Final Answer:
False. The structure described, with two identical lobes located anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum, does not exist.
Step-by-step explanation:
The description does not align with any anatomical structure in the human body. The anterior superior mediastinum primarily houses the thymus, a gland involved in immune function. However, the thymus has a bilobed appearance and is located in the anterior mediastinum, but it is not positioned behind the sternum. Instead, it is more superior in the mediastinum.
Therefore, the statement is false. It is crucial to accurately describe anatomical structures, as misinformation can lead to misunderstanding the body's organization and function.
