The unique structures of the cervical vertebrae include vertebral body hooks, hook vertebral joints, transverse foramina, atlantoaxial vertebrae, pivot vertebrae and vertebral ramus. 1. Vertebral body hooks: the cervical vertebrae are small, elliptical in cross-section, with the articular surfaces of the upper and lower articular eminences almost horizontal, and the lateral margins of the upper part of the 3rd to 7th cervical vertebrae protruding upward, known as the vertebral body hooks. 2. Hooked vertebral joints: the hooks of the vertebral body and the upper vertebral body below the lips on both sides of the joint, forming the hooked vertebral joints. 3. Transverse foramen: There is a hole in the transverse process, called the transverse foramen, through which the vertebral artery and vertebral vein pass. 4. atlas: the first cervical vertebra, ring-shaped, without vertebrae, spinous processes and articular processes, consisting of anterior arch, posterior arch and lateral blocks. 5. Pivot vertebra: the second cervical vertebra, the vertebral body extends upward to the dentition, and is associated with the atlantoaxial dentition. 6. Lumbar vertebra: the seventh cervical vertebra, the spinous process is particularly long, the end is not bifurcated, and it is easy to reach in vivo, and is often used as a marker for counting the number of vertebrae in a sequence. The above anatomical knowledge is for reference only, if you have cervical spine discomfort, it is recommended to go to the hospital in time.
