What are the three types of muscle found in the body?

The three types of muscle found in the body are skeletal, smooth, and cardiac. Skeletal muscle is responsible for voluntary movements and is attached to bones, allowing for movement of the skeleton. It is typically striated in appearance because of its organized structure. Smooth muscle, on the other hand, is involuntary and found in walls of hollow organs like the intestines and blood vessels, helping to regulate functions such as digestion and blood flow. Cardiac muscle is also involuntary and striated, specifically found in the heart, and it plays a crucial role in pumping blood throughout the body.

This classification considers both the function and the structure of the muscles, which is essential for understanding how they work within the human body. The terminology used in the other choices—like "striated"—can be accurate but doesn't completely encompass the way we classify muscle types, particularly when it comes to distinct categories like cardiac muscle. Elastic is not recognized as a type of muscle; hence it is not a valid classification in the context of human muscle types.
