Which of the following statements about cardiac muscle is correct?

Eliminate incorrect options: Cardiac muscle cannot be classified as skeletal muscle because skeletal muscle is voluntary. It also cannot be classified as smooth muscle because smooth muscle lacks striations. Additionally, cardiac muscle is found in the heart, so the statement that it is not found in the heart is incorrect.

Identify the correct classification: Cardiac muscle is striated, like skeletal muscle, but it is involuntary, like smooth muscle. This combination makes it unique and distinct from the other muscle types.
