What type of muscle tissue is involved in voluntary movements and is striated?

Smooth muscle
Cardiac muscle
Skeletal muscle
Involuntary muscle

The correct answer is: Skeletal muscle

Skeletal muscle is the type of muscle tissue that is responsible for voluntary movements and appears striated. This means that it has a banded appearance under a microscope due to the organization of muscle fibers. Skeletal muscles are attached to bones by tendons and allow for movements like walking, lifting, and other activities that we consciously control. In contrast, smooth muscle is found in the walls of hollow organs like the stomach and blood vessels, and it is not striated and operates involuntarily. Cardiac muscle, found exclusively in the heart, is also striated but functions involuntarily, meaning it is not controlled consciously. Involuntary muscle refers to muscle types, such as both smooth and cardiac, that cannot be controlled at will. Understanding these distinctions is crucial for recognizing how different muscle types function within the body and their specific roles in movement and bodily processes.
