Question

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

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

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

Explanation:

Identify the anatomical structures

Using the Lung Anatomy and Pulmonary Lobes knowledge points

• The image displays the anterior surface of both human lungs (right lung on the left, left lung on the right).
• Label A points to the base of the lungs.
• Label G points to the apex of the lungs.
• Label F points to the superior lobe of both lungs.

Analyze the fissures and lobes

Using the Pulmonary Fissures knowledge point

• The right lung (left side of image) has three lobes separated by two fissures:
• F: Superior lobe
• D: Horizontal fissure
• C: Middle lobe
• B: Oblique fissure
• E: Inferior lobe
• The left lung (right side of image) has two lobes separated by one fissure:
• F: Superior lobe
• D: Oblique fissure
• B: Inferior lobe

Determine the identity of label B

Using the Pulmonary Lobes knowledge point

• On the right lung, B points to the oblique fissure (separating the middle/superior lobes from the inferior lobe).
• On the left lung, B points to the inferior lobe (the region below the oblique fissure D).
• Looking at the multiple-choice options, "inferior lobe" is a direct match for the region labeled B on the left lung.

Match with the correct option

Using the Lung Anatomy knowledge point

• Label B on the left lung clearly represents the inferior lobe.

Answer:

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