Learn about the major skeletal muscle functions. Deepen your knowledge of the structure of skeletal muscle, the characteristics of skeletal muscle, and more.

Learn about the organization of skeletal muscle tissue. Discover the connective tissue layers associated with the skeletal muscles and their functions.

In this lesson, learn about the three types of muscle tissue. Explore the difference between skeletal and smooth muscle and see a cardiac muscle...

Understand what proprioceptors in muscles are. Learn more about muscle spindle function and Golgi tendon organs. Discover different types of...

Learn about the length-tension and force-length relationship and why they are important to skeletal muscle. Discover examples of the length-tension curve.

All skeletal muscle fibers are striated with a regular arrangement of actin (thin) and myosin (thick) filaments. Skeletal muscle fibers are further defined based on whether they are slow-twitch ...

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 contraction and ...

The cross-bridge muscle contraction cycle is recognized in all types of muscles, such as cardiac, smooth, and skeletal muscles. This means that all muscle types contract by cross-bridge cycling.

Learn what excitation-contraction coupling is. Discover key actors in muscle contraction and identify the steps of the muscle contraction and relaxation process.

Learn about multinucleated muscle cells, skeletal muscle nuclei, and multiple nuclei in fungus. Find out how many nuclei are in cardiac muscles and skeletal muscles.
