Question

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

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

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

Explanation:

Identify the anatomical structures of the lungs

Using the Lung Anatomy knowledge point

• The image shows the anterior surface of the right lung (left side of image) and left lung (right side of image).
• Label G points to the apex of both lungs.
• Label A points to the base of both lungs.

Analyze the right lung fissures and lobes

Using the Pulmonary Lobes and Pulmonary Fissures knowledge points

• The right lung has three lobes: superior (F), middle (B), and inferior (C).
• These lobes are separated by two fissures: the horizontal fissure (E) and the oblique fissure (D).
• Specifically, the horizontal fissure (E) separates the superior lobe (F) from the middle lobe (B).
• The oblique fissure (D) separates the inferior lobe (C) from the middle (B) and superior (F) lobes.

Match label E to its anatomical name

Using the Pulmonary Fissures knowledge point

• Label E points directly to the horizontal fissure on the right lung.
• Therefore, the correct choice is "horizontal fissure".

Answer:

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