Question

given the following photo of a human cadavers anterior lung surface:

match the component labeled with a(n) \g\ to its associated name from the choices below.

apex
base
inferior lobe
middle lobe
horizontal fissure
oblique fissure
superior lobe

Explanation:

Identify the anatomical orientation

The image shows the anterior surface of a pair of human lungs from a cadaver. The lung on the left side of the image has three lobes (superior, middle, and inferior) separated by two fissures (horizontal and oblique), which identifies it as the right lung. The lung on the right side of the image has two lobes separated by a single oblique fissure, identifying it as the left lung.

Analyze the label "G"

The label "G" points to the superior-most, tapered tip of both the right and left lungs. This pointed superior region of each lung projects superiorly above the level of the first rib into the root of the neck.

Match label "G" to its anatomical term

In pulmonary anatomy, the superior tip of the lung is called the apex. The broad, concave inferior surface that rests on the diaphragm is called the base (labeled as "A"). Therefore, the component labeled "G" corresponds to the apex.

Answer:

• apex (Correct answer)
• base
• inferior lobe
• middle lobe
• horizontal fissure
• oblique fissure
• superior lobe
