provide heat. There are 3 types of muscles smooth which are a part of blood
vessels, ducts, digestive and reproductive systems. Cardiac is the muscle that
makes up the heart. Skeletal muscles are the muscles that move the skeleton.

There are many different
joints such as the fixed joint where bones are bound together meaning they have
little movement. Another joint is the ball and socket joint this joint allows
movement in all directions for example the shoulder. The ellipsoidal joint
allows movement in nearly all directions with minimum rotation the wrist is an
example of this joint. The hinge joint this joint bends or straightens for
example finger joints and the knee. Semi movable joint this joint joins the pelvis.
