Question 37

occiput-atlas side bend RIGHT

Answer 37

occiput translates LEFT
(but shape of condyle
prevents pure
translation such that
with right SB, the right
OA goes into some ext
[ie, right condyle moves
into an anterior
position] and the left
OA into some flexion
[ie, the left condyle
moves posteriorly].
 Also accompanied by
some rotation to LEFT
of C1 on C2 and
accompanied by right
rotation of C2 on C3
