Cricoid pressure is applied to compress the esophagus against which anatomical structure?

Explanation:
Cricoid pressure works by pressing the cricoid cartilage backward against a firm posterior structure to close off the esophagus. The esophagus sits directly in front of the vertebral column (the spine) in the neck, so pushing on the cricoid cartilage toward the spine compresses the esophageal lumen against the vertebrae, helping prevent regurgitation during airway management. Pressing on the trachea wouldn’t seal the esophagus, since the trachea is anterior to it, and pressing on the mandible wouldn’t provide the necessary posterior resistance to occlude the esophagus.
