Answer:

Myosin, actin filaments

Explanation:

Muscle contraction is a mechanism in which tension is generated within muscle fibers. It is based on the length and tension of the muscle. This process is neurogenic in nature so motor neurons play an important role in the process of contraction. Myosin and actin filaments play an important role when they interact. There is a formation of cross-bridges that regulates the process of contraction and relaxation.
