A sarcomere is a basic unit of function within muscle tissue. The contract with the use of thick and thin filaments in order to allow muscle to shorten or contract. What does myofibril mean?

Learn about sarcomeres in our informative video lesson. Explore their structure, parts, and function in muscle contraction, then take a quiz to review.

The sarcomere is the unit of the muscle fiber responsible for contraction and gives skeletal muscle its striated appearance. The two proteins known... See full answer below.
