With the cervical spine held in full flexion, rotation is measured to each side and found to be markedly reduced to the right. This finding MOST implicates:
1The cervicothoracic junction where the lower cervical meets the upper thoracic spine
2The temporomandibular joint on the side of the restricted rotational movement noted
3The upper cervical segment between the first and second vertebrae✓ 정답
4The mid cervical segments between the fourth and fifth cervical vertebrae bilaterally
