CAMRT Radiography Practice Exam

The cricoid cartilage is found at what vertebral level?

1. C4

2. C5

3. C6

4. C7

The correct answer is: C5

The cricoid cartilage is an important anatomical structure located in the human neck as part of the larynx. It is a complete ring of cartilage situated just below the thyroid cartilage and above the trachea. The cricoid cartilage is typically aligned with the sixth cervical vertebra, known as C6. This association is significant as it aids in the identification of airway structures during procedures such as intubation. In this context, understanding the relationship between anatomical landmarks and vertebral levels is crucial for medical professionals, particularly in radiography and emergency medicine. The cricoid ring's prominence at C6 offers guidance for locating the airway and understanding the surrounding structures in relation to imaging techniques. Other levels, such as C4, C5, and C7, may correspond to different anatomical structures but do not accurately represent the position of the cricoid cartilage. C4 is generally associated with the thyroid cartilage, while C7 is known for the vertebra prominence, which does not align with the cricoid's anatomical location. Therefore, recognizing that the cricoid cartilage aligns with C6 provides clarity in understanding the anatomy in relation to vertebral levels.
