@OMM-Support I also think this might cause unnecessary confusion but could be an okay add to the extra.
I’m ok with adding it, it seems minimal enough to where it wouldn’t be too much and I think people would understand it.
Sorry for the confusion, but I wanted to emphasize that the OA joint (flexion/extension) is the motion of C0 itself on C1.
Like how the C1/C2 joint is the rotation of C1 on C2. So you WOULD NOT say that the C1/C2 joint is rotated Right/Left, but instead say C1 is rotated Right/Left.
It is a bit confusing when we learn the joints instead of the individual vertebrae themselves because a lot of the questions refer to the vertebrae. For example, a question about rotation will ask if it is C1 or C2 that is rotated when both are present in the AA joint.
