Verified step by step guidance1
Step 1: Understand the anatomy of the cervical vertebrae. The cervical spine consists of seven vertebrae, labeled C1 through C7. Each vertebra has unique characteristics that distinguish it from the others.
Step 2: Learn the specific features of C7. The seventh cervical vertebra (C7) is called the vertebra prominens because it has a prominent spinous process that can be easily felt at the base of the neck. This feature makes it distinct from other cervical vertebrae.
Step 3: Compare C7 with other cervical vertebrae. For example, C1 (atlas) supports the skull and lacks a spinous process, while C2 (axis) has a dens (odontoid process) for rotation. C5 does not have the prominent spinous process characteristic of C7.
Step 4: Recognize that the term 'vertebra prominens' specifically refers to C7 due to its anatomical prominence and palpability.
Step 5: Confirm that the correct answer to the question is C7, based on its unique feature as the vertebra prominens.
