Which view demonstrates the cervical zygapophyseal joints?

How is the patient positioned to demonstrate the left zygapophyseal joints of the cervical vertebrae?
The correct answer is (C). The posterior oblique positions (LPO and RPO) of the lumbar vertebrae demonstrate the zygapophyseal joints closer to the IR. The left zygapophyseal joints are demonstrated in the LPO position, whereas the right zygapophyseal joints are demonstrated in the RPO position.
Which position or projection of the cervical spine will best demonstrate the Zygapophyseal joint spaces between C1 and C2?

Which position or projection of the cervical spine will best demonstrate the Zygapophyseal joint spaces between C1 and C2 quizlet?
The PA projection (Judd method) is intended to demonstrate the zygapophyseal joint between C1 and C2. The posterior cervical oblique projections demonstrate the intervertebral foramina and pedicles on the side closest to the image receptor.
