The seventh cervical vertebra is physiologically the last section of the cervical vertebrae, and in a normal person, when the head is lowered, the most prominent part of the lower back of the neck, on the midline, has the most elevated part, which is the location of the seventh cervical spinous process, commonly known as the large vertebral point. The seventh cervical spinous process is the main clinical marker of our body, and it is used in cervical spine examination, physical examination and surgical procedures. The chronic strain on the ligaments above the spinous process of the seventh cervical vertebra can be aggravated by frequent head down playing with cell phones and incorrect sitting posture, resulting in chronic inflammation and pain, and in some cases, hard nodes like calcification of the ligaments at the back of the cervical vertebra, so usually pay attention to protecting and caring for your cervical vertebra.
