Begin by understanding the classification of muscle tissues. There are three main types: skeletal, cardiac, and smooth muscle.
Skeletal muscle is voluntary, meaning it is under conscious control. It is responsible for movements of the skeleton and is striated in appearance.
Cardiac muscle is found in the heart and is classified as involuntary. It contracts without conscious control to pump blood throughout the body. It is also striated.
Smooth muscle is also involuntary and is found in the walls of hollow organs such as the intestines, blood vessels, and bladder. It is not striated.
Striated muscle refers to the appearance of muscle fibers under a microscope, which can be seen in both skeletal and cardiac muscles. However, the term 'striated muscle' does not specify whether it is voluntary or involuntary.
