The muscular system is the body system responsible for movement. The muscles are attached to bones and make up important organs, like the heart, digestive organs and blood vessels.

Explore antagonistic muscles. Learn the definition of an antagonist muscle and understand how it differs from an agonist muscle. See examples of...

How Muscles Move: Skeletal muscles move through a process called contraction. Muscle fibers, which stretch from one end to another across a muscle, will contract, or shorten. As this …

What happens when a muscle contracts? Learn about the muscle contraction process and the role of the proteins actin and myosin in muscle contraction, as well as the types of muscle …

In this lesson you will find basic background on the muscle system and skeletal system as well as how they work collaboratively to perform the important function of human movement.

Learn about antagonistic muscles in our engaging video. Learn how these muscles work in pairs to create movement and stability in the body, followed by a quiz.

This lesson will explain the role of hydrolysis of ATP in heat production and muscle contraction and explore how skeletal muscle contraction generates heat in support of temperature …

In this lesson you will find basic background on the muscle system and skeletal system as well as how they work collaboratively to perform the important function of human movement.
