Verified step by step guidance

Understand the anatomy of the lung: The lung has distinct regions, including the apex, base, medial surface, and lateral surface. Each region has specific anatomical characteristics and relationships with surrounding structures.

Define the term 'apex': In anatomy, the apex refers to the pointed or narrow end of an organ. For the lungs, this is the superior portion that extends upward toward the clavicle.

Compare the options provided: Analyze each option to determine which one matches the definition of the apex. For example, the broad inferior surface resting on the diaphragm refers to the base of the lung, not the apex.

Focus on the superior pointed portion near the clavicle: This description aligns with the anatomical definition of the apex of the lung, as it is the uppermost part of the lung located near the clavicle.

Eliminate incorrect options: The medial surface facing the heart refers to the side of the lung adjacent to the heart, and the lateral surface adjacent to the ribs refers to the outer side of the lung. Neither of these matches the definition of the apex.
