Human muscle system | Functions, Diagram, & Facts | Britannica
The human muscle system comprises the muscles that work with the skeletal system for voluntary movement, posture, and balance. It is broadly categorized into three types: striated muscle (skeletal muscle), smooth muscle, and cardiac muscle.

Muscles of the Body: Types, Groups, Anatomy & Functions
Smooth muscle tissue lines some of your organs, but most organs are also made of other types of tissue, too. Providers sometimes refer to the muscular system as one anatomical group that includes all your muscles.

Interactive Guide to the Muscular System | Innerbody
There are three types of muscle tissue: Visceral, cardiac, and skeletal. Visceral muscle is found inside of organs like the stomach, intestines, and blood vessels. The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ.

Muscular system - Wikipedia
There are three distinct types of muscle: skeletal muscle, cardiac or heart muscle, and smooth (non-striated) muscle. Muscles provide strength, balance, posture, movement, and heat for the body to keep warm.

These muscle actions are often paired, like flexion and extension or abduction and adduction. Below the common terms are listed and defined, with animations to help you picture the muscles and joints in motion. Flexion and extension are usually movements forward and backward from the body, such as nodding the head.

Muscle | Systems, Types, Tissue, & Facts | Britannica
Muscle, contractile tissue found in animals, the function of which is to produce motion. Muscle cells fuel their action by converting chemical energy in the form of adenosine triphosphate (ATP), which is derived from the metabolism of food, into mechanical energy.

Definition, Types, Structure, and Functions of Muscles
Muscle Definition: A muscle is a soft tissue made up of cells that contract to produce movement or locomotion in animals. The human body has over 600 muscles that makeup about 40–50% of the body's weight.
