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

The three types of muscle tissue in the body are skeletal, cardiac, and smooth. This classification is based on the muscle tissue's structure and function.

Skeletal muscle is striated and under voluntary control, enabling movement of the skeleton and bodily posture. It is attached to bones and facilitates movement through contraction and relaxation in response to conscious thought.

Cardiac muscle, found exclusively in the heart, is responsible for pumping blood throughout the body. It is striated like skeletal muscle but operates involuntarily, meaning it functions without conscious effort. Cardiac muscle can also contract rhythmically and is equipped with intercalated discs that allow for coordinated contractions.

Smooth muscle is non-striated and also operates involuntarily. It is located in the walls of hollow organs such as the intestines, blood vessels, and bladder. Smooth muscle contractions help in processes like digestion, circulation, and urination.

The other options either mix muscle with non-muscle tissues or incorrectly categorize muscle types, which is why they do not accurately represent the three types of muscle tissue.
