First cervical vertebra (atlas)

Second cervical vertebra (pivot)

Seventh cervical vertebra (vertebrae)

There is a transverse foramen at the root of the transverse process, through which the vertebral artery and vertebral vein pass

There are semicircular costal recesses on the upper and lower edges of the posterolateral side of the vertebral body, and there is a transverse costal recess in front of the end of the transverse process.

The spinous processes are long and slender, extending posteriorly and downwardly, arranged in an imbricated pattern.

The spinous process is plate-shaped and extends horizontally to the rear

Puncture is usually performed at the 3rd to 4th or 4th to 5th lumbar intervertebral space.

The line connecting the highest point of the iliac spine corresponds to the spinous process of the fourth lumbar vertebra

Sacrocanal anesthesia is often marked by the sacral angle.
