What term is used to describe muscles that have a banded appearance and are under voluntary control?

The correct term used to describe muscles that have a banded appearance and are under voluntary control is "striated muscles." This type of muscle is characterized by its striped or banded look, which is due to the organized structure of the muscle fibers that contain alternating dark and light bands. These striations are created by the arrangement of actin and myosin filaments within the muscle cells, allowing for the contraction needed for voluntary movements. Striated muscles are found primarily in skeletal muscles, which work to move bones and are consciously controlled by the nervous system.

In contrast, smooth muscles are not striated and operate involuntarily, meaning they function without conscious control. Cardiac muscles, while striated, are also primarily under involuntary control, found only in the heart. Nonstriated muscles, another term referring to smooth muscles, further emphasizes the absence of the banded pattern and their involuntary characteristics. Thus, the distinct features of striated muscles in terms of appearance and control clearly identify them as the correct answer.
