Muscles
Almost half the body's weight is muscle. Muscles are the part of our body that allow us to move. They are made up of special tissues that can contract, or shorten, when they receive a signal from the brain. The muscles are attached to bones by stretchy tissue called tendons. When the muscles contract, they pull on the tendons which pull on the bones and cause our limbs to move.
There are more than 640 muscles, and they hardly ever work alone. Muscles can get shorter and pull, but they cannot push. So most muscles are arranged in opposing teams. One team pulls the body part one way, then the other team pulls it back again. As each team pulls, the other team relaxes and gets stretched. Muscles band together to form muscle groups which work
together.
The muscular system consist of three different types of muscle tissues : skeletal, cardiac, smooth. Each of these different tissues has the ability to contract, which then allows body movements and functions.
Muscles which we can control by ourselves are called the voluntary muscles; the ones we
can't control are the involuntary muscles. The heart, or the cardiac muscle, is an example of involuntary muscle.
Cardiac Muscle: the cardiac muscles is the muscle of the brain itself. The cardiac muscle is the tissue that makes up the wall of the heart called the mydocardium. Also like the skeletal muscles, the cardiac muscle is striated and contracts through the sliding filament method. However it is different from other types of muscles because it forms branching fibers. Unlike the skeletal muscles, the cardiac muscle is attached together instead of been attach to a bone.
Skeletal Muscle: the skeletal muscle makes up about 40 % of an adults body weight. It has stripe-like markings, or striations. The skeletal muscles is composed of long muscle fibers. Each of these muscles fiber is a cell which contains several nuclei. The nervous system controls the contraction of the muscle. Many of the skeletal muscle contractions are automatic. However we still can control the action of the skeletal muscle. And it is because of this reason that the skeletal muscle is also called voluntary muscle.
Smooth Muscle: much of our internal organs is made up of smooth muscles. They are found in the urinary bladder, gallbladder, arteries, and veins. Also the digestive tract is made up of smooth muscle as well. The smooth muscles are controlled by the nervous system and hormones. We cannot consciously control the smooth muscle that is why they are often called involuntary
muscles.

Visit the Innerbody
website for a complete and detailed clickable image of the human muscles, or
visit the Hosford
Muscle Tables for an alphabetic list of all human muscles. Bartleby.com edition of Gray’s Anatomy of the Human Body
contains detailed information (and images) on arteries, muscles, bones etc.
Definitely worth a visit!
