The spinous processes of the cervical spine are located at the back of the cervical vertebrae, and there are seven cervical vertebrae from top to bottom, the first through the seventh cervical vertebrae. The first cervical vertebra is also known as the atlas, and the second cervical vertebra is also known as the cardinal vertebra, which often forms the atlantoaxial joint. The spinous processes of the third to seventh cervical vertebrae are relatively large, and the spinous processes of the seventh cervical vertebrae are the largest, and the spinous processes of the seventh cervical vertebrae protrude when the head is lowered, which is also known as the major vertebrae and is usually used as an anatomical landmark for positioning. The seventh cervical vertebra is followed upward by the sixth, fifth, fourth, and third cervical spinous processes. The spinous process is located in the middle of the back of the person, and when pressed, a bulge can be clearly felt. Next to the spinous process is the transverse process, which is usually on the lateral side of the cervical vertebrae, the side of the neck, and usually induces a soreness and swelling when pressed with the hand.
