Verified step by step guidance1
Step 1: Understand the anatomical directional terms involved. 'Anterior' means toward the front of the body, 'posterior' means toward the back, 'lateral' means away from the midline, and 'inferior' means below another structure.
Step 2: Identify the location of the sternum. The sternum, or breastbone, is a flat bone located in the center of the chest at the front of the thoracic cage.
Step 3: Identify the location of the heart. The heart is located in the thoracic cavity, slightly left of the midline, and lies posterior to the sternum.
Step 4: Compare the positions of the sternum and the heart using the directional terms. Since the sternum is in front of the heart, it is anterior to the heart.
Step 5: Conclude that the correct anatomical directional relationship is that the sternum is anterior to the heart, confirming the statement 'Yes; the sternum is anterior to the heart.'
