Muscles in the Human Body

The human body has approximately 640 muscles.
Muscles are responsible for various types of movement.
Muscles consist of bundles called muscle fibers.
The face has about 42 muscles, responsible for eye movement, facial expressions, and other facial actions.
Muscles give the body shape and mass.

Types of Muscle Tissue

Muscle: A tissue composed of cells or fibers, whose contraction produces body movement. It is also an organ composed of muscle tissue responsible for movement.
Skeletal Muscle: Muscles attached to bones, enabling movement.
Smooth Muscle: Muscles not attached to bones, working automatically (involuntary).
Cardiac Muscle: Involuntary muscles found only in the heart, responsible for rhythmic contractions that pump blood throughout the body.
