What type of muscle is responsible for voluntary movement of the body?

Skeletal muscle is the type of muscle responsible for voluntary movement of the body. This muscle tissue is attached to the bones and operates under conscious control, allowing you to perform various movements such as walking, running, and lifting. Each skeletal muscle fiber is striated, which is a characteristic that helps differentiate it from other types of muscle tissues.

In contrast, cardiac muscle is found only in the heart and is involuntarily controlled, meaning it functions without conscious effort. Smooth muscle, which is also involuntary, lines organs and structures such as the intestines and blood vessels, facilitating processes like digestion and blood flow without conscious control. The term "involuntary muscle" encompasses both cardiac and smooth muscle, emphasizing their autonomous function. Thus, skeletal muscle is the distinct type responsible for voluntary movements, making it the correct answer.
