CAMRT Radiography Practice Exam

What anatomical landmark is located at the level of C3/C4?

1. Thyroid Cartilage

2. Hyoid Bone

3. Cricoid Cartilage

4. First Cervical Vertebrae

The correct answer is: Hyoid Bone

The correct answer is the hyoid bone, which is anatomically positioned at the level of C3/C4. The hyoid bone is unique because it is the only bone in the human body that does not articulate directly with any other bone. Instead, it is anchored by muscles and ligaments to the surrounding structures in the neck. Located in the anterior midline of the neck, the hyoid bone serves as an important structural component and plays a crucial role in tongue movement and swallowing. Its position at the level of C3/C4 helps radiographers and healthcare professionals identify anatomical relationships, especially during imaging procedures. In contrast, while the thyroid cartilage is located at the level of C4/C5, cricoid cartilage is situated just below the thyroid cartilage at C6, and the first cervical vertebrae (atlas) does not correspond directly to the C3/C4 level. Understanding these landmarks allows for accurate assessments during imaging and clinical evaluations.
