What does the atlas allow you to do and where is it found?

This joint enables you to nod "yes". It's C1 of the Cervical Vertebrae.

21

What does the axis allow you to do and where is it found?

It acts as a pivot for the rotation of the atlas (and skull above). Enables you to nod "no". It's C2 of the Cervical Vertebrae.

Body

34

Manubrium

35

These 12 pairs form the walls of the thoracic cage.

Ribs

36

Which are the TRUE ribs? And why are they TRUE ribs?

The first 7 pairs (Ribs 1-7); because they attach directly to the sternum by their "own" costal cartilages.

37

Which are the FALSE ribs? And why are they FALSE ribs?

Ribs 8-12; they attach indirectly to the sternum or entirely lack a sternal attachment.

38

Which ribs are the floating ribs? Why are the "floating" ribs?
