Muscle are made up of muscle functions called____ ____. Its two words... I was thinking myosin and actin , however, not sure if i AM CORRECT.

Yes, you are correct! Muscle fibers are made up of two main proteins: myosin and actin. These proteins work together to enable your muscles to contract and generate force. Myosin is a thick protein filament, while actin is a thin protein filament. The interaction between myosin and actin allows muscles to shorten or lengthen, resulting in movement.
