Q

If you rotate your head as in indicating a “no” response, most of the movement occurs at this joint:

a. atlanto-occipital (skull-C1)
b. atlanto-axial (C1-C2)
c. C2-C3
d. C3-C4
e. C7-T1

A

b. atlanto-axial (C1-C2)

  • The ATLANTOAXIAL JOINTS permits most of the range of motion associated with rotating the head SIDE TO SIDE as in saying “no”.
  • The ATLANTO-OCCIPITAL JOINTS permit most of the range of motion associated with nodding the head up and down as in saying “yes”.
