Which type of muscles are consciously controlled and attach to bones?

Striated muscles, often referred to as skeletal muscles, are the type of muscles that are consciously controlled and attach to bones. These muscles are characterized by their long, cylindrical fibers that have a striped appearance under a microscope due to the arrangement of actin and myosin filaments. This striation is a visual hallmark of skeletal muscle tissue and distinguishes it from other types of muscle.

Skeletal muscles enable voluntary movements, allowing individuals to perform actions such as walking, lifting, and other physical activities. The ability to consciously control these muscles is a key feature, as they are innervated by the somatic nervous system, which is responsible for voluntary movements.

The other options represent different types of muscle tissue. Smooth muscles are involuntary and found in the walls of internal organs; cardiac muscles, also involuntary, make up the heart; and nonstriated muscles generally refer to smooth muscle, lacking the striations seen in skeletal muscle. Thus, the identification of striated muscles as those that are consciously controlled and attach to bones is accurate and reflects their role in voluntary movement.
