Which of the cervical vertebrae is also called the vertebra prominens?

The vertebra prominens refers to the seventh cervical vertebra. It is called this because of its prominent spinous process, which can be easily felt through the skin at the base of the neck. This feature makes it distinguishable from the other cervical vertebrae, which generally have shorter and less prominent spinous processes. The vertebra prominens serves as an important anatomical landmark, particularly for clinicians when assessing the cervical spine's alignment and during various medical procedures. Recognizing this specific vertebra is essential in both physical examination and diagnostic imaging.
