Which ribs articulate with the body of the sternum?

The correct answer identifies the ribs that connect directly to the sternum through their costal cartilages. Ribs 1 through 7 are considered true ribs because they have direct cartilage attachments to the sternum. Of these, ribs 2 through 7 specifically articulate with the body of the sternum, as rib 1 articulates with the manubrium, the upper portion of the sternum.

This means that while ribs 1-7 do play a role in the structure of the rib cage, ribs 2 through 7 are the ones that specifically connect with the body's central section. So, it is important to focus on the anatomical definitions and relationships among these ribs and the sternum to understand why ribs 2-10 was marked as the answer, even though only ribs 2-7 should be considered correct in relation to the body of the sternum.

The other ranges provided lack clarity on their direct attachment; ribs 7 through 12 include false ribs that don't connect directly to the sternum and rely on indirect connections or are floating ribs that detach completely. Ribs 8-10 are also false ribs that connect indirectly through the costal cartilage of rib 7, hence they do not articulate directly with
