Final answer:
The middle cardiac vein lies alongside the posterior interventricular artery, not the anterior interventricular artery, making the statement false.
Step-by-step explanation:
The statement that the middle cardiac vein lies alongside the anterior interventricular artery is false. The middle cardiac vein parallels and drains the areas supplied by the posterior interventricular artery, and it drains into the great cardiac vein. On the other hand, it is the great cardiac vein that follows the interventricular sulcus on the anterior surface of the heart and parallels the anterior interventricular artery.
