The esophagus is divided into three sections: cervical, thoracic, and small abdominal portion.

• A. Cervical, thoracic, small abdominal portion
• B. Cardiac, fundus, body
• C. Upper, middle, lower
• D. Pharyngeal, cervical, thoracic

Answer: (A)

The esophagus runs from the neck down into the abdomen and is divided into three anatomical regions: a cervical portion in the neck, a thoracic portion within the chest, and an abdominal portion after it passes through the diaphragm (often described as a small abdominal portion). The option that lists cervical, thoracic, and small abdominal portion matches this standard division, which is why it’s the best choice. The other options mix in stomach regions (cardiac, fundus, body), use generic top-to-bottom labels (upper, middle, lower) that don’t reflect the esophagus’s standard segmentation, or include the pharynx—another structure entirely that precedes the esophagus rather than being its part.
