.Skeletal muscles are known as voluntary muscles because their activities are under the voluntary control of the nervous system.The striated appearance of myofibrils is due to the distribution pattern of two important proteins - Actin and Myosin. The light bands contain actin and the dark bands contain myosin.The light bands in a myofibril contain actin and is called I-band or Isotropic bandThe actin filaments are thinner as compared to the myosin filaments. Hence, they are commonly referred to as thin filaments and thick filaments, respectively.Both the actin and myosin filaments are arranged as rod-like structures, parallel to each other and also to the longitudinal axis of the myofibrils.
