Muscle contraction occurs when actin connects with myosin.

Muscle contraction occurs thanks to an action potential, which transmits a stimulus to the interior of the muscles.

  • For fiber tension to occur, the myosin head must bind with actin, slip, release, and then connect with another actin.

  • This electrical signal allows the actin and myosin proteins to move, thereby generating contraction of the muscles.

Therefore, we can conclude that myosin is a protein found in muscle fibers in order to bind to actin protein and cause muscle contraction.
