A female patient unable to walk due to a muscular disease likely has an issue with which type of muscle?

The female patient’s inability to walk due to a muscular disease is indicative of an issue with skeletal muscle. Skeletal muscles are the ones responsible for voluntary movements of the body, such as walking, running, and performing other activities. They are attached to the bones and enable movement through contraction and relaxation.

In muscular diseases that affect skeletal muscle, such as muscular dystrophy or myopathy, the function of these muscles can be severely compromised, leading to weakness or paralysis that directly impacts a person's ability to move.

Smooth muscle and cardiac muscle, on the other hand, are not involved in voluntary movements. Smooth muscle is found in the walls of hollow organs and is responsible for involuntary actions such as digestion and regulation of blood flow. Cardiac muscle makes up the heart and also functions involuntarily to pump blood. Involuntary muscle refers to both smooth and cardiac muscle, which operate without conscious control.

Thus, the correct answer highlights the role of skeletal muscle in voluntary movement, making it the type of muscle impacted in this patient's condition.
