I'm curious about the mechanism behind biceps contraction. I want to understand how these muscles, which are crucial for arm movements, work when they contract. Specifically, what happens within the muscle fibers during this process?

During contraction, cross-bridges form between the sarcomeres, allowing for the transfer of force.

When this muscle contracts, the forearm is pulled towards the body, resulting in a decrease in the angle of the elbow joint.

They pull on the actin, which is another component of the sarcomeres, generating the force needed to move the forearm.
