Question

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

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

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

Explanation:

Identify the anatomical orientation

Using the Lung Anatomy knowledge point, we observe two lungs from an anterior view. The lung on the left of the image is the right lung (having three lobes: superior, middle, and inferior, separated by horizontal and oblique fissures). The lung on the right of the image is the left lung (having two lobes: superior and inferior, separated by an oblique fissure).

Locate label A on the diagram

Label A points directly to the broad, concave lower boundary of both the right and left lungs. This inferior surface rests directly on the dome of the diaphragm.

Match label A to its anatomical term

In pulmonary anatomy, the broad, concave inferior surface of the lung is called the base. The pointed superior tip of the lung is the apex (labeled G). Therefore, label A corresponds to the base.

Answer:

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