Solution
Striated muscles are the skeletal muscles which are also known as voluntary muscles. They are called voluntary muscles because their action is under the control of the somatic nervous system and their movement can be controlled by us (Eg: Bicep muscles), unlike as in the case of involuntary muscles (Eg: cardiac muscles). The muscle fibers of striated muscles are multinucleated and cylindrical. They appear striated due to the presence of alternate light and dark bands when viewed through the microscope.
