Verified step by step guidance

Understand the anatomy of the cervical vertebrae: The cervical spine consists of seven vertebrae, labeled C1 through C7. Each has unique features that distinguish them from one another.

Identify the unique feature of C7: C7 is known as the vertebra prominens. This is because it has a prominent spinous process that is easily palpable at the base of the neck.

Compare the spinous process of C7 with other cervical vertebrae: Unlike the other cervical vertebrae, which typically have bifid (split) spinous processes, C7 has a longer and more prominent spinous process that is not bifid.

Eliminate incorrect options: C7 does have an intervertebral disc between it and the next vertebra (T1), and it does not have the dens, which is a feature of C2 (the axis).

Conclude with the correct reason: The defining characteristic of C7 as the vertebra prominens is its larger and more prominent spinous process compared to other cervical vertebrae.
