ANATOMY

Detailed explanation-1: -Skeletal muscle fibers occur in muscles which are attached to the skeleton. They are striated in appearance and are under voluntary control.

Detailed explanation-2: -Which muscles are voluntary? Voluntary muscles are skeletal muscles that attach to bones and can be consciously activated to control movement. Common voluntary skeletal muscles include the biceps, triceps, lats, abdominals, glutes, quadriceps, and hamstrings.

Detailed explanation-3: -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.

Detailed explanation-4: -The body possesses two types of striated muscle, cardiac and skeletal.
