ribs

The image shows a labeled diagram of the 3rd and 1st right ribs, displayed against a light gray background. The 3rd rib is on the left, in a more rounded "C" shape, and the 1st rib is on the right, in a tighter, more curved and steep "C" shape. Labels indicate the "head" or posterior end which articulates with the vertebra, as well as the anterior end, which articulates with the sternal cartilage between ribs 1-10.

A softly lit, eye-level illustration displays two detached ribs set against a plain gray background. Composition-wise, the 3rd right rib is positioned on the left side of the frame, while the 1st right rib resides on the right. Each rib’s key anatomical features are neatly labeled using sans-serif font; labeling highlights articulation points: articulating with the vertebra, and with sternal cartilage within ribs 1-10.
