ANATOMY

Detailed explanation-1: -Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control. Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control.

Detailed explanation-2: -Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.

Detailed explanation-3: -Voluntary, involuntary, and cardiac muscles are the three types of muscles found in the animal body. The skeletal muscles are considered as the voluntary muscles whereas smooth muscles are considered as the involuntary muscles. Cardiac muscles are found only in the heart.

Detailed explanation-4: -The muscles which move without our will are called involuntary muscles. For example, the cardiac muscle in the heart and the smooth muscles are involuntary muscles. The muscles whose function can be controlled are known as voluntary muscles.

Detailed explanation-5: -The differences are: Cardiac muscles are striated involuntary muscle tissue found in the heart, while smooth muscles are nonstriated involuntary muscles found generally in the viscera. Cardiac muscles are found only in the heart and aorta, while smooth muscles are found in most hollow internal organs and blood vessels.
