Luschka's joints

In anatomy, Luschka's joints (also called uncovertebral joints, neurocentral joints) are formed between uncinate processes above, and the uncus below. They are located in the cervical region of the vertebral column between C3 and C7. Two lips project upward from the superior surface of the vertebral body below, and one projects downward from the inferior surface of vertebral body above. They allow for flexion and extension and limit lateral flexion in the cervical spine.
