it gave to my jaw,
Has lasted the rest of my life.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“Such is the remorseless progression of human society, shedding lives and souls as it goes on its way. It is an ocean into which men sink who have been cast out by the law and consigned, with help most cruelly withheld, to moral death. The sea is the pitiless social darkness into which the penal system casts those it has condemned, an unfathomable waste of misery. The human soul, lost in those depths, may become a corpse. Who shall revive it?”
—Victor Hugo (1802–1885)
