According to the research, muscle fibers can produce contraction and are made of myofibrils.
What are the muscle fibers?
They are the fibers that are located inside the muscle, which in turn are composed of sarcolemma, mitochondria, myofibrils, nucleus and sarcoplasmic reticulum.
The myofibrils are responsible for giving it the elastic characteristic and are made up of actin and myosin that fulfill the function of generating the contraction process.
Therefore, we can conclude that according to the research, muscle fibers can produce contraction and are made of myofibrils.
