How do you tell the difference between a left and right rib?
Because the right rib cage is farther from the film, the projection of the right ribs on a lateral radiograph will fan out and diverge in a vertical direction to a greater degree than that of the left ribs. Thus, the right side can be distinguished from the left by the vertical displacement of the paired ribs.
What does an elevated first rib feel like?

To test, palpate bilaterally by gently springing the rib inferiorly and observe for motion dysfunction.
What is the name of first rib?

Anterior to the scalene tubercle is another groove for the subclavian vein. There is no costal groove on its inferior surface.
