Muscle is attached to bone by tendons and other tissue and exerts force by
converting chemical energy into tension and contraction. Muscles move and
make us capable of a variety of actions, but muscle only really contracts and
becomes shorter: they pull but they cannot push. Muscle is made up of millions
of tiny protein filaments which work together to produce motion in the body.
Each of more than 600 muscles is served by nerves which link the muscle to the
brain and spinal cord. Our bodily needs demand that muscles accomplish
different chores, so we are equipped with three types of muscle: cardiac
muscles, found only in the heart, which power the pumping action throughout
life, and “smooth” muscles, which surround or are part of the internal organs.
Both of these muscle types are involuntary and are not under any conscious
control. The third type is muscle we use when we will action; they are what
aches after a ten-mile hike, and are called “striated“ or “skeletal” muscles. These carry out
voluntary movements and make up about 23% of the woman's body weight and
about 40% of a man’s. They’re the body's most abundant tissue and are the
type integrated into our facial tissue.
That’s why facial exercise “works”! |
