What type of muscle tissue is known as involuntary muscle and is found in internal organs?

• A. Cardiac muscle
• B. Skeletal muscle
• C. Visceral muscle
• D. Striated muscle

Answer: (C)

Visceral muscle, also known as smooth muscle, is a type of involuntary muscle tissue that lines the walls of internal organs such as the digestive tract, blood vessels, and bladder. This muscle type operates without conscious control, allowing for automatic movements such as peristalsis in the intestines or the contraction and relaxation of blood vessels. While cardiac muscle is also involuntary, it is specifically found only in the heart. Skeletal muscle, in contrast, is voluntary and is attached to bones, allowing for deliberate movements. Striated muscle refers to the appearance of skeletal and cardiac muscles under a microscope, featuring a banded or striated look, but does not denote involuntary action. Thus, visceral muscle is the best choice for describing involuntary muscle tissue located in internal organs.
