The muscular system. The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.

The muscular system in vertebrates consists of three different types of muscles: cardiac, skeletal and smooth.
