Answer:

To answer your question, the filaments that make up skeletal muscles are called actin and myosin filaments. The actin filaments are thin and the myosin filaments are thick, and they slide past each other to cause the muscle to contract. The contractile units of skeletal muscles are called sarcomeres, which are made up of these actin and myosin filaments.
