The Muscular System
Your muscular system is responsible for the movement in your body.
You have three main types of muscle in your body – striated, visceral and cardiac.
Striated Muscles
Striated muscles are the muscles attached
to your skeletal system and there are
around 650 named muscles that fall into this
category, which make up almost half of your
body weight! They are the only voluntary
muscles in your body, which means they
are controlled consciously. Every action you
choose to perform, such as walking, running,
speaking, sitting is controlled by these
striated muscles. The fibres in striated muscle
are very strong and they contract rapidly.
The purpose of these muscles is to contract in
order to move parts of the body closer to
the bone that the muscle attaches to.
Most are attached to two bones by a tendon,

across a joint, and the muscle brings these
two bones closer - think of your arms or legs
bending. A tendon is a tough band of dense
connective tissue which attaches the muscle
to the bone firmly.
