Multiple Choice

Which anatomical feature can help you distinguish the anterior (front) surface of the heart from the posterior (back) surface?

The presence of the interventricular sulcus and the position of the right ventricle

The attachment of the aorta to the left ventricle

The presence of the coronary sinus

The location of the pulmonary veins entering the left atrium

Verified step by step guidance

Step 1: Understand the anatomical orientation of the heart. The anterior (front) surface of the heart is primarily formed by the right ventricle, while the posterior (back) surface is dominated by the left atrium and structures such as the pulmonary veins.

Step 2: Identify the interventricular sulcus. This groove runs along the anterior surface of the heart and separates the right and left ventricles. It is a key feature that helps distinguish the anterior surface.

Step 3: Note the position of the right ventricle. The right ventricle is prominently located on the anterior surface of the heart, making it a distinguishing feature when compared to the posterior surface.

Step 4: Consider the attachment of the aorta to the left ventricle. While this is an important anatomical feature, it is not specific to distinguishing the anterior from the posterior surface.

Step 5: Evaluate the presence of the coronary sinus and pulmonary veins. The coronary sinus is located on the posterior surface, and the pulmonary veins enter the left atrium on the posterior side, helping to identify the back of the heart.
